Klöckner-Humboldt-Deutz DZ 710

The Klöckner-Humboldt-Deutz DZ 710 was a German aircraft engine manufactured by Motorenfabrik Oberursel A.G. in the early 1940s. It was a 16-cylinder horizontally-opposed, two cycle diesel engine. A larger 32-cylinder variant, the Klöckner-Humboldt-Deutz DZ 720 was basically two DZ 710's 'bolted' together to make an H engine configuration.
