Meets U.S. EPA Tier 4 Final, 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.
Leading-edge technology provides significant improvements in power, torque, fuel consumption and response. Technology includes single smart wastegated turbo systems, durable high pressure common rail technology, and closed circuit breathing system.
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.
Worldwide service delivers ease of maintenance and simplifies the servicing routine. Capable of optimal oil change intervals of 500 hours. Service-free through-flow diesel particulate filter (DPF) for Tier 4 Final, Stage IIIB. The S·O·S℠ 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.
