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.
