Mercedes-Benz M113 engine

The Mercedes-Benz M113 (and similar M155) engine is a gasoline-fueled, spark-ignition internal-combustion V8 automobile engine family used in the 2000s. It is based on the similar M112 V6 introduced in 1997, then later phased out in 2007 for the M156 AMG engine and the M273 engine.

The standard Mercedes-Benz M113s were built in Untertürkheim, Germany, while the AMG versions were assembled at AMG's Affalterbach, Germany plant. M113s have aluminum/silicon (Alusil) engine blocks and aluminum SOHC cylinder heads with two spark plugs per cylinder. The cylinder heads have 3 valves per cylinder (two intake, one exhaust). Other features include sequential fuel injection, iron coated piston skirts, fracture-split forged steel connecting rods, a one-piece cast camshaft, and a magnesium intake manifold.
