60-399: (Redirected from E-Class ) E class may refer to: Automobiles [ edit ] Mercedes-Benz E-Class , a series of automobiles built by Mercedes-Benz Chrysler E-Class , a mid-sized car produced between 1983 and 1984 E-segment , a European vehicle size class Ships [ edit ] British E-class submarine , submarines of

120-405: A hot-bulb engine used a 'jerk pump' to dispense fuel oil at high pressure to an injector. Another development in early diesel engines was the pre-combustion chamber, which was invented in 1919 by Prosper l'Orange to avoid the drawbacks of air-blast injection systems. The pre-combustion chamber made it feasible to produce engines in size suitable for automobiles and MAN Truck & Bus presented

180-610: A spark plug . The Cummins Model H diesel truck engine was introduced in America in 1933. In 1936, the Mercedes-Benz OM 138 diesel engine (using a precombustion chamber) became one of the first fuel-injected engines used in a mass-production passenger car. During World War II , several petrol engines for aircraft used direct-injection systems, such as the European Junkers Jumo 210 , Daimler-Benz DB 601 , BMW 801 , and

240-451: A carburettor. Many of the carburettor's supporting components—such as the air filter, intake manifold, and fuel line routing—could be used with few or no changes. This postponed the redesign and tooling costs of these components. Single-point injection was used extensively on American-made passenger cars and light trucks during 1980–1995, and in some European cars in the early and mid-1990s. In the US,

300-581: A central injector instead of multiple injectors. Single-point injection (also called 'throttle-body injection') uses one injector in a throttle body mounted similarly to a carburettor on an intake manifold . As in a carburetted induction system, the fuel is mixed with the air before entering the intake manifold. Single-point injection was a relatively low-cost way for automakers to reduce exhaust emissions to comply with tightening regulations while providing better "driveability" (easy starting, smooth running, no engine stuttering) than could be obtained with

360-474: A complex array of motion sensors, radars, and cameras to scan the road ahead, and requires the driver's hands to be placed on the wheel at all times. This feature was also available on the fourth-generation Mercedes-AMG E 63 model. In 2020, Mercedes-Benz introduced a facelift to the W213. The sixth generation E-Class debuted on April 25, 2023. Starting from this generation, coupés and convertibles will no longer bear

420-572: A fuel injection system are described in the following sections. In some systems, a single component performs multiple functions. Fuel injection is operated by spraying pressurised fuel into the engine. Therefore a device to pressurise the fuel is needed, such as a fuel pump. The system must determine the appropriate amount of fuel to be supplied and control the fuel flow to supply this amount. Several early mechanical injection systems used relatively sophisticated helix-controlled injection pump(s) that both metered fuel and created injection pressure. Since

480-705: A fuel injection system in 1941 and by 1956 it was used in the Jaguar racing cars. At the 1957 24 Hours of Le Mans , the 1st to 4th placed cars were Jaguar D-Type entries using a Lucas fuel injection system. Also in 1957, General Motors introduced the Rochester Ramjet option, consisting of a fuel injection system for the V8 engine in the Chevrolet Corvette. During the 1960s, fuel injection systems were also produced by Hilborn , SPICA and Kugelfischer . Up until this time,

540-585: A leaked brochure were posted onto the internet in January 2009, detailing the whole E-Class range including the new E 200 CGI and E 230 CGI with direct injected forced induction engines. New features included a blind spot monitor , Lane Keeping Assist , Pre-safe with Attention Assist , and Night View Assist Plus . In the United States the E-Class was priced nearly US$ 4,600 less than the previous model. The W212 estate

600-520: A major update, thanks to the switch to inline six-cylinder engines from the previous V6 engines, along with a new generation of four-cylinder diesel engines, codenamed OM654 , and existing four-cylinder petrol engines. The W213 E-Class is the second-most technologically advanced Mercedes after the new S-Class . The E-Class received the latest in autonomous driving technology for use at highway speeds, capable of piloting itself up to speeds of 130 mph (210 km/h) for up to 2 minutes. The system uses

660-573: A passenger car was released the following year, in the Mercedes-Benz 300SL sports car. However the engine suffered lubrication problems due to petrol diluting the engine oil, and subsequent Mercedes-Benz engines switched to a manifold injection design. Likewise, most petrol injection systems prior to the 2000s used the less-expensive manifold injection design. Throughout the 1950s, several manufacturers introduced their manifold injection systems for petrol engines. Lucas Industries had begun developing

