Collection Item Summary:

Junkers produced diesel engines that powered German U-boats in World War I, and 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 Jumo 210 and 211, both of which ran in 1936. These were liquid-cooled, inverted V-12s. The 210 began at 447 kW (600 shp) and reached 544 kW (730 shp) in the 210 Ga fitted to the Messerschmitt Bf 109C. The larger 211 was first tested in a Junkers Ju 87A, and 68,000 were built during World War II at ratings from 746 to 1,141 kW (1,000 to 1,530 shp), almost all production versions having direct fuel injection.

The Jumo 210 Da/Ea engines powered versions of the Heinkel He 112, Junkers Ju 87, and Messerschmitt Me 109 and Me 110 aircraft.
