The Ford Crown Victoria Police Interceptor (colloquially referred to as the CVPI , P71 , or P7B ) is a four-door, body-on-frame sedan that was manufactured by Ford from 1992 to 2011. It is the police car version of the Ford Crown Victoria and was the first vehicle to use the Ford Police Interceptor name.
128-773: From 1997 to 2013, the Ford Crown Victoria Police Interceptor was the most widely used automobile in law enforcement fleets in North America, namely the United States, Canada and Mexico. It was also used for this purpose on a more limited scale in other regions, such as Europe and the Middle East. After the discontinuation of the Chevrolet Caprice , the Ford Motor Company held a near-monopoly on
256-548: A linear alternator or a rotating armature with a stationary magnetic field is used. In principle, any AC electrical generator can be called an alternator, but usually, the term refers to small rotating machines driven by automotive and other internal combustion engines. An alternator that uses a permanent magnet for its magnetic field is called a magneto . Alternators in power stations driven by steam turbines are called turbo-alternators. Large 50 or 60 Hz three-phase alternators in power plants generate most of
384-453: A CVPI is to look at the VIN tag. The 5th, 6th and 7th digit of the VIN will be "P71" ("P7B" for 2010 and 2011 model years). VIN's with P70 (stretched wheelbase), P72 (1992 and later - commercial heavy duty/taxi and fleet vehicles), P73 (base), P74 (LX), or P75 (1992 touring sedan) are not Police Interceptor models, even if they were equipped/used as "police vehicles". The P70/72 models do share many of
512-410: A LEA's jurisdiction will be geographically divided into operations areas for administrative and logistical efficiency reasons. An operations area is often called a command , division , or office . Colloquially, they are known as beats . While the operations area of a LEA is sometimes referred to as a jurisdiction, any LEA operations area usually still has legal jurisdiction in all geographic areas
640-440: A car with a large back seat. The CVPI came equipped with many heavy-duty parts, such as a revised transmission, and a 186 kW (253 PS; 249 hp) engine. Used versions are normally stripped of any police decals , equipment, police radios, and emergency lights before being sold or auctioned to the public. Though the name has been officially in use since 1992, the 1979–1991 full-sized LTDs and LTD Crown Victorias used
768-415: A cassette deck or CD player. The CVPI also had a calibrated 140 mph (225 km/h) speedometer . The trunk release button was located in the center of the dashboard as opposed to being on the driver door panel (some units were fitted with both of these). The CVPI was available with "dark mode", which disabled overhead interior lighting upon opening a door. The only completely infallible way to identify
896-619: A country, but is made up of personnel from several countries, such as the European Union Police Mission in Bosnia and Herzegovina . International LEAs are typically also multinational, but multinational LEAs are typically not international. LEAs which operate across a collection of countries tend to assist in law enforcement activities, rather than directly enforcing laws, by facilitating the sharing of information necessary for law enforcement between LEAs within those countries. Within
1024-408: A country, the jurisdiction of law enforcement agencies can be organized and structured in a number of ways to provide law enforcement throughout the country. A law enforcement agency's jurisdiction can be for the whole country or for a division or sub-division within the country. When a LEA's jurisdiction is for the whole country, it is usually one of two broad types, either federal or national. When
1152-413: A divisional level. Such exercising of powers is typically specific arrangements between the federal and divisional governing bodies. Examples of federal law enforcement agencies include the: A federated approach to the organization of a country does not necessarily indicate the nature of the organization of law enforcement agencies within the country. Some countries, such as Austria and Belgium , have
1280-577: A heavy duty 11.25" torque converter became standard equipment on all CVPIs. In comparison, the civilian Crown Victoria uses a 12" torque converter. For 2000, the rear fascia and taillights lost the chrome trim, and the gloss-black grille was dropped in favor of a flat-black slatted grille. The black painted mirror caps were now textured plastic, and the ECM received less aggressive calibration as Ford deemed 1999 P71 models as being too aggressively calibrated. Further alterations were made in 2001, but most importantly,
1408-567: A larger capacity radiator along with external power steering, transmission, and engine oil cooler to reduce engine oil temperatures. This allows the vehicles to operate at high rpm/high loads for an extended period of time without the risk of engine oil overheating and subsequent engine damage. This engine oil cooler can be prone to seeping oil from the O-ring seals after the high-mileage operation encountered by CVPIs, particularly where damaged by road salt. The Police Interceptor engine calibration includes

#17328592146091536-533: A law and identify other non-complying subjects. Lawful deception and use of law exemption by a LEA is typically subject to very strong judicial or open civil overview. For example, the Australian Federal Police's controlled operations are subject to open civil review by its governing body, the Parliament of Australia . Law enforcement agencies have other exemptions from laws to allow them to operate in
1664-503: A law by a specified subject. The judicial officer, if they agree, will then issue a legal instrument, typically called a search warrant , to the LEA, which must be presented to the relevant subject if possible. Subjects who do not comply with laws will usually seek to avoid detection by a LEA. When required, in order for the LEA to detect and investigate subjects not complying with laws, the LEA must be able to undertake its activities secretly from
1792-677: A minor change, an accessory belt shield was fitted to the front of the engine, and a new engine cover that featured a silver "V8" emblem was introduced. Lastly, a larger 78 amp hour battery was now standard on the CVPI. The interior was also slightly revised for 2003, with new front seating surfaces that featured improved cloth upholstery and larger headrests; seat-mounted side airbags also became an option. The standard vinyl rear bench and optional cloth rear bench also received new upholstery. Additionally, interior door panels and switch gear were also updated for better ergonomics. Another notable change for 2003
1920-580: A mixture of stainless steel, polymer, and aluminum, as well as 18-inch alloy wheels. By May 2003, the Crown Victoria Police Interceptor accounted for approximately 85% of the police cars in use in the United States. While the exterior design of the 2003 concept vehicle was scrapped, the 2003 model year brought the most extensive changes to the Panther platform since its 1979 introduction. The 2003 model year introduced all new underpinnings with
2048-520: A new grille and taillights. To accommodate the design of the 1995 model's new taillights, the rear license plate was moved from the bumper to the trunk lid. For 1996, the Crown Victoria badge on the front fenders was removed and the cars received a new steering wheel; 1997 models have a lighter blue interior color compared to prior years. For the 1998 model year, the Ford Motor Company restyled
