The Klimov M-105 was a V12 liquid-cooled piston aircraft engine used by Soviet aircraft during World War II.[1]

Development

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 the first Klimov V-12 engine design to place the induction system 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 the lead designer's initials.