720-477: A pulsed flow system which used an air flow meter to calculate the amount of fuel required. L-Jetronic was widely adopted on European cars during the 1970s and 1980s. As a system that uses electronically-controlled fuel injectors which open and close to control the amount of fuel entering the engine, the L-Jetronic system uses the same basic principles as modern electronic fuel injection (EFI) systems. Prior to 1979,

780-399: A sophisticated common-rail injection system. The latter is the most common system in modern automotive engines. During the 20th century, most petrol engines used either a carburettor or indirect fuel injection. Use of direct injection in petrol engines has become increasingly common in the 21st century. In a common rail system, fuel from the fuel tank is supplied to a common header (called

840-413: Is always intermittent (either sequential or cylinder-individual). This can be done either with a blast of air or hydraulically, with the latter method being more common in automotive engines. Typically, hydraulic direct injection systems spray fuel into the air inside the cylinder or combustion chamber. Direct injection can be achieved with a conventional helix-controlled injection pump, unit injectors, or

900-546: Is called a manifold injection system. There exist two types of manifold injection systems: multi-point injection (or port injection) and single-point injection (or throttle body injection). Internal mixture formation systems can be separated into several different varieties of direct and indirect injection, the most common being the common-rail injection system, a variety of direct injection. The term "electronic fuel injection" refers to any fuel injection system controlled by an engine control unit . The fundamental functions of

It began to appear in the early 1960s, when that feature began to be utilized broadly in the maker's product line, and not just in its upper-tier luxury and sporting models. By

1020-533: Is injected at the same time to all the cylinders; or cylinder-individual , in which the engine control unit can adjust the injection for each cylinder individually. Multi-point injection (also called 'port injection') injects fuel into the intake ports just upstream of each cylinder's intake valve , rather than at a central point within an intake manifold. Typically, multi-point injected systems use multiple fuel injectors, but some systems, such as GM's central port injection system, use tubes with poppet valves fed by

1080-564: Is produced alongside each other in the Bremen plant. The fifth generation E-Class was unveiled at the 2016 North American International Auto Show . This generation E-Class has design cues from the larger W222 S-Class and the smaller W205 C-Class . While the W212 E-Class has tighter surface and harder edges, the new model is curvier and more flowing. Engine options for the W213 E-Class saw

1140-522: Is significant real-world dynamometer testing that indicates the AMG-tuned S model exceeds 600 hp at the flywheel. The coupé (C207) was first shown at the 2009 Geneva Motor Show , while the convertible (A207) was unveiled at the 2010 North American International Auto Show . Both models replaced the previous C209/A209 CLK-Class models. The C207/A207 E-Class is based on the W204 C-Class platform, and

1200-415: The Mercedes-Benz OM 138 ) became available in the late 1930s and early 1940s, being the first fuel-injected engines for passenger car use. In passenger car petrol engines, fuel injection was introduced in the early 1950s and gradually gained prevalence until it had largely replaced carburetors by the early 1990s. The primary difference between carburetion and fuel injection is that fuel injection atomizes

1260-548: The Shvetsov ASh-82FN (M-82FN) . The German direct-injection systems were based on diesel injection systems used by Bosch, Deckel, Junkers and l'Orange. By around 1943, the Rolls-Royce Merlin and Wright R-3350 had switched from traditional carburettors to fuel-injection (called "pressure carburettors" at the time), however these engines used throttle body manifold injection , rather than the direct-injection systems of

1320-475: The Wankel engine . In a manifold injection system, air and fuel are mixed outside the combustion chamber so that a mixture of air and fuel is sucked into the engine. The main types of manifold injections systems are multi-point injection and single-point injection . These systems use either a continuous injection or an intermittent injection design. In a continuous injection system, fuel flows at all times from

1380-669: The accumulator ), and then sent through tubing to the injectors, which inject it into the combustion chamber. The accumulator has a high-pressure relief valve to maintain pressure and return the excess fuel to the fuel tank. The fuel is sprayed with the help of a nozzle that is opened and closed with a solenoid-operated needle valve . Third-generation common rail diesels use piezoelectric injectors for increased precision, with fuel pressures up to 300  MPa or 44,000  psi . The types of common-rail systems include air-guided injection and spray-guided injection . Used by diesel engines, these systems include: This injection method

1440-437: The throttle body . Fuel injectors which also control the metering are called "injection valves", while injectors that perform all three functions are called unit injectors . Direct injection means that the fuel is injected into the main combustion chamber of each cylinder. The air and fuel are mixed only inside the combustion chamber. Therefore, only air is sucked into the engine during the intake stroke. The injection scheme

