Added by BulldozerD11A portion of Caterpillar Inc. business is in the manufacturing of diesel and natural gas engines and gas turbines, which, in addition to their use in the company's own vehicles, are sold to other OEMs for use as the prime movers in locomotives, semi trucks, and ships, as well as providing the power source for peak-load power plants and emergency generators.
Caterpillar also owns Perkins diesels of the UK, a manufacture of diesel engines since the 1930s. They bought Perkins off Massey-Ferguson. Perkins owns the Rolls Royce engines and Cummins brands as well.
Caterpillar engines range from 30 hp (?) to 7,300 hp in size with some being 2 engines connected to together.
They have several factories of 1m sq ft just building engines. Most other manufactures buy them in but CAT from the early days of moving to Diesel power have built there own.
