Daimler-Benz DB 602

The Daimler-Benz DB 602, originally known as Daimler-Benz LOF.6, was a German diesel cycle aero engine designed and built in the early 1930s. It was a liquid-cooled upright V16, and powered the two Hindenburg class airships. It has roughly the same displacement and weight of the Beardmore Tornado, which was used in the ill-fated R101, but has almost twice the power of the Tornado, showing Daimler-Benz's superior knowledge regarding diesel engine construction.