2176-415: A new honeycomb-style grille was made standard, replacing the slat-style grille. Street Appearance Package versions still maintained their chrome bumper trim and chrome slat style grille. Power adjustable pedals also became an option for 2001, as height diversity among officers joining police departments increased. Ford relocated the rear window defrost switch from the left side of the dash to the direct left of
2304-404: A one-way decoupling pulley in order to remedy belt slippage on wide open throttle up shifts. The alternator has a characteristic whine under hard acceleration that can be mistaken for a mechanical issue. The 3.55:1 rear axle returned as an option for 2004, and in a cost-cutting move, the standard heated mirrors were made optional, and the silver bumper trim found on Street Appearance Package models
2432-489: A practical way. For example, many jurisdictions have laws which forbid animals from entering certain areas for health and safety reasons. LEAs are typically exempted from these laws to allow dogs to be used for search and rescue, drug search, explosives search, chase and arrest, etc. This type of exemption is not unique to LEAs. Sight assist dogs are also typically exempted from access restrictions . Members of LEAs may be permitted to openly display firearms in places where this
2560-432: A re-designed and fully boxed hydro-formed steel frame, as well as an aluminum #2 cross-member. According to Ford, the new frame was 20% more resistant to vertical bending and allowed the vehicle to perform better in crashes. For more precise handling, the suspension was significantly revamped, with the addition of coil over front shocks, revised steering knuckles, revised upper and lower control arms, and mono tube rear shocks;
2688-458: A relatively unified approach to law enforcement, but still have operationally separate units for federal law enforcement and divisional policing. The United States has a highly fractured approach to law enforcement agencies generally, and this is reflected in American federal law enforcement agencies . In a federation, there will typically be separate LEAs with jurisdictions for each division within
SECTION 20
#17328592146092816-415: A rotating magnet, called the rotor , turns within a stationary set of conductors, called the stator , wound in coils on an iron core. The field cuts across the conductors, generating an induced EMF (electromotive force), as the mechanical input causes the rotor to turn. The rotating magnetic field induces an AC voltage in the stator windings. Since the currents in the stator windings vary in step with
2944-558: A safety impacting event. These include: Many LEAs have administrative and service responsibilities, often as their major responsibility, as well as their law enforcement responsibilities. This is typical of agencies such as customs or taxation agencies, which provide services and facilities to allow subjects to comply with relevant laws as their primary responsibilities. Private police are law enforcement bodies that are owned or controlled by non-governmental entities. Private police are often utilized in places where public law enforcement
3072-431: A safety issue because the lights would flash when officers exited the vehicle and locked the doors, potentially giving their presence away at night. The car received new styled door moldings, and Ford placed a "Flex Fuel" badge in the lower right corner of the rear fascia. The Street Appearance Package also received the same new door moldings as found on the civilian-fleet-only Crown Victoria LX. The 2009 CVPI now mandated
3200-525: A slightly higher idle speed (by around 40 rpm) and minor changes in the emissions settings. The computer is tuned for more aggressive transmission shift points, and the transmission itself uses a smaller heavy-duty 11.25" (1999-2011) torque converter compared to the 12" torque converter on a standard Crown Victoria. The EGR system is controlled differently on '03 and older vehicles than on non-police vehicles. The 2004–2011 Police Interceptors are equipped standard with an open 3.27:1 rear axle (axle code Z5), with
3328-416: A small amount of electricity, just enough to excite the field coils of the connected alternator to generate electricity. A variation of this system is a type of alternator that uses direct current from a battery for initial excitation upon start-up, after which the alternator becomes self-excited. This method of excitation consists of a smaller alternating-current (AC) generator fixed on the same shaft as
3456-437: A specific jurisdiction through the employment and deployment of law enforcement officers and their resources. The most common type of law enforcement agency is the police , but various other forms exist as well, including agencies that focus on specific legal violation , or are organized and overseen by certain authorities . They typically have various powers and legal rights to allow them to perform their duties, such as
3584-504: A stainless-steel single exhaust system , while the Handling and Performance Package and LX Sport-equipped Crown Victorias have the same exhaust system as the CVPI, with the resonators. The resonators further reduce noise, vibration, and harshness without adding any restriction to the exhaust system. CVPIs have higher-rate coil springs , around 0.8 inches (20.3 mm) of additional ground clearance, and thinner rear anti-roll bars (shared with
3712-405: A standard vinyl bench, however, both cloth and velour rear seats were optional. CVPIs came standard with heavy-duty flooring, but this could be removed in favor of carpeting. All CVPIs had a non-leather wrapped steering wheel, with cruise control being an available option throughout the model run. All CVPIs came standard with a basic four-preset AM/FM radio, however, there was the option to add either
3840-434: A subject with regulations or codes of practice may result in the revocation of a license for the subject to operate, and operating without a licence is typically illegal. Also, the failure to apply codes of practice can impact other subjects' safety and life, which can also be illegal. A LEA can be responsible for enforcing secular law or religious law such as Sharia or Halakha . The significant majority of LEAs around
3968-464: A traction-lock (Trac-Lok) 3.27:1 rear axle (axle code X5) optional, and are electronically limited to 129 mph (208 km/h) due to critical drive-line speed limitations. An optional 3.55:1 traction-lock rear axle ratio with 119 mph speed limiter was also available from 2004 to 2011 (axle code C6). The 1999-mid 2001 CVPIs were equipped with a standard 3.55:1 rear axle ratio and were limited to about 124 mph (200 km/h). This compares to

4096-539: A weight sensing passenger airbag function. Midway through the model year, a 31-spline rear axle was introduced as standard equipment. A trunk circulation fan was offered as a factory option. 2006 introduced a redesigned instrument cluster with an analog speedometer, tachometer, digital odometer with hour meter and trip meter features, and cross-compatibility with the civilian version's various features (these are normally locked out, but can be accessed through wiring modification). Kevlar -lined front doors were made optional on
