Engine and Power Systems
Caterpillar is the world's largest manufacturer of medium speed engines, as well as one of the world's largest manufacturers of high speed diesel engines, with ratings available from 54 to 13,600 hp (40 to 10,000 kW). Caterpillar is also a major supplier of HD diesel fuel systems, including the revolutionary HEUITM fuel system, and the world's largest producer of HD natural gas engines.

Caterpillar engines and engine systems provide power to the world. Our engines provide power to trucks, ships and boats, our own construction and mining machines, and much more. Electrical power systems supply both primary and standby power for a variety of uses - like off-shore oil rigs, huge mines in remote deserts or mountain ranges, entire communities in areas not close to a utility power grid, hospitals, schools, factories, airports and office buildings.
