Emissions

Designed to meet U.S. EPA Tier 4 Interim or U.S. EPA Tier 4 Final, EU Stage IIIB or EU Stage IV emission standards.

Reliable, Quiet and Durable Power

World-class manufacturing capability and processescoupled with proven core engine designs assurereliability, quiet operation, and many hours ofproductive life.

High Performance

Series turbocharging with smart wastegate available on specific ratings for fast response, high power, and increased torque.

Fuel Efficiency

Fuel consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.

Fuel & Oil

Los motores Tier 4 Interim o Tier 4 Final, Stage IIIB o Stage IV requieren combustible diesel ultra bajo en azufre (ULSD, Ultra Low Sulfur Diesel) que contenga un máximo de 15 ppm de azufre y nuevas formulaciones de aceite que respalden la nueva tecnología. Los motores Cat® están diseñados para adaptarse al biocombustible B20. Su distribuidor Cat puede entregarle más información sobre el combustible y el aceite.

Broad Application Range

Industry leading range of factory configurable ratingsand options for agricultural, material handling,construction, mining, aircraft ground support, and otherindustrial applications.

Package Size

Ideal for equipment with narrow engine compartments. Multiple installation options minimize total package size.

Low Cost Maintenance

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.

Quality

Every Cat engine is manufactured to stringent quality standards in order to assure customer satisfaction.
