	Fuel injector, location	At cylinder head
	Fuel injector, task	Spraying the fuel onto the injectors in the form a finely atomized spray
	Fuel injection valve structure/function	When energizing the magnet coil (3) the nozzle needle (5) is lifted above the solenoid armature (4) against the coil spring (11) by approx. 0.1 mm and the fuel flows out of the holes. Actuation of the fuel injection valves occurs over correspondingly long earth impulses from the engine control unit, power supply from terminal 87.