4224-487: Is N = 120 f / P {\displaystyle N=120f/P} , where f {\displaystyle f} is the frequency in Hz (cycles per second). P {\displaystyle P} is the number of poles (2, 4, 6, …), and N {\displaystyle N} is the rotational speed in revolutions per minute (r/min). Old descriptions of alternating current systems sometimes give
4352-405: Is a direct jurisdictional responsibility and is different from the situation when a governing body makes arrangements with another governing body's LEA to provide law enforcement for its subjects. In federal polities, actions that violate laws in multiple geographical divisions within the federation are escalated to a federal LEA. In other cases, specific crimes deemed to be serious are escalated; in
4480-442: Is a type of alternator that uses direct current from a battery for initial excitation upon start-up, after which the alternator becomes self-excited. This method depends on residual magnetism retained in the iron core to generate a weak magnetic field, which would allow a weak voltage to be generated. This voltage is used to excite the field coils so the alternator can generate stronger voltage as part of its build up process. After
4608-415: Is commonly understood by society, it is recognized formally by scholars and academics. A police agency's jurisdiction for social order and public safety will normally be the same as its jurisdiction for law enforcement. Military organizations often have law enforcement units. These units within armed forces are generally referred to as military police . This may refer to: The exact usage and meaning of
4736-497: Is divided into 77 precincts. Sometimes, the one legal jurisdiction is covered by more than one LEA, again for administrative and logistical efficiency reasons, or arising from policy, or historical reasons. In England and Wales , LEAs called constabularies have jurisdiction over their respective areas of legal coverage, but they do not normally operate out of their areas without formal liaison between them. The primary difference between separate agencies and operational areas within
4864-409: Is fed into the rotating field coils through the voltage regulator (VR). This increases the magnetic field around the field coils, which induces a greater voltage in the armature coils. Thus, the output voltage is brought back up to its original value. Alternators used in central power stations also control the field current to regulate reactive power and to help stabilize the power system against
4992-491: Is for social order within their jurisdiction and the relevant social order being highly codified as laws. Often, a LEA will have a specific internal unit to ensure that the LEA is complying with relevant laws such as the U.S. Federal Bureau of Investigation's Office of Professional Responsibility. In some countries and regions, specialised or separate LEAs are established to ensure that other LEAs comply with laws and investigate potential violations of laws by law enforcers, like
5120-463: Is often used in the United States to refer to police agencies, however, it also includes agencies with peace officer status or agencies which prosecute criminal acts. A county prosecutor or district attorney is considered to be the chief law enforcement officer of a county. Other responsibilities of LEAs are typically related to assisting subjects to avoid non-compliance with a law, assisting subjects to remain safe and secure, assisting subjects after
5248-881: Is seen as being under-provided. For example, the San Francisco Patrol Special Police was formed to increase security in San Francisco during the California gold rush , and presently still exists to protect locations on the request of private clients. In Canada and the United States, many railroad companies have private railroad police. Examples include the BNSF Police Department , Canadian National Police Service , Canadian Pacific Kansas City Police Service , Union Pacific Police Department , etc. The Canadian National Police Service and Canadian Pacific Kansas City Police Service operate in both countries while

5376-448: Is that a small DC exciter current indirectly controls the output of the main alternator. Another way to classify alternators is by the number of phases of their output voltage. The output can be single phase or polyphase. Three-phase alternators are the most common, but polyphase alternators can be two-phase, six-phase, or more. The revolving part of alternators can be the armature or the magnetic field. The revolving armature type has
5504-496: Is the United Nations Police , which helps provide law enforcement during United Nations peacekeeping missions. To enable a LEA to prevent, detect, and investigate non-compliance with laws, the LEA is endowed with powers by its governing body which are not available to non LEA subjects of a governing body. Typically, a LEA is empowered to varying degrees to: These powers are not available to subjects other than LEAs within
5632-431: Is typically prohibited to civilians, violate various traffic laws in the course of their duties, or detain persons against their will. Alternator An alternator is an electrical generator that converts mechanical energy to electrical energy in the form of alternating current . For reasons of cost and simplicity, most alternators use a rotating magnetic field with a stationary armature . Occasionally,
5760-474: The Alexanderson alternator were developed as longwave radio transmitters around World War 1 and used in a few high power wireless telegraphy stations before vacuum tube transmitters replaced them. A conductor moving relative to a magnetic field develops an electromotive force (EMF) in it ( Faraday's Law ). This EMF reverses its polarity when it moves under magnetic poles of opposite polarity. Typically,
5888-576: The Drug Enforcement Administration would not, as even though they investigate drug smuggling , their jurisdiction does not cover specifically tobacco smuggling. In other cases, an LEA's involvement is determined based on whether their involvement is requested; the Australian Federal Police , for instance, has jurisdiction over all of Australia , but usually takes on complex serious matters referred to it by another agency, and
6016-799: The National Public Security Force —but the Highway Police, Railroad Police, and Penal Police are restricted to specific area jurisdictions (the Brazilian Highway System , railways , and prisons respectively) and do not investigate crimes , the Federal Police performs various police duties across the country and does investigate crimes, while the National Public Security Force is a rapid reaction force deployed to assist state authorities on request. Often,
6144-643: The New South Wales Independent Commission Against Corruption or the Ontario Special Investigations Unit . Typically, a LEA is established and constituted by the governing body it is supporting, and the personnel making up the LEA are from the governing body's subjects. For reasons of either logistical efficiency or policy, some divisions with a country will not establish their own LEAs but will instead make arrangements with another LEA, typically from

Sometimes, an LEA's jurisdiction is determined by the type of violation committed relative to
6400-461: The power of arrest and the use of force . LEAs which have their ability to apply their powers restricted in some way are said to operate within a jurisdiction . Jurisdictions are traditionally restricted to a geographic area and territory. LEA might be able to apply its powers within a state (e.g. the National Police for the entirety of France ), within an administrative division (e.g.
