About Fuel Injection Pump

The fuel injection pump is vital because it is the heart of the diesel engine. The device delivers fuel while maintaining a timing that keeps the engine running as smoothly as possible.

Fuel injection pump function

The fuel injection pump transmits fuel while maintaining a rhythm to keep the engine running properly, but it also regulates the amount of fuel necessary to achieve the desired power. The injection pump is a device that does the task of both the throttle and the ignition system necessary in gasoline engines. Better fuel injections result in better development of diesel engines.

Distributor injection pumps

This kind of pump only has a single fuel-metering plunger. A rotating rotor makes a hydraulic connection with different ports on the distributor. The rotary-style pump offers the benefit of having only one plunger and all the shots of fuel are the same. The distributor injection pump also has fewer moving parts compared to other devices.

Common issues with a malfunctioning fuel injection pump

A malfunctioning fuel injection pump can be caused by dirty fuel due to residue build-up, too little fuel, and timing disorder.
