List of Mitsubishi engines

Mitsubishi Motors uses a simple four-digit naming scheme for its automobile engines:

* The first digit signifies the number of cylinders
* The second is the fuel type; "G" for gasoline
* The third is the engine family
* The fourth is the engine model

The first digit is sometimes omitted, shifting the entire scheme by one to make room for another character, such as "T" for turbocharged or "B" for second-generation.
