High Quality Content by WIKIPEDIA articles! The Jumo 211 was an inverted V-12 aircraft engine, Junkers Motoren`s primary aircraft engine of World War II. It was the direct competitor to the famous Daimler-Benz DB 601 and closely paralleled its development. While the Daimler-Benz engine was mostly used in single-engined and twin-engined fighters, the Jumo engine was primarily used in bombers such as Junkers` own Ju 87 and Ju 88.
