Mitsubishi 2G2 359cc engine Technical details and specifications

Make

Mitsubishi Motors Corporation

manufacturing period

1972 to 1976

type

In-line 2-cylinder SOHC

Displacement

0.36L

Cooling

Water

 

The Mitsubishi 2G2 series engine is a series of water- cooled in -line 2-cylinder gasoline engines for the company's light vehicles manufactured by Mitsubishi Motors and Mazda Porter Cab (550cc model) . It is a 4-stroke version of the company's 2G1 series engine for mini vehicles .

History

Commonly known as " Vulcan Engine" . The valve drive system uses SOHC , and the number of valves is 2 valves per cylinder with 1 intake and 1 exhaust. Except for the early model of 2G21 (Mujirushi Vulcan), all are equipped with a silent shaft . Initially, a timing chain was used to drive the camshaft, but a timing belt was used in the later model G23B, which will be described later . At the end of the series, the class's first turbo specification and the class's first air-cooled intercooler turbo specification were also added.

The successor is the 3G8 series , which was produced from 1987 to 2013 .

Variations

2G21 (Mujirushi Vulcan)

The first engine to appear, without a silent shaft. The MCA (Mitsubishi Clean Air) system is adopted to clear exhaust gas regulations . There was also a sports series engine equipped with a twin carburetor, which was installed in the Minica GS / GSL and Minica Skipper IV in place of the previous 2G10 engine.
