The M115 engine family was a straight-4 automobile engine from Mercedes-Benz that was produced during the 1970s. This engine was a successor from the M121 and was replaced by the M102 engine. This engine is modified from the M121 by adding a five-bearing crankshaft.[2] The same engine was produced in several versions with differing volume, compression, and horse power according to its application.
The M115.920 is a engine with a power output NaN0NaN0. The cylinder bore on this type is 87 mm and piston stroke is 92.4 mm. This type shares the crankshaft with OM615 220D.
