This part’s efficiency and reliability are integral to the overall performance, fuel economy, and emissions control of the vehicle ¹.

Basic Concepts of Fuel Injection Pumps

A fuel injection pump is a device that pressurizes and delivers fuel to the engine’s injectors. In diesel engines, this pump operates by creating high-pressure fuel that is then injected into the combustion chamber at precise moments in the engine cycle. This process enhances combustion efficiency and power output. 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 computer controls to optimize fuel injection based on engine conditions and performance requirements ².
