The Klimov VK-107 was a V-12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II .
5-521: The VK-107 was developed from the M-105 and VK-106 . To achieve a greater power output, each cylinder now had four valves (two intake and two exhaust), crankshaft and camshafts were completely revised, and a new supercharger design was implemented. Although the engine could have been ready for production as early as 1942, the Soviets ' factories lacked the capacity to produce a brand new design. Thus,
10-428: The first Klimov V-12 engine design to use reverse-flow cylinder heads , forcing the induction system to be placed on the outside of the cylinder banks, with the exhaust system also exiting from the outboard side, with twin sets of "siamesed" exhaust ports adjacent to each other. About 129,000 M-105 and its variants were built. During the war, Klimov's engines were redesignated from "M" (for "motor," engine) to "VK" for
15-443: The less powerful Klimov VK-105PF and VK-105PF2 V12 engines were built instead. However, the appearance of Luftwaffe Messerschmitt Bf 109G with Daimler-Benz DB 605 engine in 1943 created an urgent demand for a more powerful engine. VK-107A was put into production in 1944 and was used on Yak-9U fighters. The engine was not well liked by either pilots or mechanics – it had a life expectancy of only 25 hours and war emergency power
20-568: Was a V12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II . The M-105, designed in 1940, drew heavily on Klimov's experience with the Hispano-Suiza 12Y ( license-built as the M-100). In addition to a two-speed supercharger , the M-105 had several improvements like two intake valves per cylinder and a counterbalanced crankshaft . The M-105 was
25-540: Was almost never used for fear of decreasing this even more. The engine was also difficult to service, in part because its exhaust headers were on the inside of the cylinder banks, the reverse placement of most V-type liquid-cooled engine designs.
