Mercedes-Benz OM603
The OM603 engine was a straight-6 Diesel automobile engine from Mercedes-Benz used from 1984 through 1999. The 603 saw limited use in the W124, W126 and W140 model vehicles. It is closely related to the 4 cylinder OM601 and the 5 cylinder OM602 engine families of the same era. The 603.96 engine has a capacity of and was a development of the reliable 5 cylinder OM617 engine. It produced 143 hp at 4600 rpm (euro market without catalytic converter produced 148hp) and 195 ft.lb at 2400 rpm with a compression ratio of 22.0:1. Versions 603.96x and 603.97x are turbocharged. Only turbocharged models of the 603 series were available to the U.S. market. The single camshaft and injection pump are driven by duplex chain from the crankshaft. A separate single row chain drives the oil pump. The camshaft operated the valves via hydraulic bucket tappets; valve clearance adjustment is automatic. Fuel is injected into a pre-combustion chamber. A Bosch M in-line injection pump is used, w ...

Mercedes-Benz W124
The Mercedes-Benz W124 is a range of mid-size cars made by Daimler-Benz from 1984 to 1997. The range included numerous body configurations, and though collectively referred to as the W-124, official internal chassis designations varied by body style: saloon (W 124); estate (S 124); coupé (C 124); cabriolet (A 124); limousine (V 124); rolling chassis (F 124); and long-wheelbase rolling chassis (VF 124).

Mercedes-Benz OM617 Engine
The OM617 engine family is a straight-5 diesel automobile engine from Mercedes-Benz used in the 1970s and 1980s. It is a direct development from the straight-4 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 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 . Bosch MW inline injection pumps were used, which had flyweight governors and vacuum shutoff. ...

Straight-5
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 OM601 Engine
The Mercedes-Benz OM601 engine is a 4 cylinder diesel automobile engine that was manufactured by Mercedes-Benz. Three variants of the engine were built: a model, a version built for the US market, and a for commercial vehicles. The first two were rated by the manufacturer for at 4200 RPM and of torque at 2800 RPM; the increase in displacement reduced emissions in order to meet US automobile emissions requirements. The commercial vehicle version had in standard variants, the turbocharged version (OM601.970) in the V230 TD and Vito 110D had . It is closely related to the 5 cylinder OM602 and the 6 cylinder OM603 engine families of the same era. The OM601 was built with an aluminum head on an iron block. The camshafts and fuel injection pump are driven by a duplex chain from the crankshaft. A separate single row chain drives the oil pump from the crankshaft. Fuel supply is indirect injection via a prechamber arrangement. The OM-601's injection pump is a mechani ...

Straight-4
A straight-four engine (also called an inline-four) is a four-cylinder piston engine where cylinders are arranged in a line along a common crankshaft. The vast majority of automotive four-cylinder engines use a straight-four layout (with the exceptions of the flat-four engines produced by Subaru and Porsche) and the layout is also very common in motorcycles and other machinery. Therefore the term "four-cylinder engine" is usually synonymous with straight-four engines. When a straight-four engine is installed at an inclined angle (instead of with the cylinders oriented vertically), it is sometimes called a slant-four. Between 2005 and 2008, the proportion of new vehicles sold in the United States with four-cylinder engines rose from 30% to 47%. By the 2020 model year, the share for light-duty vehicles had risen to 59%. Design A four-stroke straight-four engine always has a cylinder on its power stroke, unlike engines with fewer cylinders where there is no power stroke occu ...

Mercedes-Benz W140
The Mercedes-Benz W140 is a series of flagship vehicles manufactured by Mercedes-Benz from 1991 to 1998 in sedan/saloon and coupe body styles and two wheelbase lengths (SE and SEL). Mercedes-Benz unveiled the W140 S-Class at Geneva Motor Show in March 1991 with sales launch in April 1991 and North American launch on 6 August 1991. All models were renamed in June 1993 as part of the corporate-wide nomenclature changes for 1994 model year on, becoming S regardless of wheelbase length or body style as well as fuel type. Diesel models carried a TURBODIESEL trunk/boot lid label. In 1996, the S-Class coupé was renamed again as CL-Class into its own model range. The W140 series S-Class was superseded by the W220 S-Class sedan and C215 CL-Class coupé in 1998 after an eight-year production run. Production of the W140 reached 432,732, with 406,710 sedans and 26,022 coupés. History The development on the W140 began in 1981, with official introduction originally set in September ...

Mercedes-Benz W126
The Mercedes-Benz W126 is the company's internal designation for its second generation S-Class, manufactured in sedan/saloon (1979–1991) and coupé (1981–1990) models, succeeding the company's W116 range. Mercedes introduced the 2-door C126 coupé model, marketed as the SEC, in September 1981. This generation was the first S-Class to have separate chassis codes for standard and long wheelbases (W126 and V126) and for coupé (C126). The long 12-year production (1979–1991) resulted in 818,063 sedans/saloons and 74,060 coupés being built, totalling 892,123. W126 is so far the most successful and the longest in production for S-Class. History After the debut of W116 S-Class in 1972, Mercedes-Benz began preparing for the next generation S-Class in October 1973. The project, code-named "Project W126", aimed to provide an improved ride, better handling, and improved fuel efficiency. The oil crisis of 1973 and increasingly stringent emission and safety regulations in the Uni ...