1500-549: The 1950 Goliath GP700 small saloon, it was also added to the Gutbrod Superior engine in 1952. This mechanically-controlled system was essentially a specially lubricated high-pressure diesel direct-injection pump of the type that is governed by the vacuum behind an intake throttle valve. A Bosch mechanical direct-injection system was also used in the straight-eight used in the 1954 Mercedes-Benz W196 Formula One racing car. The first four-stroke direct-injection petrol engine for

1560-428: The 1954-1959 Mercedes-Benz 300 SL - all used manifold injection (i.e. the injectors located at the intake ports or throttle body, instead of inside the combustion chamber). This began to change when the first mass-produced petrol direct injection system for passenger cars was a common rail system introduced in the 1997 Mitsubishi 6G74 V6 engine. The first common-rail system for a passenger car diesel engine

1620-452: The 1980s, electronic systems have been used to control the metering of fuel. More recent systems use an electronic engine control unit which meters the fuel, controls the ignition timing and controls various other engine functions. The fuel injector is effectively a spray nozzle that performs the final stage in the delivery of fuel into the engine. The injector is located in the combustion chamber , inlet manifold or - less commonly -

1680-647: The E-Class name. E-Class and C-Class coupés and convertibles will be spun off into their own CLE vehicle. Fuel injection engine Fuel injection is the introduction of fuel in an internal combustion engine , most commonly automotive engines , by the means of a fuel injector. This article focuses on fuel injection in reciprocating piston and Wankel rotary engines. All compression-ignition engines (e.g. diesel engines ), and many spark-ignition engines (i.e. petrol (gasoline) engines , such as Otto or Wankel ), use fuel injection of one kind or another. Mass-produced diesel engines for passenger cars (such as

1740-571: The Electrojector system, becoming the first cars known to use an electronic fuel injection (EFI) system. The Electrojector patents were subsequently sold to Bosch, who developed the Electrojector into the Bosch D-Jetronic . The D-Jetronic was produced from 1967-1976 and first used on the VW 1600TL/E . The system was a speed/density system, using engine speed and intake manifold air density to calculate

1800-497: The G10 engine in the 2000 Chevrolet Metro became the last engine available on an American-sold vehicle to use throttle body injection. In indirect-injected diesel engines (as well as Akroyd engines), there are two combustion chambers: the main combustion chamber, and a pre-chamber (also called an ante-chamber) that is connected to the main one. The fuel is injected only into the pre-chamber (where it begins to combust), and not directly into

1860-600: The German engines. From 1940, the Mitsubishi Kinsei 60 series engine used a direct-injection system, along with the related Mitsubishi Kasei engine from 1941. In 1943, a low-pressure fuel injection system was added to the Nakajima Homare Model 23 radial engine. The first mass-produced petrol direct-injection system was developed by Bosch and initially used in small automotive two-stroke petrol engines. Introduced in

1980-582: The S210 wagon. Launched in 2002, the W211 E-Class was another evolution of the previous model. The W211-based C219 CLS-Class 4-door coupe was introduced as a niche model in 2005, primarily to attract a younger demographic. The W211 E-Class was facelifted in June 2006 for the 2007 model year to address quality and technical issues raised by earlier models, Sensotronic was dropped, while Pre-Safe (w/o brake support)

2040-532: The United States. The V8-powered sedans/saloons were named 400 E/500 E from 1990 to 1993, and E 420/E 500 after 1993. Likewise, the 3.0-liter cars (e.g. 300 E) were also re-badged to E 320 with the new 3.2-liter M104 engines and naming rationalization of 1994. For the diesel models, the name change was less elegant, with the 250 D becoming the E 250 Diesel for example. Sedan (W124), Coupé (C124), Convertible (A124), and Estate (S124) body configurations were offered. The W210 E-Class, launched in January 1995, brought

2100-571: The amount of fuel to be injected. In 1974, Bosch introduced the K-Jetronic system, which used a continuous flow of fuel from the injectors (rather than the pulsed flow of the D-Jetronic system). K-Jetronic was a mechanical injection system, using a plunger actuated by the intake manifold pressure which then controlled the fuel flow to the injectors. Also in 1974, Bosch introduced the L-Jetronic system,

2160-553: The big S-Class and the new W110 'Fintail' 190 of 1962. In the 1965 230 model a Straight-6 engine appeared for the first time, and the four-cylinder engine grew in displacement. The midsize Mercedes was redesigned in 1968 as the W114/W115 'Stroke-8' . This time, the 6-cylinder models (The W114s) were most prevalent, with the W115 line making up the bottom of the company's offerings with four- and five-cylinder power. Diesel engines joined

