Diesel Pump CT

Generating High Injection Pressure

The primary function of the Diesel Pump CT is to draw fuel from the tank and pressurize it to the extremely high levels required for direct injection into the combustion chamber. This high pressure is fundamental for the atomization process and is critical for the powerful, efficient operation of heavy-duty Caterpillar engines in excavators and other machinery.

Precise Fuel Metering and Delivery

The pump precisely controls the volume of fuel delivered to each injector based on engine load and speed demands. This ensures the correct air-fuel ratio for combustion, allowing the engine to generate the required power efficiently while preventing issues like black smoke from over-fueling or power loss from under-fueling.

Timed Fuel Distribution

Working in sync with the engine's timing system, the pump ensures that pressurized fuel is available at the injectors at the exact moment required in the piston's cycle. This precise timing is crucial for maximizing power output, fuel efficiency, and ensuring smooth engine operation under varying loads.
