Diesel and Natural Gas Engines

Engine Cat diesel and natural gas engines and engine systems provide power to the world via 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.

Cat diesel engines deliver legendary economy and durability while meeting today’s stringent emission requirements. Our innovative technology meets today's industry clean air regulations and establishes the building blocks for attaining the requirements of tomorrow without the fuel and maintenance penalties associated with EGR engines.  

Cat natural gas and diesel power engines offer another major advantage - they’re supported by Empire's legendary product support network and a team of skilled, certified technicians ready to keep you up and running.

Diesel Power Generators

Cat diesel generators from Empire offer a number of important advantages for your facility. Diesel generators can significantly reduce your overall fuel consumption, which can lower your operating costs by as much as 50 percent when compared to other fuel sources. Diesel generators also run cooler, making them easier and less expensive to maintain while providing a longer lifespan.

Diesel power generators from Empire can be a highly reliable power generation source for use as either a primary or backup power supply. Cat engine-powered diesel generators are available with a ratings range from 13kW to 17,460 kW and offer a large number of factory options.

Natural Gas Power Generation

Cat natural gas generator sets powered by Cat engines are designed to provide maximum fuel efficiency along with the low life-cycle costs that can give a welcome boost to your company’s bottom line. Cat natural gas generators are easy to install and feature a wide assortment of factory options that enable you to customize your generator to meet your specific power needs.

You’ll also get the benefit of emissions compliance with most environmental regulatory agencies, as well as Empire’s single-source and turnkey support. Natural gas power generation offers a ratings range from 65 to 6520 kW.

Natural Gas Engines

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.