6528-401: The prime mover turns an alternator which provides electricity for the traction motors (AC or DC). The traction alternator usually incorporates integral silicon diode rectifiers to provide the traction motors with up to 1,200 volts DC. The first diesel electric locomotives, and many of those still in service, use DC generators as, before silicon power electronics, it was easier to control

#17328592146096656-416: The "Crown Victoria Police Interceptor" name, with a badge on the trunk lid replacing the 1998 "Crown Victoria" badge (Though very early 1999 models still retained the "Crown Victoria" badging). A chrome-trimmed gloss-black rear fascia, black door-handle trim, black bumper strips, and a gloss-black slatted grille were also introduced at this time. Finally, the new Street Appearance Package (SAP), intended to make
6784-465: The "P72" production code designation for both fleet and taxi and police models, with the model itself being internally classified as S (similar to LX). From 1992 to 1997, the police car models of the Crown Victoria (both base and LX trims) were officially known as Crown Victoria P71s. In the 1993 model year, the Crown Victoria was given a chrome front grille and a reflector strip between the taillights . Another minor restyle followed suit in 1995, with
6912-432: The "Police Interceptor" badge that replaced the standard "Crown Victoria" badge on the bottom left trunk lid, although all SAP models used the standard Crown Victoria marking instead. Police Interceptor badges are readily available online, so this identifying technique is the least reliable. Law enforcement agency A law enforcement agency ( LEA ) is any government agency responsible for law enforcement within

Another difference is Ford's "severe duty" shock absorbers that offer a stiffer ride than the standard Crown Victoria. They also have black steel wheels with stainless steel or chromed plastic hubcaps. All CVPIs also come with T-409 stainless-steel, dual exhaust systems without resonators. Standard Crown Victorias come with
7168-483: The 2009 model year, the CVPI now had power pedals, side airbags, and federally mandated recessed window switches as standard equipment. The CVPI also received upgraded brakes for 2009, although specifics about them are not available. The confirmation flash that occurs when the doors are locked is now automatically disabled when the Courtesy Lamp Disable option is ordered. The confirmation flash was considered to be

7424-403: The Australian Federal Police is a federal agency and has the legal power to enforce the laws enacted by any Australian state, but will generally only enforce state law if there is a federal aspect to investigate. Typically, federal LEAs have relatively narrow police responsibilities, the individual divisions within the federation usually establish their own police agencies to enforce laws within
7552-460: The CVPI look like a standard (P73) model, including chrome trimming and Crown Victoria badging, was introduced. Midway through 1999, the taillights were also changed; 1998 and early 1999 models had a separate amber turn signal along the bottom edge of each taillight housing. Starting in mid-1999, the extra bulbs were eliminated and the turn signals returned to the combination of stop/turn setup with red lenses found in many North American cars. Although
7680-447: The CVPI now received the “Performance Improved” 4.6L 2V V8 engine as standard equipment. It made 235 hp @4,750 RPM and 276 lb-ft of torque at 4,000 RPM. In a corresponding move, the ECM was once again re-calibrated and the P71 sported a more powerful 135/82 amp alternator . The 3.55:1 rear differential was also deleted in favor of a 3.27:1 unit. All plastic bumper trim was deleted and
7808-488: The CVPI received its final horsepower upgrade, using a new air intake borrowed from the Mercury Marauder . The 2004–2011 CVPI is rated for 186.5 kW (254 PS; 250 hp) @4,900 RPM. This better-flowing air intake system also has an integrated 80 mm (3.1 in) mass airflow (MAF) sensor that is part of the airbox lid (but can be serviced individually). This allows for much more precise flow calibration and reduces

Both cars included restyled front and rear end components. The 1998 police package P71 had a chrome grille, chrome door handle trim, chrome bumper strips, and a chrome-trimmed flat-black rear fascia with the "Crown Victoria" badge. In 1999, Ford introduced
8192-506: The HVAC controls. The Ford logo on the steering wheel was now blue instead of being color coded to the interior. There were no changes made to the 2002 CVPI aside from the addition of power mirrors as standard equipment. At the 2002 New York International Auto Show , a 2003 Ford Police Interceptor concept car was previewed featuring an all new exterior, mirror-mounted spotlights, a 300 hp V8 engine, reinforced front and rear bumpers made out of

Usually, these powers are only allowed when it can be shown that a subject is probably already not complying with a law. For example, to undertake an intrusive search, typically a LEA must make an argument and convince a judicial officer of the need to undertake the intrusive search on the basis that it will help detect or prove non-compliance with

In circumstances where the United Nations is already providing an administrative support capability within the country, the United Nations may directly establish and constitute a LEA on behalf of the country, as occurred under the United Nations Transitional Administration in East Timor , which operated in Timor-Leste from 1999 to 2002; related
8832-527: The United States, the FBI has responsibility for the investigation of all kidnapping cases, regardless of whether it involves the crossing of state lines. Some countries provide law enforcement on land and in buildings owned or controlled by the federation by using a federal LEA; for example, the U.S. Department of Homeland Security is responsible for some aspects of federal property law enforcement Typically, LEAs working in different jurisdictions which overlap in
8960-613: The agency will undertake its own investigations of less serious or complex matters by consensus. LEA jurisdictions for a country and its divisions can typically be at more than one level. The United States has five basic tiers of law enforcement jurisdiction: federal , state , county , municipality , and special jurisdiction ( tribal , airport , transit , railroad , etc.). Only the municipal, county, and state levels are involved in direct policing (i.e. uniformed officers with marked cars and regular patrols), and these can still depend on each agency's role and function. As an example for
