Benefits and Features

Designed to meet U.S. EPA Tier 4 Final and EU Stage IV emission standards.

World-class manufacturing capability and processes coupled with proven core engine designs assure reliability, quiet operation, and many hours of productive life.

Simple and efficient turbocharger with balance valve provides optimal air management and improved fuel efficiency.

Fuel consumption optimized to match operating cycles of a wide range of equipment and applications.

Tier 4 Final, Stage IV engines require Ultra Low Sulfur Diesel (ULSD) fuel containing a maximum of 15 ppm sulfur, and new oil formulations to support the new technology. Cat® engines are designed to accommodate B20 biofuel. Your Cat dealer can provide more information regarding fuel and oil.

Industry-leading range of factory configurable ratings and options for agricultural, materials-handling, construction, mining, forestry, waste, and other industrial applications.

Exceptional power density enables standardization across numerous applications. Multiple installation options available to minimize total package size.

Worldwide service delivers ease of maintenance and simplifies the servicing routine. Minimum 5000-hour diesel particulate filter (DPF) ash service interval enables low-cost maintenance. Capable of optimal oil change intervals of up to 500 hours, depending on rating, application, operating conditions, and maintenance practices. Engine is designed for a B10 life of up to 10,000 hours. The S•O•SSMprogram is available from your Cat dealer to determine oil change intervals and provide optimal performance.

Every Cat engine is manufactured to stringent standards in order to assure customer satisfaction.
