ABSTRACT:
An ionization current detector for detecting the combustion states of an internal combustion engine is disclosed, which comprises: a high voltage generation circuit means, including a series circuit of a resistor, a diode, a capacitor, and a Zener diode, coupled across the output terminal of the ignition coil and the ground; diodes coupled across the peripheral terminals of the distributor and a negative terminal of the capacitor; and a current detector circuit including a resistor coupled across the positive terminal of the capacitor and the ground and a voltage divider for detecting the amount of the ionization current. An additional Zener diode is coupled in parallel with the capacitor to limit the voltage across the capacitor. The whole detector is incorporated into a single unit mounted to the distributor cap.
