Basic Concepts of Fuel Injection Pumps

A fuel injection pump is a device that delivers fuel to the engine’s combustion chambers at the correct timing and pressure. In diesel engines, this pump plays a role in the fuel delivery system by atomizing the fuel and injecting it into the cylinders at high pressure. This process facilitates efficient combustion. Fuel injection systems can be mechanical or electronic. Mechanical systems rely on physical components and cam-driven mechanisms to control fuel delivery, whereas electronic systems use sensors and electronic control units (ECUs) to manage fuel injection more precisely ¹.
