Auxiliary Engines

Scheduled maintenance or emergency shutdowns shouldn't mean your operation has to stop moving. Cat® auxiliary engines keep your equipment running efficiently during planned or unexpected downtime. From propulsion systems and backup generators to pumps and compressors, these engines provide the consistent power your business needs.

Thompson Power Systems offers Cat auxiliary engines that meet industry emissions standards, with capacities ranging from 71 to 5420 kilowatts. Our experts can help industrial facilities, marine vessels, and construction crews choose the most beneficial solutions for their power requirements.

Auxiliary Engine Parts and Functions

Caterpillar builds aux engines that perform reliably and efficiently in the most demanding operating conditions. The engine blocks contain heat-resistant alloys that maintain exceptional strength in extreme temperatures. Multistage cooling systems prevent overheating by regulating engine temperature in all operating conditions.

The fuel injection system uses turbochargers to deliver continuous power, while the advanced electronic control system monitors performance and adjusts settings to prevent engine strain.

Types of Auxiliary Engines We Offer

From data centers and hospitals to ships and offshore platforms, countless operations demand unique power solutions. We offer a complete lineup of engine models, including options like:

• Auxiliary engine generator sets: The C4.4 through C18 series delivers 71 to 803 brake kilowatts for onboard electrical systems and facility power. These engines keep power steady even when electrical demands change, protecting sensitive equipment and backing up critical systems.
• Marine auxiliary engines: The C9.3 to C280 series delivers 218 to 5,420 brake kilowatts for marine applications. Built with enhanced cooling and filtration systems, these engines handle harsh conditions while meeting strict emissions standards.
• Auxiliary diesel propulsion engines: The C32 series produces 314 to 1,333 brake kilowatts and works with electric drive systems to move vessels efficiently. These engines give you precise control while using less fuel during variable-speed operations.
