mercedes-benz m112-e24

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 1996, it was the first gasoline 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 C 32 AMG and SLK 32 AMG, assembled in Affalterbach, Germany.
All M112 engines have silicon/aluminum 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. A dual-length Variable Length Intake Manifold is fitted to optimise engine flexibility....