2220-564: The diesel engine, but also improved it. He increased the air blast pressure from 4–5 kp/cm (390–490 kPa) to 65 kp/cm (6,400 kPa). In the meantime, the first manifold injection system was designed by Johannes Spiel in 1884, while working at Hallesche Maschinenfabrik in Germany. In 1891, the British Herbert-Akroyd oil engine became the first engine to use a pressurised fuel injection system. This design, called

2280-411: The electronics in fuel injection systems used analogue electronics for the control system. The Bosch Motronic multi-point fuel injection system (also amongst the first systems where the ignition system is controlled by the same device as the fuel injection system) was the first mass-produced system to use digital electronics . The Ford EEC-III single-point fuel injection system, introduced in 1980,

2340-532: The facelifted W124 in 1993 for the model year 1994 (the W124 was introduced in 1984 but continued with the older naming convention until 1993 when all Mercedes-Benz models switched to a new system, e.g. E 320 instead of 300 E). The diesel versions continued to be the fuel economy option over the four and six-cylinder gasoline engines, and the gasoline V8 engines (available after 1992) increased gasoline power outputs further. Four-cylinder gasoline models were not marketed in

2400-619: The factory. In November 2020, the W213 E-Class was awarded the 2021 Motor Trend Car of the Year award, a first for Mercedes-Benz. The first modern midsize Mercedes was the W120 'Ponton' 180 of 1953 and was produced until 1962. Sharing its engineering with the R121 190 SL of 1955, the Ponton was a stylish sedan with a four-cylinder engine . A larger-engined W121 190 appeared in 1958. Mercedes added tailfins to both

2460-441: The first direct-injected diesel engine for trucks in 1924. Higher pressure diesel injection pumps were introduced by Bosch in 1927. In 1898, German company Deutz AG started producing four-stroke petrol stationary engines with manifold injection. The 1906 Antoinette 8V aircraft engine (the world's first V8 engine) was another early four-stroke engine that used manifold injection. The first petrol engine with direct-injection

2520-631: The fuel injection systems had used a mechanical control system. In 1957, the American Bendix Electrojector system was introduced, which used analogue electronics for the control system. The Electrojector was intended to be available for the Rambler Rebel mid-size car, however reliability problems meant that the fuel injection option was not offered. In 1958, the Chrysler 300D , DeSoto Adventurer , Dodge D-500 and Plymouth Fury offered

2580-572: The fuel injectors, but at a variable flow rate. The most common automotive continuous injection system is the Bosch K-Jetronic system, introduced in 1974 and used until the mid-1990s by various car manufacturers. Intermittent injection systems can be sequential , in which injection is timed to coincide with each cylinder's intake stroke; batched , in which fuel is injected to the cylinders in groups, without precise synchronization to any particular cylinder's intake stroke; simultaneous , in which fuel

2640-633: The fuel through a small nozzle under high pressure, while carburetion relies on suction created by intake air accelerated through a Venturi tube to draw fuel into the airstream. The term "fuel injection" is vague and comprises various distinct systems with fundamentally different functional principles. Typically, the only thing all fuel injection systems have in common is a lack of carburetion . There are two main functional principles of mixture formation systems for internal combustion engines: internal mixture formation and external mixture formation. A fuel injection system that uses external mixture formation

2700-504: The launch of the facelifted W124 in 1993 fuel injection was ubiquitous in Mercedes engines, and the E was adopted as a prefix (i.e., E 220). The model line is referred to officially as the E-Class (or E-Klasse ). All generations of the E-Class have offered either rear-wheel drive or Mercedes' 4Matic four-wheel drive system. The E-Class is Mercedes-Benz' best-selling model, with more than 13 million sold by 2015. The first E-Class series

2760-460: The line firmly into the upper end of the mid-size luxury market. The E-class made major changes compared to the earlier version of the E-class, including four large oval headlights, which gave Mercedes an updated image intended to attract more younger buyers and women. The new E-class was 1.6 in (4.1 cm) longer and 2.3 in (5.8 cm) wider and offered significantly more interior room but

2820-401: The line-up, as did a coupé body. The popular W123 quickly became a best-seller on its launch in 1976. Especially in diesel powered 200D and 240D (also the five-cylinder 300D) guises, the cars enhanced the company's reputation for product quality. Over 2.6 million were produced until the end of production in 1986. Saloon/Sedan, Coupé, and Estate body configurations were offered. The W124

2880-503: The main combustion chamber. Therefore, this principle is called indirect injection. There exist several slightly different indirect injection systems that have similar characteristics. Types of indirect injection used by diesel engines include: In 1872, George Bailey Brayton obtained a patent on an internal combustion engine that used a pneumatic fuel injection system, also invented by Brayton: air-blast injection . In 1894, Rudolf Diesel copied Brayton's air-blast injection system for
