Installation

With a full list of configurable options and an engine-mounted aftertreatment, the Cat C9.3B is an easy-to-install option that offers the power of larger engine platforms in a smaller engine package.

Advanced Features

Inlet throttle valve technology manages heat and in-cylinder dosing to create seamless DPF regeneration and a high-pressure common rail fuel system elimates the need for coolers, creating a simpler and lighter engine that's 18% more powerful than its predecessor engine—so operators get work done no matter when, no matter what.

Ideal Applications

Industrial, agricultural and construction applications such as: Pumps • Compressors • Chippers • Grinders • Asphalt paving equipment • Hydraulic power units • Bore rigs • Drill rigs • Tractors

Total Cost of Ownership

Between 500-hour oil service and 5000-hour DPF ash intervals and Caterpillar-patented design technology that enables the removal of EGRs, the need for parts and service keeps lifetime engine ownership costs down and ROI up. And because the Cat C9.3B uses the latest injector technology, owners can benefit from an overall fuel consumption reduction of up to 8% when compared to its predecessor engine.

Cat Dealer Product Support

Expert assistance is never far with the Cat C9.3B. With a five-year warranty and product support through the expansive global Cat Dealer Network, worldwide service and maintenance is all part of the package.

Safety

The Cat C9.3B is a finely tuned machine, running quieter and more efficiently than previous engines making it safer for job site operators who can stay focused on the task at hand.
