(Specifications for DB 601Aa) Manufacturer: Daimler-Benz Type: Supercharged 60° inverted Vee piston engine Cylinders: 12 Bore: 150 mm (5.91 in) Stroke: 160 mm (6.30 in) Displacement: 33.9 L (2,070 in³) Length: 1,722 mm (68 in) Dry weight: 590 kg (1,320 lb) Components: – Valvetrain: Two intake and two sodium-cooled exhaust valves per cylinder actuated via a single overhead camshaft per cylinder block. – Supercharger: Gear-driven single-stage single-speed centrifugal type supercharger – Fuel system: Fuel injection – Oil system: Dry sump with one pressure and two scavenge pumps – Cooling system: Liquid-cooled Performance: Power output: – 865 kW (1,175 PS - 1,160 hp) at 2,500 rpm for takeoff – 735 kW (1,000 PS - 985 hp) at 2,400 rpm for maximum continuous power Specific power: 25.5 kW/L (0.56 hp/in³) Compression ratio: 6.9:1 Specific fuel consumption: 0.27 kg/(kW·h) (0.45 lb/(hp·h)) Power-to-weight ratio: 1.44 kW/kg (0.88 hp/lb) Comments: The Daimler-Benz DB 601 was a German aircraft engine built during World War II. It was a liquid-cooled inverted V12, and powered the Messerschmitt Bf 109, among others. The DB 601 was basically an improved DB 600 with direct fuel injection. The DB 601Aa was licence-built in Japan by Aichi as the Atsuta and Kawasaki as Ha-60 to be used in the Ki-61 Hien and in Italy by Alfa-Romeo as R.A.1000 R.C.41-I Monsone for use in the C.202 Folgore. |
