The Daimler-Benz DB 600 was a German aircraft engine designed and built before World War II as part of a new generation of German engine technology. It was a liquid-cooled inverted V12 engine, and powered the Messerschmitt Bf 110 and Heinkel He 111 among others. Most newer DB engine designs used in WW2 were based on this engine. The decision by the RLM to concentrate on manufacturing aircraft engines using fuel injection systems rather than carburettors meant that the DB 600 was quickly superseded by the otherwise similar DB 601. Later DB series engines grew in bore, stroke, and horsepower, including the DB 603 and DB 605, but were generally similar to the pattern created with the DB 600.
