The Mitsubishi Vulcan engine, identified by the code 2G2, is an iron-block twin cylinder engine with three main bearings, built by Mitsubishi Motors for kei car class vehicles from September 1972. It was an overhead camshaft design, and superseded the older two-stroke 2G1 series. The 2G2 was in turn replaced by the Multi-valve 3G8 three-cylinder series.
"Vulcan S", December 1974 on, with "Silent Shaft" balance shafts. (MCA-II)
First version, without balance shafts. (MCA)
"Sports Series" with twin carbs. The F4 sports series was discontinued in October 1973.
"MCA" stood for "Mitsubishi Clean Air", reflecting Japan's new air quality laws. The MCA-II was cleaner yet, and with balance shafts it also offered a much smoother run, at the loss of a few horsepower. The Sports engine did not meet the stricter emissions laws, which led to the demise of the Skipper.

This engine met the enlarged kei-jidosha regulations which took effect in 1975. It was called the Vulcan S in period advertising. It had been thought that the rules would only allow for 500 cc, so a number of manufacturers had to quickly develop 550 cc models. The 2G22 was only built for ten months.
The G23B engines also featured the MCA-JET improved emissions system with a catalytic converter and three valves per cylinder. For the last two years (until summer of 1989), production was only for the Mazda Porter.
