In an internal combustion engine , the engine block is the structure that contains the cylinders and other components. The engine block in an early automotive engine consisted of just the cylinder block, to which a separate crankcase was attached. Modern engine blocks typically have the crankcase integrated with the cylinder block as a single component. Engine blocks often also include elements such as coolant passages and oil galleries.
30-612: The Rison Texaco Service Station is a historic automobile service station at 216 Main Street (corner of Third Street) in Rison, Arkansas . It is a distinctive Art Deco structure built c. 1926. Since 1990 it has housed a timber company. The building was listed on the National Register of Historic Places in 2002.

60-553: A focus on basic procedures, labor is often performed by entry-level technicians which simplifies the business overhead resulting in a less expensive service as compared to a traditional automotive workshop. In the United States, new car dealerships have service departments that are certified by their respective OEM (Original Equipment Manufacturer) to perform warranty and recall repairs. Customer-pay repairs can also be completed, however most service departments tend to only work on
90-587: A large inventory of tires and aftermarket wheels, some of which may be on display while others require special ordering. In addition to parts, common labor services include tire rotation, balancing and repair as well as wheel alignment which can prevent premature tire wear. In the Philippines , roadside tire repair shops are called vulcanizing shops in Philippine English . They specialize in quickly and cheaply repairing flat tires by patching punctures with
120-647: A monobloc design where the cylinder head, block, and half of the crankcase share the same casting. Apart from cost, one reason for this is to produce an overall lower engine height. The primary disadvantage can be that repairs become more time-consuming and impractical. An example of engines with integrated cylinder heads are the Honda GC -series and GXV-series engines, which are sometimes called "Uniblock" by Honda. Several cars with transverse engines have used an engine block consisting of an integrated transmission and crankcase. Cars that have used this arrangement include
150-631: A monobloc design with one block for all cylinders plus an integrated crankcase. In such cases, the skirts of the cylinder banks form a crankcase area of sorts, which is still often called a crankcase despite no longer being a discrete part. Using steel cylinder liners and bearing shells minimizes the effect of the relative softness of aluminium. Some engine designs use plasma transferred wire arc thermal spraying , instead of cylinder sleeves, to further reduce weight. These types of engines can also be made of compacted graphite iron , such as in some diesel engines. Some modern consumer-grade small engines use
180-550: A rubber compound patch. A muffler shop, also called an exhaust shop, is a business model that concentrates solely on the engine exhaust system . These facilities utilize large tubing benders which allow a technician to fabricate a new exhaust system out of otherwise straight lengths of pipe. Welding is often necessary in this line of work. Automotive repair shops that specialize in bodywork repair are known as body shops. Auto body technicians can perform paintwork repairs to scratches, scuffs and dents, as well as repairs to
210-412: A separate crankcase. As casting techniques improved, an entire cylinder block of 4, 6, or 8 cylinders could be produced in one piece. This monobloc construction was more straightforward and more cost-effective to produce. All the cylinders and crankcase could be made in a single component for straight engine cylinder layouts. One of the early engines produced using this method is the 4-cylinder engine in
240-595: Is dedicated to repairing and maintaining a particular group of vehicles is called a fleet shop. Common examples of a fleet include taxi cabs , police cars , mail trucks and rental vehicles . Similar to a lubrication/safety shop, a fleet shop focuses primarily on preventative maintenance and safety inspections, and will often outsource larger or more complex repairs to another repair facility. Shops that specialize in cylinder head and cylinder block machining are called engine machine shops . These facilities utilize large electromechanical machines that are not found in
270-659: Is often caused by hail , stones, wild animals, fallen trees, automobile theft and vandalism . Mobile mechanics provide doorstep repair services and home delivery of new and used auto parts of different late model and classic cars whose parts are not widely available in the market. In countries such as the UK, the mobile car body repair sectors has experienced high growth by way of mobile SMART Repair companies providing mobile car body repair services, such as Bumper Repairs, auto body repair, paintless dent repair and paintwork defect repairs to private and commercial consumers, typically within