9088-442: The alternator. The AC stator generates a small amount of field coil excitation current, which is induced in the rotor and rectified to DC by a bridge rectifier built in to the windings where it excites the field coils of the larger connected alternator to generate electricity. This system has the advantage of not requiring brushes, which increases service life, although with a slightly lower overall efficiency. A variation of this system
9216-438: The armature wound on the rotor, where the winding moves through a stationary magnetic field. The revolving armature type is not often used. The revolving field type has a magnetic field on the rotor to rotate through a stationary armature winding. The advantage is that then the rotor circuit carries much less power than the armature circuit, making the slip ring connections smaller and less costly; only two contacts are needed for
9344-410: The battery to adjust the charging voltage and an over-temperature sensor on the actual alternator to protect it from overheating. High-frequency alternators of the variable-reluctance type were applied commercially to radio transmission in low-frequency radio bands. These were used for transmitting Morse code and, experimentally, for transmitting voice and music. In the Alexanderson alternator , both
9472-410: The chances of air leakage. The P71 zip tube (the flexible rubber hose between the throttle body and MAF outlet) is also used to reduce NVH (noise, vibration, and harshness) as well as transfer air from the airbox to the throttle body with minimal flow resistance. The 2004 CVPI also included a 200 amp heavy-duty alternator manufactured by Mitsubishi . The new alternator was computer controlled and featured
9600-399: The combined responsibilities that federal LEAs and divisional LEAs would have in a federated country. National LEAs are usually divided into operational areas. To help avoid confusion over jurisdictional responsibility, some federal LEAs, such as the U.S. FBI, explicitly advise that they are not a national law enforcement agency. A national police agency is a national LEA that also has
9728-446: The cost of the magnet material. Since the permanent magnet field is constant, the terminal voltage varies directly with the speed of the generator. Brushless AC generators are usually larger than those used in automotive applications. An automatic voltage control device controls the field current to keep the output voltage constant. If the output voltage from the stationary armature coils drops due to an increase in demand, more current
9856-490: The country has a federal constitution , an LEA responsible for the entire country is referred to as a federal law enforcement agency . The responsibilities of a federal LEA vary from country to country. Federal LEA responsibilities are typically countering fraud against the federation, immigration and border control regarding people and goods, investigating currency counterfeiting, policing of airports and protection of designated national infrastructure, national security, and
9984-418: The direct-current rotor, whereas often a rotor winding has three phases, and multiple sections which would each require a slip-ring connection. The stationary armature can be wound for any convenient medium voltage level, up to tens of thousands of volts; manufacture of slip ring connections for more than a few thousand volts is costly and inconvenient. Many alternators are cooled by ambient air, forced through
10112-425: The division. However, in some countries federal agencies have jurisdiction in divisions of the federation. This typically happens when the division does not have its own independent status and is dependent on the federation. The Royal Canadian Mounted Police (RCMP) is one such federal agency that also acts as the sole police agency for Canada's three territories , Northwest Territories , Nunavut , and Yukon . This
10240-401: The effects of momentary faults . Often, there are three sets of stator windings, physically offset so that the rotating magnetic field produces a three phase current, displaced by one-third of a period with respect to each other. One cycle of alternating current is produced each time a pair of field poles passes over a point on the stationary winding. The relation between speed and frequency
10368-463: The enclosure by an attached fan on the shaft that drives the alternator. In vehicles such as transit buses, a heavy demand on the electrical system may require a large alternator to be oil-cooled. In marine applications water-cooling is also used. Expensive automobiles may use water-cooled alternators to meet high electrical system demands. Most power generation stations use synchronous machines as their generators. The connection of these generators to
10496-476: The federal government, and reduces the number of agencies policing the same geographical area. In circumstances where a country or division within a country is not able to establish stable or effective LEAs, typically police agencies, the country might invite other countries to provide personnel, experience, and organisational structure to constitute a LEA, such as the Regional Assistance Mission to
10624-436: The federation. A federal LEA will have primary responsibility for laws which affect the federation as whole, and which have been enacted by the governing body of the federation. Members of a federal LEA may be given jurisdiction within a division of a federation for laws enacted by the governing bodies of the divisions either by the relevant division within the federation, or by the federation's governing body. By way of example,
10752-666: The form of higher-tier agencies assisting lower-tier agencies. In some countries, national or federal police may be involved in direct policing as well, though what they focus on and what their duties are may vary. In Brazil , there are five federal police forces with national jurisdiction—the Federal Police of Brazil , the Federal Highway Police , the Federal Railroad Police , the Federal Penal Police, and
10880-407: The frequency in terms of alternations per minute, counting each half-cycle as one alternation ; so 12,000 alternations per minute corresponds to 100 Hz. An alternator's output frequency depends on the number of poles and the rotational speed. The speed corresponding to a particular frequency is called the synchronous speed . This table gives some examples: Alternators may be classified by
