Daimler-Benz DB 601
The Daimler- Benz DB 601 was a liquid-cooled, twelve-cylinder aircraft engine with 33.9 liters of displacement and direct fuel injection, which was used in many German military and record aircraft. It was developed at Daimler -Benz from 1934 from the same displacement petrol engine DB 600.
Daimler -Benz and various contractors established in the German Empire 1937-1943 a total of 19,180 pieces here. As a licensed construction of the DB 601 was manufactured in the Confederate Axis powers Italy and Japan.
History
Under the leadership of Hans Scherenberg was brought by Daimler- Benz in Stuttgart in cooperation with Robert Bosch GmbH, the conversion of the DB 600 on gasoline injection to production stage. After the first successful trial runs in 1935 the production of the DB began 601 in November 1937. The engine was until 1943 the Daimler - Benz plant in Berlin -Marie Felde, the Daimler -Benz Motoren GmbH in gene Hagen, Lower Saxony engine works ( NIEMO ) in Braunschweig - Querum and at the Henschel aircraft engines GmbH made in Altenbauna near Kassel.
In 1940, amounted to plant gene Hagen at a production time of 2820 hours, the cost of a motor 29,200 Reichsmarks, which corresponds, according to current currency and inflation-adjusted price of 115,900 euros.
The DB 601 was in German combat aircraft such as the Messerschmitt Bf 109 E and F, Bf 110 C to F, Messerschmitt Me 210, Heinkel He 100, Heinkel He 111 P, Dornier Do 215 and Fieseler Fi 167 used.
Licenses for reproduction were awarded to Alfa Romeo, Fiat, Aichi and Kawasaki. The DB 601 was one of the most reliable and robust German aircraft engines of World War II.

Versions
- DB 601 A-1 - Standard Version, 1100hp take-off power (1 min, increased short output) or 990 hp ( 5 min, short power) DB 601 B- 1 - Version for two-engined aircraft such as the Bf 110, reduced propeller speed
- DB 601 Ba - version for twin-engine aircraft such as the Bf 110, reduced propeller speed
- DB 601 P - version for twin-engine aircraft such as the Bf 110, reduced propeller speed
- DB 601 F - version for twin-engine aircraft such as the Bf 110, reduced propeller speed
- DB 601 G - version for slow multi-engine aircraft such as bombers, further reduced propeller speed
Note: All performance data for sea level. For a period of 1 min increased short performance was generally available only in bombers and fighter-bombers to allow start with overload. Short power or starting and emergency power was present in all machines, if not locked. DB 601 N and E along with variants were initially only for climb and combat power (1020 or 1200 hp ) enabled.
