The Mitsubishi Kinsei (金星, Venus^?) was a 14-cylinder, air-cooled, twin-row radial aircraft engine developed by Mitsubishi Heavy Industries in Japan in 1934 for the Imperial Japanese Navy. The Mitsubishi model designation for this engine was A8 while it was an experimental project, in service it was known as the MK8 "Kinsei" by the Navy. In the middle of the war the engine was adopted by Army so it got designation Ha-112^[1]Unified designation code was Ha-33. Its basic design was based on the Pratt and Whitney R-1689 Hornet, but underwent numerous modifications and improvements.^[2]
