Mercedes-Benz M111 engine

The Mercedes-Benz M111 is a family of four-cylinder engines built by Mercedes-Benz from 1992 to 2003. It used the cylinder block of the single overhead camshaft M102 but added a twin overhead camshaft head with four valves per cylinder, a layout the article credits to Cosworth, together with variable valve timing and electronic fuel injection and ignition management in place of the mechanical KE-Jetronic system. It was introduced in summer 1992 for the W124 and became the main Mercedes-Benz engine of the 1990s and early 2000s. A supercharged Kompressor version arrived in 1996, and besides Mercedes-Benz cars and commercial vehicles the engine also powered several Volkswagen and Ssangyong models.
