Mercedes-Benz W123
The Mercedes-Benz W123 is a range of executive cars produced by German manufacturer Mercedes-Benz from November 1975 to January 1986. The W123 models surpassed their predecessor, the Mercedes-Benz W114, as the most successful Mercedes, selling 2.7 million units before production ended in the autumn of 1985 for the saloon/sedan versions and January 1986 for coupés and estates/station wagons. Following a slow production build-up during the first year, customers who placed their orders faced a lengthy waiting period of nine to twelve months. A black market emerged for the customers who were willing to pay more for immediate delivery. The slightly used W123 commanded about 5,000 Deutsche Mark premium over its original sale price. Like its predecessors, the W123 gained the reputation of being well built and reliable. Many taxi companies chose the W123, and they were a common sight in Germany. Reaching 500,000 or 1,000,000 km with only minor mechanical issues was common with W123 ...

Straight-six Engine
The straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balance, resulting in fewer vibrations than other designs of six or less cylinders. Until the mid-20th century, the straight-six layout was the most common design for engines with six cylinders. However, V6 engines became more common from the 1960s and by the 2000s most straight-six engines had been replaced by V6 engines. An exception to this trend is BMW which has produced automotive straight-six engines from 1933 to the present day. Characteristics In terms of packaging, straight-six engines are almost always narrower than a V6 engine or V8 engine, but longer than straight-four engines, V6s, and most V8s. Straight-six engines are typically produced in displacements ranging from , however engines ranging in size from the Benelli 750 ...

Autocar (magazine)
''Autocar'' (originally ''The Autocar'') is a weekly British automobile magazine published by the Haymarket Media Group. It was first published in 1895 and refers to itself as "the world's oldest car magazine". There are now several international editions, including for China, India, New Zealand, and South Africa. History The publication was launched as ''The Autocar'' by Iliffe and Son Ltd. "in the interests of the mechanically propelled road carriage" on 2 November 1895 when, it is believed, there were only six or seven cars in the United Kingdom. L. J. K. Setright suggests that the magazine was set up by Henry Sturmey as an organ of propaganda for Harry J. Lawson, founder of the Daimler Company and a journalist on the magazine in its early days. Henry Sturmey stood down as editor of ''The Autocar'' magazine and left the company in 1901. ''Autocar'' claims to have invented the road test in 1928 when it analysed the Austin 7 Gordon England Sunshine Saloon. ''Aut ...

Manual Transmission
A manual transmission (MT), also known as manual gearbox, standard transmission (in Canada, the United Kingdom, and the United States), or stick shift (in the United States), is a multi-speed motor vehicle transmission (mechanics), transmission system, where gear changes require the driver to manually select the gears by operating a gear stick and clutch (which is usually a foot pedal for cars or a hand lever for motorcycles). Early automobiles used ''sliding-mesh'' manual transmissions with up to three forward gear ratios. Since the 1950s, ''constant-mesh'' manual transmissions have become increasingly commonplace and the number of forward ratios has increased to 5-speed and 6-speed manual transmissions for current vehicles. The alternative to a manual transmission is an automatic transmission; common types of automatic transmissions are the Automatic transmission#Hydraulic automatic transmissions, hydraulic automatic transmission (AT), and the continuously variable transmissio ...

4G-TRONIC
The Mercedes-Benz 4G-Tronic transmission was produced from 1979 to 1996 in W4A 028, W4A 040 (both type 722.3), W4A 020 (type 722.4), and W5A 030 (type 722.5) variants. Abstract The 4G-Tronic transmission is a hydraulically operated four speed automatic without lock-up that replaced the similarly designed W3A 040, W3B 050, and W4B 025 family of automatic transmissions with the introduction of the W126 S-Class in 1979. In some models it is calibrated to move off in second gear to reduce "creeping" and provide a smoother ride, selecting 1st only if the selector is in "2" or in case of abrupt acceleration. Other calibrations have the transmission rest in 2nd gear and kick down to 1st as soon as the accelerator is touched but before the throttle is opened. In some V8 installations a small control unit activates the kick down solenoid when the brake pedal is released so that the car moves off in 1st gear. Other attributes of this transmission include ...

Turbodiesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. ...

Straight-five Engine
The straight-five engine (also referred to as an inline-five engine; abbreviated I5 or L5) is a piston engine with five cylinders mounted in a straight line along the crankshaft. Although less common than straight-four engines and straight-six engines, straight-five engines have occasionally been used by automobile manufacturers since the late 1930s, particularly the Mercedes Benz's diesel engines from 1974 to 2006 and Audi's petrol engines from 1979 to the present. Straight-five engines are smoother running than straight-four engines and shorter than straight-six engines. However, achieving consistent fuelling across all cylinders was problematic prior to the adoption of fuel injection. Characteristics Straight-five engines are typically shorter than straight-six engines, making them easier to fit transversely in an engine bay. They are also smoother than straight-four engines, and are narrower than V engines and flat engines. Engine balance and vibration Five-cylinder e ...

Mercedes-Benz OM617
The OM617 engine family is a straight-5 Diesel engine, diesel automobile engine from Mercedes-Benz used in the 1970s and 1980s. It is a direct development from the straight-4 Mercedes-Benz OM616, OM616. It was sold in vehicles from 1974 to 1991. The OM617 is considered to be one of the most reliable engines ever produced with engines often reaching over without being rebuilt and is one of the key reasons for Mercedes' popularity in North America in the 1980s, as it was powerful and reliable compared to other automotive diesels of the time. It is also a very popular choice for the use of alternative fuels, mainly straight or waste vegetable oil fuel, vegetable oil and biodiesel, although the use of these fuels may cause engine damage over time if not processed properly before use. OM617 Naturally Aspirated Essentially an OM616 with an extra cylinder, it debuted in 1974 with the W115(240 3.0d) chassis. Bore and stroke was . It was originally .

Mercedes-Benz OM616
The OM616 engine family is a diesel automobile Inline-four engine from Mercedes-Benz used in the 1970s and 1980s, and produced by Force Motors in India from the 1980s to the present. This engine was used in various cars, vans and Unimogs over its production lifetime, and still finds use in Force Motors SUVs. The abbreviation ¨OM¨ stands for ¨Oel-Motor¨ (Oil Motor), which refers to the fact that it runs on oil. This method of naming is still used on Mercedes-Benz diesel engines today. Power update The OM616 was a engine with power output of . In August 1978 the precombustion chamber was updated for more swirl and more efficient combustion. The new camshaft pushes the valves deeper so the air and exhaust gases have less resistance. The engine capacity was lowered to to satisfy engine displacement tax laws in Europe, but power output rose to . A similar technique power update around these time was also done on the OM615 and OM617. Applications * OM616.912 ** 1976-1978 ...
