2G2 Manufacturer Mitsubishi Motors Also called Vulcan Production 1972–1989 Predecessor Mitsubishi 2G1 engine Successor Mitsubishi 3G8 engine 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 It was an overhead camshaft design, and superseded the older two-stroke 2G1 series.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.

Specifications
Engine type Twin cylinder OHC Displacement 359 cc Bore x stroke 62.0 x 59.6 mm Fuel type Regular gasoline Peak power 22 kW (30 PS) at 6,000 rpm (Minica F4, Minicab 4) "Vulcan S", December 1974 on, with "Silent Shaft" balance shafts. (MCA-II)
24 kW (32 PS) at 8,000 rpm (Minica F4) First version, without balance shafts. (MCA)
26 kW (36 PS) at 8,500 rpm (Minica F4 GS, GSL, Minica Skipper IV) "Sports Series" with twin carbs. The F4 sports series was discontinued in October 1973.
Peak torque ?? N·m (?? ft·lbf) at ??00 rpm (MCA-II) 3.0 kg·m (29.4 N·m) at 5,500 rpm (MCA) 3.2 kg·m (31.4 N·m) at 6,500 rpm (twin-carb sports) "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.
