Abstract

PURPOSE:To permit the operation level to be varied in high or low speed range by connecting a diode, a condenser, and a reverse constant voltage diode in series and a resistance in parallel between an ignition circuit and a contactless ignition apparatus using a pulser. CONSTITUTION:As the output of a pulser coil 2 is below the breakdown voltage VZ of a diode 13 in a low revolution range, a condenser 7 is not charged, and the operation level of an ignition circuit 3 is made constant with a resistance 8, and ignition starts at the most rear edge of a projection when the voltage of the pulser coil at the second step 100 is low. In the idle revolution range, the voltage VPE at the step 100 becomes higher than the operation level, and the ignition position advances to the position corresponding to the step 100. When the voltage VPE exceeds the voltage VZ in high revolution range, charging is performed during the breakdown period, then discharging is performed through the resistance 8, up to the next signal. Thus, VPE is transmitted to an ignition circuit 3 trough the resistance 8 by setting VZ in such a way that the voltage VDP of the condenser 7 may drop below VPE at the next time point of the step 100 signal.
