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 Final, or Stage V 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.
Exceptional power density enables standardization across numerous applications. Multiple installation options minimize total package size. Ideal for equipment with narrow engine compartments.
Worldwide service delivers ease of maintenance and simplifies the servicing routine. Hydraulic tappets, multi-vee belts, minimum 5000-hour diesel particulate filter (DPF) ash service interval 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 standards in order to assure customer satisfaction.
Regeneration. The DOC/SCR modular design offers a simple, compact package while providing high levels of performance. A DOC/DPF/SCR option is available for higher power machines. While in use, both DOC/SCR an DOC/DPF/SCR systems offer transparent operation to the user.
