Benefits and Features

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 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.

  • Scheduled maintenance, including SOSSM sample
  • Customer Support Agreements (CSA)
  • Caterpillar Extended Service Coverage (ESC)
  • Superior dealer service network
  • Extended dealer service network through the Cat Industrial Service Distributor (ISD) program


Regeneration. Cat Regeneration System maximizes fuel efficiency during regeneration. Transparent regeneration maximizes uptime. Aftertreatment life is twice as long as engine rebuild

Mounting. Industrial power units have standard horizontal mounting.
Service. Minimum 5000-hour diesel particulate filter ash service interval. PETU filter service is 5000 hours.
