Daimler-Benz DB 605
The Daimler-Benz DB 605 was a German aircraft engine, built during World War II. Developed from the Daimler-Benz DB 601 first produced in 1938, the DB 605 was used mainly in Messerschmitt Bf 109 and Bf 110 fighters. The inverted mounting of the cylinders provided better visibility for the pilot, a lower center of gravity, and improved access for maintenance.