300-455: Is rather common for a dealership technician to start this type of competing business after leaving the employment of a new car dealership. Independent automobile repair shops in the US may also achieve OEM certification through manufacturer sponsored programs. European Union law (The EC Block Exemption Regulation 1400/2002 (October 2003 )) permits motorists more flexibility in selecting where their car
330-417: Is serviced. Maintenance and service work does not have to be done by the dealership providing that the independent garage uses Original Equipment 'Matching Quality' parts and follows the manufacturer's service schedules. The Block Exemption Regulation (BER) covers service and maintenance during the warranty period and prohibits vehicle manufacturers' warranties from including restrictive conditions. A shop that

#1732898407578360-461: The Ford Model T , introduced in 1908. The technique spread to straight-six engines and was commonly used by the mid-1920s. Up until the 1930s, most V engines retained a separate block casting for each cylinder bank, with both bolted onto a common crankcase (itself a separate casting). For economy, some engines were designed to use identical castings for each bank, left and right. A rare exception
390-429: The crankshaft . As with cylinder blocks, this is primarily an integrated component in modern engines. Engine blocks are typically cast from either cast iron or an aluminium alloy . Aluminium blocks are much lighter and transfer heat more effectively to coolant, but iron blocks retain some advantages, such as durability and reduced thermal expansion . Weight reductions through material selection . Presently, most of
420-440: The cylinders , coolant passages, oil galleries, crankcase, and cylinder head(s) . The first production engines of the 1880s to 1920s usually used separate components for each element, which were bolted together during engine assembly. Modern engines, however, often combine many elements into a single component to reduce production costs. The evolution from separate components to monobloc engine blocks has gradually progressed since
450-527: The 1966-1973 Lamborghini Miura and cars using the BMC A-series and E-series engines. This design often results in the engine and transmission sharing the same oil. Motorcycles such as the Honda CB750 use a similar layout, with the cylinder block and crankcase integrated with part of the transmission. Many farm tractor designs integrate the cylinder block, crankcase, transmission, and rear axle into
480-563: The National Register of Historic Places is a stub . You can help Misplaced Pages by expanding it . Automobile repair shop An automobile repair shop (also known regionally as a garage or a workshop ) is an establishment where automobiles are repaired by auto mechanics and technicians . The customer interface is typically a service advisor , traditionally called a service writer. Automotive garages and repair shops can be divided into following categories: First appearing in
510-400: The average automotive repair shop. In the US, engine machining is typically performed by an ASE certified machinist in order to correct worn or damaged engine components as an alternative to component replacement. Performance engine building is another popular service frequently offered by this type of workshop. Some repair shops specialize in tires and wheels. These businesses usually have
540-400: The backbone of the cylinder wall. Additional sleeves are inserted within, which remain "dry" outside, surrounded by the block's material. For either wet or dry liner designs, the liners (or sleeves) can be replaced, potentially allowing an engine overhaul or rebuild without replacing the block itself. However, there are more practical repair options. The crankcase is the structure that houses
570-413: The bodies of vehicles damaged by collisions . Many body shops now offer paintless dent repair and auto glass replacement. Automotive repair shops that specialize in auto glass repair are known as auto glass repair shops. They offer auto glass repairs to chips, cracks and shattered glass. The types of glass they repair include windshields , car windows, quarter glass and rear windows. This type of damage
600-461: The earliest decades of internal combustion engine development, cylinders were usually cast individually, so cylinder blocks were usually produced separately for each cylinder. Following that, engines began to combine two or three cylinders into a single-cylinder block, with an engine combining several of these cylinder blocks. In early engines with multiple cylinder banks – such as V6 , V8 , or flat-6 engines – each bank
