Abstract (en)

[origin: WO0052326A1] The invention relates to a system and a method for controlling a control valve for a diesel fuel injection system, comprising a fuel injector with a pressure amplifier. The control valve (10) is positioned upstream of the pressure amplifier. The valve spool (20) of the control valve (10) is moved back and forth by two physically separate magnetic coils (30, 32). When one of said two magnetic coils (30; 32) is electrically controlled by a control current the other magnetic coil (32; 30) is switched to a sensor function so that the current induced in the sensor by a movement of the valve spool (20) is detected.
