The Mercedes Benz M136 engine[1] was a 1697cc otto-cycle (gasoline) inline-four engine introduced by Mercedes-Benz in 1935 for its new W136 sedan. It was initially used in the W136 170 V.
It was enlarged to 1767cc in 1950 and installed in the W191 170 S variants, and remained in production until 1955, when it was replaced by the 1.9-litre single overhead camshaft inline-4 M121.
