Meets U.S. EPA Tier 4 Interim, EU Stage IIIB emission standards.
World-class manufacturing capability and processes coupled with proven core engine designs assure reliability, quiet operation, and many hours of productive life.
Series turbocharging with smart wastegate available on specific ratings for fast response, high power, and increased torque.
Fuel consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.
Tier 4 Interim or Tier 4 Final, Stage IIIB or 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, material handling, construction, mining, aircraft ground support, and other industrial applications.
Ideal for equipment with narrow engine compartments. Multiple installation options minimize total package size.
Worldwide service delivers ease of maintenance and simplifies the servicing routine. Hydraulic tappets, multi-vee belts, "no ash service" aftertreatment, and 500-hour oil change intervals enable low-cost maintenance. Many service items have a choice of location on either side of the engine to enable choice of service access. The S·O·SSM program is available from your Cat dealer to determine oil change intervals and provide optimal performance.
Every Cat engine is manufactured to stringent quality standards in order to assure customer satisfaction.
