Mitsubishi 2G1 engine

The Mitsubishi 2G1 is a water-cooled, iron-block, two-stroke twin-cylinder engine built by Mitsubishi Motors for the kei car class from 1968. It was introduced in the first generation Minica to replace and complement the otherwise similar air-cooled ME24. Its name follows Mitsubishi's 1967 change in engine naming, with 2G1 meaning the first family of two-cylinder gasoline engines; the 2G10 was the first displacement version and later sub-iterations carry numbers after a dash. A four-stroke engine of identical displacement, the 2G21 Vulcan, appeared in September 1972, but the two-stroke continued as a low-cost alternative, mainly for commercial vehicles, until new kei regulations took effect in January 1976. It powered the Minica and the Minicab W.
