Fuel injection valve, location | at cylinder head | ||
Fuel injection valve, task | Spray the fuel onto the injectors as a finely atomized spray | ||
Fuel injection valve, design/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. The fuel injection valves are actuated by correspondingly long ground pulses from the engine control unit, Power supply from terminal 87. |
