Abstract

PURPOSE: To eliminate noise due to vibration, etc. and increase detection accuracy by detecting through a smoothing means, output voltage from a piezoelectric element to be used as a fuel injection timing detector.
CONSTITUTION: Output voltage from a piezoelectric element which is assembled in the fuel injection valve not shown in the figure, and serving to detect the injection timing is received as signal Tin, any existent noise is absorbed and smoothed by capacitor C1 and resistor R1 which are connected in parallel. Then, it is inputted into an operational amplifier OP1 and amplified. Its output signal is inputted into an operational amplifier OP2 acting as a comparator, and transmitted therefrom as the reference voltage signal Tout.
