Beginning in 1913, Professor Hugo Junkers of Dessau, Germany made small marine engines and produced diesel engines that powered German U-boats in World War I. He also first produced an aircraft oil engine in 1913. After the war, Junkers produced gasoline powered engines for its own and other aircraft, and later produced both diesel engines and gas turbine engines for aircraft.
In 1933, Junkers began development of the gasoline powered, liquid-cooled, inverted V-12 Jumo 210 and 211, both of which ran in 1936. First tested in a Junkers Ju 87A, 68,000 of the larger Jumo 211 were built during World War II at ratings from 746 to 1,141 kW (1,000 to 1,530 shp), with almost all production versions having direct fuel injection.
The Jumo 211 powered German World War II aircraft such as the Heinkel He 111, Junkers Ju 87 and Ju 88, and Messerschmitt Bf 109.
