ABSTRACT:
A fuel injection valve for injecting fuel into an internal combustion engine has a valve element lift sensor for producing an output signal in response to pressure developed by movement of a valve element. A detected valve element lifting signal produced from the valve element lift sensor is shaped into a waveform, and employed to generate a pulse having a pulse duration shorter than a minimum valve element lifting period and longer than the duration of a pulse issued from a waveform shaper after the supply of fuel to the fuel injection valve has been cut off. The generated pulse and the shaped valve element lifting signal are ANDed to remove noise from the output signal of the valve element lift sensor.
