Meets U.S. EPA Tier 4 Final emission standards. Designed to meet proposed EU Stage V emission standards. As of publishing date, Stage V regulations have not been finalized.
World-class manufacturing capability and processes coupled with proven core engine designs assure reliability, quiet operation, and many hours of productive life.
High power density. With peak power increased by over 18%, you can look to downsize the displacement of the engine currently powering your application. Simple and efficient turbocharger provides optimal air management and improved fuel efficiency.
Fluid consumption optimized to match operating cycles of a wide range of equipment and applications while maintaining low operating costs.
Exceptional power density enables you to use a smaller displacement engine than previously, and optimize the installation in your application. Multiple installation options minimize total package size. Ideal for equipment with narrow engine compartments. Additional aftertreatment flexibility to package in your machine including ability to mount cans separately and vertical mounting option. Compact aftertreatment option to limit requirements on packaging space. Low heat rejection levels, similar to previous emission standards, allow for reduced cooling package size and cost.
Worldwide service delivers ease of maintenance and simplifies the servicing routine. If applicable, minimum 5000-hour diesel particulate filter (DPF) ash service interval enables low-cost maintenance. Capable of optimal oil change intervals of up to 500-hours, depending on rating, application, operating conditions, and maintenance practices. Engine B10 life up to 10000 hours for Tier 4 Final, Stage IV. 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 standards in order to assure customer satisfaction.
Regeneration. Cat Regeneration System maximizes fuel efficiency during regeneration. Transparent regeneration maximizes uptime. Aftertreatment life is twice as long as engine rebuild
The C9.3B is equipped for the future. High speed communication between the engine ECM and telematics hardware enables advanced engine monitoring, onboard analytics, remote services, including software updates, and more.
