The M113 E50 engine is an unusually lightweight, compact engine (unlike its predecessor M119) was a continuation of the line of three-valve M112 engines. The engineers added two more to the six cylinders and got the M113. Due to its compactness, it was installed on all rear- and all-wheel drive Mercedes models. Each cylinder has three valves (two inlet and one outlet), and in the M113 engine, the area of the outlet valve is 30% less than the total area of the two outlet valves in its predecessor, in addition, it has less weight (the rod is filled with sodium).
