Fuel Injector

Fuel injectors are precision components within a vehicle's fuel delivery system, responsible for atomizing fuel and injecting it into the engine's combustion chambers. Located in the intake manifold or directly within the cylinder head, these electronically controlled valves deliver a precise fuel quantity for optimal engine performance, efficiency, and emissions control. Fuel injectors utilize a solenoid or piezoelectric actuator to open and close, responding to signals from the engine control unit (ECU). Common issues include clogging, leaks, and electrical failures, necessitating replacement to restore proper engine function. Examples in this category include fuel injectors for MAN trucks, such as MPN 51101006126 and 51.10100-6127, as well as those for BMW and Volvo commercial vehicles like MPN 22102390. These parts fall under the Engine Parts > Fuel Supply category.