11008-406: The front-wheel-drive competition for rough driving over curbs and other obstacles in the urban environment. Although CVPIs were not sold directly to the general public by the manufacturer, they were widely available in North America as used vehicles after being decommissioned. The cars were in demand by taxi companies and others who wanted a safe, durable, and/or inexpensive car, and those who needed
11136-444: The generator. The early machines were developed by pioneers such as Michael Faraday and Hippolyte Pixii . Faraday developed the "rotating rectangle", whose operation was heteropolar – each active conductor passed successively through regions where the magnetic field was in opposite directions. Lord Kelvin and Sebastian Ferranti also developed early alternators, producing frequencies between 100 and 300 Hz . The late 1870s saw
11264-479: The heavy duty mechanical/cooling/suspension upgrades of the P71. There are several visual clues to determine if a vehicle is a Police Interceptor without looking at the VIN, but most can be "forged" to look like one, or are different with the P71 Street Appearance Package (SAP). Some owners are also known to alter their P71 and make it look more like a civilian Crown Vic. In 1999, Ford began using
11392-445: The hood. An engine knock sensor and revised engine tuning increased horsepower and torque ratings for the 2003 CVPI to 239 hp and 287 lb-ft of torque. Additionally, the entire exhaust system was re-designed, with exhaust hangers now mounted to the frame rails; this allowed for a reduction in interior noise. For improved carbon emissions, the EGR system was revamped, and the fuel system
11520-432: The initial AC voltage buildup, the field is supplied with rectified voltage from the alternator. A brushless alternator is composed of two alternators built end-to-end on one shaft. Until 1966, alternators used brushes with rotating field. With the advancement in semiconductor technology, brushless alternators are possible. Smaller brushless alternators may look like one unit, but the two parts are readily identifiable in
11648-500: The interests of the country as a whole (e.g. United Kingdom 's His Majesty's Revenue and Customs ). Many law enforcement agencies are police agencies that have a broad range powers and responsibilities. Police agencies, however, also often have a range of responsibilities not specifically related to law enforcement. These responsibilities relate to social order and public safety. While this understanding of policing, being more encompassing than just law enforcement has grown with and
11776-416: The introduction of the first large-scale electrical systems with central generation stations to power Arc lamps , used to light whole streets, factory yards, or the interior of large warehouses. Some, such as Yablochkov arc lamps introduced in 1878, ran better on alternating current, and the development of these early AC generating systems was accompanied by the first use of the word "alternator". Supplying
11904-527: The jurisdiction of the Illinois State Police . All three technically have overlapping jurisdictions, and though their regular duties are fairly different and they typically avoid each other's responsible areas (the Cook County Sheriff's Office typically avoids patrolling Chicago unless it is for penal or court-related duties), they are still capable of assisting each other if necessary, usually in
12032-429: The large versions. The main alternator is the larger of the two sections, and the smaller one is the exciter. The exciter has stationary field coils and a rotating armature (power coils). The main alternator uses the opposite configuration with a rotating field and stationary armature. A bridge rectifier , called the rotating rectifier assembly, is mounted on the rotor. Neither brushes nor slip rings are used, which reduces
12160-659: The laws the LEA enforces, who or what the violation affects, or the seriousness of the violation. For example, in the United States, the Postal Inspection Service primarily investigates crimes affecting or misusing the services of the United States Postal Service , such as mail and wire fraud . If, hypothetically, a Postal Inspection Service investigation uncovered tobacco smuggling , the Bureau of Alcohol, Tobacco, Firearms and Explosives would be involved, but
12288-431: The lenses changed, the housings did not. They still had the chambers for the separate turn signals that early models had. These chambers were now empty, leaving a perfect place to install in police cars strobe tubes that would not affect brake or turn-signal visibility. Fleet models equipped with the "Street Appearance Package" retained the amber turn signal until 2004, when all CVs changed to all-red taillights. For 1999,
12416-405: The market for police vehicles in the United States and Canada for over a decade. The conventional rear-wheel drive , V8 power, and body-on-frame construction were considered advantageous for police use. The body-on-frame construction allowed inexpensive repairs after collisions without the need to straighten the chassis . Rear-wheel drive was deemed better for hard maneuvers and more robust than
12544-446: The method of excitation, number of phases, the type of rotation, cooling method, and their application. There are two main ways to produce the magnetic field used in the alternators: by using permanent magnets , which create their persistent magnetic field, or by using field coils . The alternators that use permanent magnets are specifically called magnetos . In other alternators, wound field coils form an electromagnet to produce
12672-616: The new rear shocks were now inverted and mounted to the outside of the frame rails. For more precise steering, the recirculating ball power steering system was replaced with an all new rack and pinion unit that was 22.5 pounds lighter than the outgoing setup. The brakes were also redesigned, with the addition of a quiet EBD brake booster that optimized front-rear brake bias; it also featured a mechanical panic assist. These changes contributed to 2003 and newer CVPIs having significantly better handling characteristics in comparison to their 2002 and older counterparts. Several changes were also made under
12800-490: The non-complying subject. This, however, may require the LEA to explicitly not comply with a law other subjects must comply with. To allow the LEA to operate and comply with the law, it is given lawful exemption to undertake secret activities. Secret activities by a LEA are often referred to as covert operations . To deceive a subject and carry out its activities, a LEA may be lawfully allowed to secretly: to typically collect information about and evidence of non-compliance with
