Installation
With numerous configurable options available and an engine-mounted aftertreatment system, the Cat C9.3B is easy to install and delivers power comparable to larger engine platforms, all within a compact design.
Advanced Features
The throttle valve technology manages heat and in-cylinder dosing to enable seamless DPF regeneration, while the high-pressure common rail fuel system eliminates the need for coolers, resulting in a simpler, lighter engine that is 18% more powerful than its predecessor. This ensures operators are never slowed down in their operations.
Ideal Applications
Applications in the industrial, agricultural, and construction sectors, such as: Pumps • Compressors • Chippers • Grinders • Asphalt paving equipment • Hydraulic power units • Drilling rigs • Trenchers • Tractors
Reduce Total Cost of Ownership
With 500-hour maintenance intervals for oil changes and 5,000-hour intervals for the diesel particulate filter, combined with Caterpillar's patented design technology that eliminates the need for exhaust gas recirculation (EGR), the reduced need for replacement parts and maintenance lowers engine ownership costs and increases return on investment. Additionally, the Cat C9.3B leverages the latest injector technology, enabling owners to achieve an overall fuel consumption reduction of up to 8% compared to its predecessor.
After-Sales Service
Easily access expert support for your Cat C9.3B. With the included warranty and after-sales service provided by the extensive global Cat dealer network, enjoy maintenance and service anywhere in the world. For more information, please contact your Cat dealer.
Safety
The Cat C9.3B is a sophisticated engine with quieter and more efficient operation than previous models, ensuring operator safety on the job site by allowing them to stay focused on their tasks.
