Reliable, Quiet and Durable Power
World-class manufacturing capability and processes coupled with proven core engine designs assure reliability, quiet operation, and many hours of productive life.
High Performance
Simple and efficient turbocharger with balance valve provides optimal air management and improved fuel efficiency.
Fuel Efficiency
Fuel consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.
Fuel & Oil
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.
Broad Application Range
Industry leading range of factory configurable ratings and options for agricultural, material handling, construction, mining, aircraft ground support, and other industrial applications.
