Mercedes-Benz M138 Engine
The Mercedes-Benz M137 engine was a naturally aspirated, SOHC 60° V12 engine, with three valves per cylinder. It was built to replace the larger and heavier, yet more powerful, DOHC, four valves per cylinder, naturally aspirated, 6.0 L M120 V12 unit. The M137 was used briefly between 1998 and 2002 for the W220 S-Class and C215 CL-Class. The architecture was similar to M112 and M113 engines and was designed to match the overall dimensions of a V8 unit with an undersquare internal measurements. The crankcase was cast in a lightweight alloy with "Silitec" (silicon/aluminium) cylinder liners to save weight. The new powerplant was 80 kg lighter than its predecessor and offered better fuel consumption thanks to a cylinder deactivation technology. Both displacement variants have 10:1 compression ratio. The M137 was replaced by the more powerful twin-turbocharged M275 engine. E58 Mercedes introduced M137 engine in its 5.8-litre form in S 600 and CL 600 models. The internal me ...

Mercedes-Benz CL-Class
The Mercedes-Benz CL-Class is a line of grand tourers which was produced by German automaker Mercedes-Benz, produced from 1992 to 2014. The name CL stands for the German Coupé Leicht (Coupé-Light) or Coupé Luxusklasse (Coupé-Luxury). It is considered by Mercedes as their premier model. In 2015 Mercedes officially ceased using the CL-Class designation, returning the vehicle's name back to the S-Class Coupe/Convertible, replacing it with the C217 S-Class Coupé. History The CL-Class is the coupé derivative of the S-Class full-size luxury saloon, upon which it shares the same platform. Formerly known as the SEC (Sonderklasse-Einspritzmotor-Coupé) and later S-Coupé, it was spun off into its own, separate name in 1996 and in 1997 for North American markets. The CL continued to follow the same development cycle as the S, though riding on a shorter wheelbase, and sharing the same engines albeit with less choice as only the higher-output powertrains are offered. The las ...

Mercedes-Benz G-Class
The Mercedes-Benz G-Class, sometimes colloquially called the G-Wagen (as an abbreviation of Geländewagen) is a four-wheel drive automobile manufactured by Magna Steyr (formerly Steyr-Daimler-Puch) in Austria and sold by Mercedes-Benz. Originally developed as a military jeep, military off-roader, later more luxury car, luxurious models were added to the line. In certain markets, it has been sold under the Puch name as Puch G until 2000. The G-Wagen is characterised by its boxy styling and body-on-frame construction. It uses three fully locking differentials, one of the few passenger car vehicles to have such a feature. Despite the introduction of an intended replacement, the unibody SUV Mercedes-Benz GL-Class in 2006, the G-Class is still in production and is one of the longest-produced vehicles in Daimler's history, with a span of years. Only the Unimog surpasses it. In 2018, Mercedes-Benz launched a technically new second generation, still with only minor design changes. The ...

Twin-turbocharged
Twin-turbo (not to be confused with a twincharger setup, which is a combination of a supercharger and a turbocharger) refers to an engine in which two turbochargers work in tandem to compress the intake fuel/air mixture (or intake air, in the case of a direct-injection engine). The most common layout features two identical or mirrored turbochargers in parallel, each processing half of a V engine's produced exhaust through independent piping. The two turbochargers can either be matching or different sizes. Types and combinations There are three types of turbine setups used for twin-turbo setups: * Parallel * Sequential * Series These can be applied to any of the five types of compressor setups (which theoretically could have 15 different setups): * Compound Compressors * Staged Compound Compressors * Staged Sequential Compressors * Parallel Sequential Compressors * Parallel Compressors Parallel A parallel configuration refers to using two equally-sized turbochargers whic ...

Undersquare
In a reciprocating piston engine, the stroke ratio, defined by either bore/stroke ratio or stroke/bore ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length. This can be used for either an internal combustion engine, where the fuel is burned within the cylinders of the engine, or external combustion engine, such as a steam engine, where the combustion of the fuel takes place ''outside'' the working cylinders of the engine. A fairly comprehensive yet understandable study of stroke/bore effects was published in ''Horseless Age'', 1916. Conventions In a piston engine, there are two different ways of describing the ''stroke ratio'' of its cylinders, namely: ''bore/stroke'' ratio, and ''stroke/bore'' ratio. Bore/stroke ratio Bore/stroke is the more commonly used term, with usage in North America, Europe, United Kingdom, Asia, and Australia. The diameter of the cylinder bore is divided by the length of the piston stroke to give the ratio. ...

Mercedes-Benz M112 Engine
The Mercedes-Benz M112 engine is a gasoline-fueled, 4-stroke, spark-ignition, internal-combustion automobile piston V6 engine family used in the 2000s. Introduced in 1998, it was the first V6 engine ever built by Mercedes. A short time later the related M113 V8 was introduced. All are built in Bad Cannstatt, Germany except the supercharged C32 AMG, which is assembled in Affalterbach, Germany. All M112 engines have silicon/aluminum (Alusil) engine blocks with a 90° vee angle. The aluminum SOHC cylinder heads have 3 valves per cylinder. All use sequential fuel injection with two spark plugs per cylinder. All have forged steel connecting rods, a one-piece cast camshaft, iron-coated aluminum pistons and a magnesium intake manifold. To deal with the vibration problems of a 90 degree V6, a balancer shaft was installed in the engine block between the cylinder banks. This essentially eliminated first and second order vibration problems (see engine balance). A dual-length Variable ...

Mercedes-Benz W220
The Mercedes-Benz W220 was a range of flagship sedans which, as the fourth generation Mercedes-Benz S-Class, replaced the W140 S-Class after model year 1998 — with long and short wheelbase versions, performance and luxury options; available four-wheel drive; and a range of diesel as well as gas/petrol V6, V8, and V12 engines. Compared to its predecessor, the W220 had somewhat smaller exterior dimensions but offered greater interior volume, particularly in the long-wheelbase versions, and slightly less cargo volume. Development began in 1992, with the final design, under the direction of Steve Mattin, approved in June 1995 and frozen in March 1996. The completed prototypes were presented in June 1998. W220 production began on August 13, 1998, and C215 coupé production followed in 1999. Production of the 220-series totalled 484,683 units, slightly more than the production totals from the W140. Production ended in late 2005, when the W220 was replaced by the W221 S-Class ...