12928-435: The number of wearing parts. The main alternator has a rotating field and a stationary armature (power generation windings). Varying the amount of current through the stationary exciter field coils varies the 3-phase output from the exciter. This output is rectified by a rotating rectifier assembly mounted on the rotor, and the resultant DC supplies the rotating field of the main alternator and hence alternator output. The result
13056-887: The one legal jurisdiction is the degree of flexibility to move resources between versus within agencies. When multiple LEAs cover the one legal jurisdiction, each agency still typically organizes itself into operations areas. In the United States, within a state's legal jurisdiction, county and city LEAs do not have full legal jurisdictional flexibility throughout the state, and this has led in part to mergers of adjacent police agencies. Jurisdictionally, there can be an important difference between international LEAs and multinational LEAs, even though both are often referred to as "international", even in official documents. An international law enforcement agency has jurisdiction and or operates in multiple countries and across state borders, such as Interpol . A multinational law enforcement agency will typically operate in only one country, or one division of
13184-447: The others operate only in the US. Many LEAs are also involved in the monitoring or application of regulations and codes of practice. See, for example, Australian Commercial Television Code of Practice , building code , and code enforcement . Monitoring of the application of regulations and codes of practice is not normally considered law enforcement. However, the consistent non-compliance by
13312-440: The position of the rotor, an alternator is a synchronous generator. The rotor's magnetic field may be produced by permanent magnets or by a field coil electromagnet. Automotive alternators use a rotor winding, which allows control of the alternator's generated voltage by varying the current in the rotor field winding. Permanent magnet machines avoid the loss due to magnetizing current in the rotor, but are restricted in size due to
13440-531: The power may be split between the engine starting battery and the domestic or house battery (or batteries) by use of a split-charge diode ( battery isolator ) or a voltage-sensitive relay. Due to the high cost of large house battery banks, Marine alternators generally use external regulators. Multistep regulators control the field current to maximize the charging effectiveness (time to charge) and battery life. Multistep regulators can be programmed for different battery types. Two temperature sensors can be added: one for
13568-832: The proper amount of voltage from generating stations in these early systems was left up to the engineer's skill in "riding the load". In 1883 the Ganz Works invented the constant voltage generator that could produce a stated output voltage, regardless of the value of the actual load. The introduction of transformers in the mid-1880s led to the widespread use of alternating current and the use of alternators needed to produce it. After 1891, polyphase alternators were introduced to supply currents of multiple differing phases. Later alternators were designed for various alternating current frequencies between sixteen and about one hundred hertz for use with arc lighting, incandescent lighting, and electric motors. Specialized radio frequency alternators like
13696-455: The protection of the country's head of state and of other designated very important persons, such as the U.S. Secret Service or the U.S. Department of State Diplomatic Security Service . A federal police agency is a federal LEA that also has the typical police responsibilities of social order and public safety as well as federal law enforcement responsibilities. However, a federal police agency will not usually exercise its powers at
13824-419: The relevant sub-national jurisdiction, and may cooperate in law enforcement activities with municipal or national police where either exist. LEAs can be responsible for the enforcement of laws affecting the behavior of people or the general community (e.g. New York City Police Department ), the behavior of commercial organizations and corporations (e.g. Australian Securities and Investments Commission ), or for
13952-417: The rotating magnetic field. A device that uses permanent magnets to produce alternating current is called a permanent magnet alternator (PMA). A permanent magnet generator (PMG) may produce either alternating current or direct current if it has a commutator . This method of excitation consists of a smaller direct-current (DC) generator fixed on the same shaft as the alternator. The DC generator generates
14080-414: The salt-water environment. Marine alternators are designed to be explosion proof (ignition protected) so that brush sparking will not ignite explosive gas mixtures in an engine room environment. Depending on the type of system installed, they may be 12 or 24 volts. Larger marine diesels may have two or more alternators to cope with the heavy electrical demand of a modern yacht. On single alternator circuits,
14208-539: The same country, to provide law enforcement within the division. For example, the Royal Canadian Mounted Police (RCMP) is a federal agency and is contracted by most of Canada 's provinces and many municipalities to police them, even though law enforcement in Canada is constitutionally a divided responsibility. This arrangement has been achieved by formal agreement between those provinces and municipalities and
14336-443: The shifter on the steering column. This gap between seats is generally filled by a console holding radios, controls for emergency equipment, large firearms, and often a laptop computer or mobile data terminal . A velour split-bench seat was optional, with a power-adjustable driver's seat being optional on both the split bench and standard bucket seats. All front bucket seats came with stab-proof seat backs. The rear seats were offered as
14464-506: The speed of DC traction motors. Most of these had two generators: one to generate the excitation current for a larger main generator. Optionally, the generator also supplies head-end power (HEP) or power for electric train heating . The HEP option requires a constant engine speed, typically 900 r/min for a 480 V 60 Hz HEP application, even when the locomotive is not moving. Marine alternators used in yachts are similar to automotive alternators, with appropriate adaptations to
