Basic Concepts of Fuel Injection Pumps

A fuel injection pump delivers fuel to the engine’s combustion chambers. In diesel engines, it pressurizes and injects fuel at the correct time and quantity, providing more precise control over fuel delivery compared to carburetors, which is essential for the efficient operation of diesel engines ⁴.

Operation of the Cummins 4932736 Fuel Injection Pump

This Cummins part operates through mechanical and hydraulic processes. It consists of a cam, plungers, and a delivery valve. As the engine runs, the cam rotates, actuating the plungers to draw fuel into the pump and then pressurize it. The pressurized fuel is delivered to the injectors, which spray it into the combustion chambers at the precise moment for optimal combustion ¹.
