The Mitsubishi 2G10 is a water- cooled 2-stroke in-line 2-cylinder gasoline engine for the company's mini vehicles manufactured by Mitsubishi Motors (originally Mitsubishi Heavy Industries ) .

It is a liquid-cooled engine with a cast -iron cylinder block and crankcase , developed to replace the air-cooled ME24 engine . It was first installed in the company's first Minica (late model, LA23) in 1968 , and later installed in the company's Minica Skipper and the second generation Minicab truck (late model). , Furthermore, it continued to be produced for a long time after the change to yellow number.

The reason why the name changed from the ME24 type is that in 1967  the engine naming convention in Mitsubishi cars was changed . 2G1 indicates the first series of two -cylinder petrol engines , and 2G10 0 indicates that it was the first engine developed in the series . In addition, the 2G10 type indicated that there were various variations by adding a hyphen and a number after the model name (2G10 -5 as an example).

The 2G10 type did not officially have name , but the air cleaner box was painted in a different color depending on the model it was installed on, and it was nicknamed the red engine or gold engine  .

The successor is the 2G2 series , a 4-stroke version of the 2G10 type that appeared in September 1972. The shift to 4-stroke was in anticipation of tightening automobile exhaust gas regulations , and was positioned as the decisive blow for the Mitsubishi Clean Air System (MCA) for mini vehicles. However, the 2G10 continued to be manufactured as a low-end engine until the standard for light vehicles was expanded to 550 cc in January 1976 .
