Summary
Dr. Hugo Junkers started development of two-stroke cycle diesel aircraft engines in 1911 at a small factory at Dessau, Germany. His diesel engines powered German U-boats in World War I, and he first produced an aircraft oil engine in 1913. After the war, Junkers produced gasoline powered engines for its own and other aircraft.
Development of the liquid-cooled, inverted V-12 Jumo 210 and 211 began in 1933. The 210 began at 447 kW (600 shp) and reached 544 kW (730 shp) in the 210 Ga fitted to the Messerschmitt Bf 109C. First tested in a Junkers Ju 87, 68,000 of the larger 211 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 211 powered German World War II aircraft such as the Heinkel He 111, Junkers Ju 87 and Ju 88, and Messerschmitt Bf 109.
