No matter what kind of equipment you build, there's a Cat diesel engine to fit your needs. Cat diesel engines cover the widest power range in the industry, from 10 to 6598 bhp (8 to 4920 bkW). Our 3600 Family of large-bore diesel engines offer heavy fuel capability. Learn about Cat diesel engine families here. Then follow the links to view or download specifications on models of interest.

Cat gas engines fit a wide range of industrial applications. Gas engines carry ratings from 55-4705 bhp (41-3509 bkW).

As concern for air quality grows, so does the role of gas engines. Caterpillar developed its first gas engines more than 50 years ago and continues to lead with innovations that deliver high performance and fuel economy as well as clean emissions. Gas engines let you choose the most available or affordable gaseous fuel: natural gas, field gas, propane, landfill gas and digester gas all can be burned cleanly and efficiently.

Gas engines include the Cat Electronic Ignition System, which uses state-of-the-art microprocessor technology to control key parameters such as timing and detonation protection. The EIS also has built-in diagnostics covering nearly every facet of the ignition system.

All Cat gas engines are based on rugged diesel engine frames. That means high reliability, low maintenance and repair costs, and long service life. Components such as blocks, crankshafts, heads, liners and connecting rods are also the same as those used in Cat diesel engines.
