Fuel Injection Pump (Part Number: 3281781PX)
A fuel injection pump is an essential component of a diesel engine that delivers fuel to the cylinders at the correct time and pressure. The Fuel Injection Pump (part number 3281781PX) is a high-quality pump designed specifically for use in diesel engines. It consists of a rotor, cam, distributor plunger, delivery valve, and timing advance mechanism. The rotor rotates inside the pump body, creating pressure in the fuel lines and delivering precise amounts of fuel to each cylinder at exactly the right time. The cam controls the timing of each injection event by moving the distributor plunger up and down. The delivery valve regulates fuel flow into each cylinder while also preventing backflow into the pump. Finally, the timing advance mechanism ensures that injection occurs at precisely timed intervals for optimal engine performance.
