A portion of Caterpillar Inc. business is in the manufacturing of diesel and natural gas engines and gas turbines. These are used in the company's own on and offroad vehicles, peak-load power plants and emergency generators. They are also sold to other OEMs for use as the prime movers in locomotives, trucks and ships.

Caterpillar also owns Perkins diesels of the UK, a manufacture of diesel engines since 1932. Caterpillar acquired Perkins from Massey-Ferguson in 1998.

Caterpillar engines range from the 5.5hp C0.5 to the 6,900hp 3616.
