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 1941 the engine was adopted by Army, receiving designation Ha-112[1] (later Ha-112-I, 1,300hp Army Type 1). In May 1943 it received Ha-33 unified designation code.[2]
