On the road or at sea, moving ground or deep beneath it, Caterpillar engines power the world. With more than 500 types, we’re among the world’s largest engine makers, and the only one with ACERT™ Technology.

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 10 - 21,760 hp (8 - 16,000 kw).

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.
