Fuel Injector: Description and Operation

PURPOSE
The fuel injectors supply highly atomized fuel at the intake port to ensure optimum combustion efficiency.

OPERATION
The eight fuel injectors are fitted between the pressurized fuel rail and inlet manifold. Each injector comprises a solenoid operated needle valve with a movable plunger rigidly attached to the nozzle valve. When the solenoid is energized the plunger is lifted off its seat and allows pressurized fuel into the intake manifold.