14592-416: The standard non-P71 2.73 rear axle ratio with a speed limitation of 110 mph (177 km/h) for all "civilian" Crown Victorias. Ford used an aluminum matrix composite driveshaft for the 1999–2001 CVPIs as a measure to allow safe operation at high speeds with the 3.55:1 gear ratio, but it was more expensive than the regular aluminum driveshafts and was eliminated with the 3.55:1 rear axle midway through
14720-662: The subject of a recall. Midway through the 2003 model year, Ford de-contented the CVPI along with the rest of the Panther platform line. The CVPI saw the removal of the remote locking fuel door, auto parking brake pedal release, foam insulators inside the headliner, silver "V8" emblem on the engine cover, and an engine compartment lamp. Ford estimated that de-contenting the Panther platform lineup would save US$ 4,000,000 in production costs per year. These changes took effect in December 2002, and vehicles produced after this date are often referred to as "2003.5" and "2003 Job #2" models. For 2004,
14848-514: The terms military police , provost , security forces , and gendarmerie vary from country to country. Non-military law enforcement agencies are sometimes referred to as civilian police , but usually only in contexts where they need to be distinguished from military police. However, they may still possess a military-like structure and protocol. In most countries, the term law enforcement agency when used formally includes agencies other than only police agencies. The term law enforcement agency
14976-437: The type of law non-compliance actively establish mechanisms for cooperation, establish joint operations and joints task forces. Often, members of a LEA working outside of their normal jurisdiction on joint operations or task force are sworn in as special members of the host jurisdiction. A national law enforcement agency is a LEA in a country which does not have divisions capable of making their own laws. A national LEA has
15104-758: The typical police responsibilities of social order and public safety as well as national law enforcement responsibilities. Examples of countries with non-federal national police agencies are New Zealand , Italy , Indonesia , France , Ireland , Japan , Netherlands , Malaysia , the Philippines , and Nicaragua . State police , provincial police , or regional police are a type of subnational territorial police force found in nations organized as federations , typically in North America , South Asia , and Oceania , because each of their state police are mostly at country level. These forces typically have jurisdiction over
15232-445: The use of Mercon LV fluid in the 4R75E transmission. In 2010, the VIN code "P71" was replaced with "P7B". No other changes were made. 2011 models received updated and larger front headrests along with the rest of the Crown Victoria line in order to comply with new front crash-rating standards. This was the last model year for the CVPI and no other changes were made from 2010. The final CVPI
15360-482: The utility grid requires synchronization conditions to be met. Alternators are used in modern internal combustion engine automobiles to charge the battery and to power the electrical system when its engine is running. Until the 1960s, automobiles used DC dynamo generators with commutators . With the availability of affordable silicon-diode rectifiers, alternators were used instead. In later diesel-electric locomotives and diesel electric multiple units ,
15488-419: The world are secular, and their governing bodies separating religious matters from the governance of their subjects. Religious law enforcement agencies, such as Saudi Arabia 's Mutaween or Iran 's Guidance Patrol , exist where full separation of government and religious doctrine has not occurred, and are generally considered police agencies, typically religious police , because their primary responsibility
15616-410: The world's electric power, which is distributed by electric power grids . Alternating current generating systems were known in simple forms from the discovery of the magnetic induction of electric current in the 1830s. Rotating generators naturally produced alternating current, but since there was little use for it, it was normally converted into direct current via the addition of a commutator in
15744-421: Was introduced with better off the line performance than previous versions. No changes were introduced for the 2007 model year, aside from the rear shocks having returned to a right-side up design. For 2008, the Crown Victoria was restricted to fleet-only sales, and all Panther platform vehicles became Flex Fuel cars, making them compatible with E85 fuel. The CVPI also received keyless entry abilities. For
15872-410: Was now return-less. A larger 6-quart oil pan was also made standard, and the oil fill cap was moved to the passenger side valve cover. The intake manifold was revised and now included an aluminum coolant crossover and deeper intake runners. For better cooling, a new, variable speed electric cooling fan replaced the two-speed unit, and the power steering fluid reservoir was now mounted to the fan shroud. In
16000-569: Was purchased by the Kansas Highway Patrol in 2011. As of 2023, the Los Angeles County Sheriff's Department has more than 400 CVPIs in service. Both cars use the same 4.6 L 2V SOHC V8 (both Flex Fuel starting in 2008), Ford modular engine , and Ford four-speed automatic transmission . However, a few notable differences exist between the CVPI and a standard Crown Victoria or Grand Marquis. All CVPIs are equipped with
16128-438: Was removed from the rear window and moved to the rear quarter panel (only for the 2005 MY). The throttle body is no longer manually operated by a cable, but by an electronic drive-by-wire set up. This move also corresponded with the addition of a slightly updated, electronically controlled 4R70E transmission, which was only used for the 2005 model year. A heated PCV valve was made standard, as were front crash severity sensors with
16256-449: Was removed. 2005 introduced an optional fire suppression system, an industry first. It was touted to decrease the chances of a fire from starting in rear impact collisions. Vehicles equipped with a fire suppression system can be easily identified by a large encased button mounted on the headliner forward of the map lights. A new steering wheel was introduced for 2005, and the AM/FM radio antenna
16384-410: Was the addition of 7-hole 16x8 inch steel wheels, replacing the old concave 20-hole steel wheels. A 2003 model can be told apart from its 1998-2002 counterpart models by simply examining the wheels. Due to the new underpinnings, the wheels for the new cars had a much higher offset and look almost flat. Along with a new wheel design, new hubcaps were introduced. These new 7-hole steel wheels were eventually
