Overview
The Cat C9.3B combines a new high pressure common rail fuel system and advanced aftertreatment technology to produce 340 kW of power. With exceptional power density, the C9.3B allows for platform downsizing while maintaining reliability and durability. Our focus is locked on maximizing performance with simpler engine systems and reduced installation complexity through modular, flexible designs.
Specifications
| Maximum Power | 456 HP |
| Maximum Torque | 1540 lb-ft @ 1400 rpm |
| Rated Speed | 1800-2200 rpm |
| Maximum Power | 340 kW |
| Maximum Torque | 2088 Nm @ 1400 rpm |
| Rated Speed | 1800-2200 rpm |
Benefits & Features
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.
