Which army used diesel engines in their tanks during the WW2?
Germans
British
Americans
Soviets
At that time, most of the armies used lighter and more efficient petrol engines, often taken from the aviation industry. Soviets, however decided to mass-produce diesel engines. There were several reasons: diesel fuel was less flammable and therefore safer, the Soviet Union had the huge aluminium forge capacity, and they didn't have large diesel-consuming fleet.
