Two Soviet-built diesel engines MAN design

The VM or BM (Cyrillic script) was an experimental Soviet diesel-electric locomotive named after Vyacheslav Molotov (Russian: Вячеслав Молотов). It was a two-unit machine of 2-Do-1+1-Do-2 wheel arrangement and only one pair of locomotives was built.

Powertrain

The two diesel engines were of the six cylinder, four stroke type. They were Soviet-built and based on the MAN engine used in the Soviet E el-5 locomotive. The MAN engine was rated at 1,200 hp at 450 rpm but the Soviet engines were de-rated to 1,050 hp at 400 rpm. The traction motors were similar to those used in the Soviet E el-12 locomotive but the rating of each motor was increased from 140 kW to 154 kW.
