Engine Mercedes M111 E20/E20 ML

Back in 1992, the outdated 4-cylinder E20 engine from the M102 engine series was replaced by the M111 series engines. The new M111 line includes such legendary engines as M111E18, M111E22 and M111E23. The new 2.0-liter engine differed from its predecessor first of all: a completely new cylinder block, which was made of cast iron, a new crankshaft, as well as a new connecting rod and piston group. On the M111 E20 engine, the cylinder head had 4 valves per cylinder and two camshafts. The design provided for a place for hydraulic lifters, as well as an electronic fuel injection system.
