If you want to squeeze more power out of a 24-valve diesel Cummins engine, you might want to change out its fuel-injection pump with the P-pump conversion kit.

Diesel engines operate at higher compression ratios than gasoline engines, and fuel is injected under much higher pressure. An injection pump, usually driven by a belt or chain linked to the ...

The fuel injection pump is the heart of the diesel engine. Precisely delivered fuel maintains a rhythm or timing that keeps the engine running smooth. Simultaneously, the pump also controls the amount ...

Columbus told us that the Sigmas use oversized injector lines and 16mm plungers instead of the 12mm versions you'd normally find in a Bosch P7100. As engine rpm increases, the window of time you must ...

The clearances inside diesel injection system parts are closer than those found in any other technology. The plungers and needle valves in injectors need to fit tightly to ensure precise metering and ...

High-pressure common rail fuel (HPCR) systems are standard on nearly every diesel engine today, from heavy equipment to over-the-road trucks, light-duty trucks, large generators and more. HPCR fuel ...

Have you ever wondered how fuel gets from the tank of a car to its engine? Well, for a diesel engine, it all starts with the lift pump, which is a low-pressure pump that draws the fuel up and out of ...
