The Mitsubishi 2G1 engine is a water-cooled iron-block two-stroke twin-cylinder engine built by Mitsubishi Motors for the kei car class from 1968. They were first introduced in the first generation Minica[1] to replace (and to complement) the otherwise similar but air-cooled ME24 powerplant.[2] The difference of nomenclature compared to the ME24 is due to Mitsubishi's 1967 change of engine naming practice, 2G1 meaning it was in the first family of two-cylinder gasoline-powered engines. The "0" in "2G10" means that it was the first displacement version produced, with numbers after a dash (e.g. 2G10-5) then denoting the various subiterations.
The 2G10 engine was replaced by the 2G21 "Vulcan" engine, a four-stroke unit of identical displacement which first appeared in September 1972. The two-stroke 2G10 did continue to be produced as a low-cost alternative until new Kei car regulations took effect in January 1976, mainly for commercial vehicles.