630-604: The early 1900s, many filling stations offered vehicle repair services as part of their full service operation. This once popular trend has declined significantly over the years as many locations found it more profitable to exchange vehicle service bays for grocery isles, which ultimately led to the emergence of the quick oil change industry. Commonly referred to as a quick lube or express service shop, this type of facility specializes in preventive maintenance and safety inspections rather than repairs. Product sales are typically limited to automotive fluids, belts and hoses. With

#1732898407578660-442: The early 20th century. The integration of elements has relied on the development of foundry and machining techniques. For example, a practical, low-cost V8 engine was not feasible until Ford developed the methods used to build its flathead V8 engine . Other manufacturers then applied those techniques to their engines. A cylinder block is a structure that contains the cylinder , plus any cylinder sleeves and coolant passages. In
690-676: The engine block, taking into account the particular needs of the material. An engine where all the cylinders share a common block is called a monobloc engine . Most modern engines use a monobloc design, and few have a separate block for each cylinder. This has led to the term "engine block," which usually implies a monobloc design, with "monobloc" rarely used. In the early years of the internal combustion engine, casting technology couldn't produce large castings with complex internal cores (for water jackets etc). Most early engines, particularly those with more than four cylinders, had their cylinders cast as pairs or triplets of cylinders, then bolted to
720-438: The engine blocks in mass production are gray castings. Reducing weight has resulted in using aluminum-silicon alloys more frequently for the engine block in small-displacement engines. Engine blocks of comparable design, but using Al-Si alloys, are not lighter than cast iron engine blocks in the same ratio as that for the specific weights of the materials. In engine blocks made of gray cast iron, weight can be reduced by optimizing
750-416: The engine's coolant. In other words, the liner is the entire cylinder wall, rather than merely a sleeve. The advantages of wet liners are a lower mass, reduced space requirements, and coolant being heated faster from a cold start, reducing start-up fuel consumption and heating the car cabin sooner. Dry liner cylinder blocks use either the block's material or a discrete liner inserted into the block to form
780-462: The industry framework of refinishing vehicle damage on a localised basis, where the area of damage being repaired is not in excess of an A4 sheet of paper. Engine block The term "cylinder block" is often used interchangeably with "engine block". However, technically, the block of a modern engine (i.e., multiple cylinders integrated with another component) would be classified as a monobloc . The main structure of an engine typically consists of
810-463: The structure and thin-wall casting. With this casting technique, a wall thickness of as little as about 3 mm is generally possible. In comparison, the walls of cast iron engine blocks are usually from 4.0 to 5.5 mm thick. Using vermicular graphite cast iron (GGV), a casting material with great strength, enables weight reductions by about 30% compared to conventional casting materials such as GG 25. Weight reduction, to this extent, requires engineering for
840-525: The vehicle brand of which they are a dealer. Dealership technicians must complete additional training provided by the OEM, and in doing so become specialized and certified for that particular vehicle make. Independent auto repair shops are businesses that are independently owned and operated. In states regulating a smog or emission test, often, independent auto repair shops offer these tests as well. These may also include regional or national chains and franchises. It
870-761: Was the Lancia 22½° narrow-angle V12 of 1919, which used a single block casting combining both banks. The Ford flathead V8 – introduced in 1932 – represented a significant development in the production of affordable V engines. It was the first V8 engine with a single-engine block casting, putting a V8 into an affordable car for the first time. The communal water jacket of monobloc designs permitted closer spacing between cylinders. The monobloc design approach also improved engines' torsional rigidity as cylinder numbers, engine lengths, and power ratings increased. Most engine blocks today, except some unusual V or radial engines and large marine engines, use
900-405: Was typically made of one or multiple separate cylinder blocks. Since the 1930s, mass production methods have developed to allow both banks of cylinders to be integrated into the same cylinder block. Wet liner cylinder blocks use cylinder walls that are entirely removable and fit into the block using special gaskets. They are called "wet liners" because their outer sides come in direct contact with
