Description
The fuel injector is a small, precise solenoid valve. When the ECM supplies a ground to the fuel injector circuit, the coil in the fuel injector is energized. The energized coil pulls the ball valve back and allows fuel to flow via the fuel injector into the intake manifold. The amount of fuel injected depends upon the injection pulse duration.
Pulse duration is the length of time the fuel injector remains open.
The ECM controls the injection pulse duration based on engine fuel needs.
