Mitsubishi engine types

By the names of engines of the MITSUBISHI much can not be said, as well as the names of engines of other companies (of course, except for TOYOTA and NISSAN).

The first figure in the name of the engine MITSUBISHI speaks about the number of cylinders. Examples: 4D56; 6G72; 3G83; 8A80.

The following letter gives some information about the type of engine:

• A or G – gasoline engines (what is the difference between them is not clear yet). Examples: 4G15, 8A80, 6G72.
• D – diesel with a mechanically controlled high-pressure fuel pump (injection pump). Examples: 4D56; 4D55.
• M – diesel with electronically controlled fuel pump. Examples: 4M40; 4M41.

The last two digits indicate that the engine belongs to a series of engines. Motors having the same name (and correspondingly belonging to the same series) have a similar design, but they may differ in the degree of forcing, the working volume, the way of filling the working mixture. However, for engines 4G13 and 4G15 there is a correspondence of the name to the working volume: the first one has 1.3 liters, while the second one has 1.5 liters.

The old MITSUBISHI engines (development before 1989) might not have the first digit in the name showing the number of cylinders, but they had a letter at the end (which means it is not known), and the names became similar to SUZUKI engine names. Example: G13B (carburetor, 4-cylinder engine with 3 valves per cylinder).
