The Mitsubishi Kasei ( 火星 , Mars ) was a two-row, xiv-cylinder air-cooled radial engine congenital by Mitsubishi Heavy Industries and used in a variety of World War Two Japanese shipping, such equally Mitsubishi J2M and Mitsubishi G4M.^[1] The Mitsubishi model designation for this engine was A10 while information technology was an experimental project, in service it was known as the MK4, and known equally the Ha101 & Ha111 by the Army and Kasei by the Navy. Co-ordinate to unified designation code it was Ha-32 of the variants from 11 to 27.

Design and development [edit]

Although originally ordered by the Imperial Japanese Navy, the Kasei was based on the earlier Mitsubishi Shinten engine, itself based originally on the Mitsubishi Kinsei. Produced in a wide variety of models, the Kasei began with a rated ability of i,530 horsepower (i,140 kW), with a gradual evolution to 1,850 horsepower (1,380 kW) in afterward wartime versions. Three variants were adult for the Japanese Navy starting in 1939. It was also later adopted past the Imperial Japanese Army as the Ha-101 engine. Unified code was Ha-32.

Physically, the engine had a rather large 1,322 millimetres (52.0 in) diameter compared to the one,180 millimetres (46.five in) of the Nakajima Homare engine. Its size and weight meant it was a challenging engine to use on unmarried engine fighters.^{[ citation needed ]}
