Fuel Injector: Description and Operation
Fuel Injector - Cutaway View
Fuel Injection Control consists of the MPI System sensors and switches and the injectors. The injectors are solenoid operated valves, installed in the
intake manifold. When the solenoid coil is energized, the plunger is attracted. The needle valve that is attached to the plunger is pulled to the full open
position and fuel is injected through the valve. When the solenoid is de-energized spring pressure closes the valve. Since the injection nozzle opening is
a fixed size and the fuel pressure is also fixed, the injection amount is determined by the duration which the needle valve is open.
