Functionality fuel injector

Fuel injectors play a central role in internal combustion engines, serving to deliver fuel with precision. They are part of the fuel injection system and control the timing, quantity and pressure of the injected fuel.

Precise control of these factors is critical to the engine's efficiency, performance, fuel economy and emission levels. The valves are electronically controlled and open to inject fuel when they receive a signal from the engine control unit. Fuel injector technology has advanced significantly over the years.
