充放電式点火装置。In the ignition device, the output of the exciter coil is stored in a charging/discharging capacitor, and the ignition thyristor is made conductive by the output of the signal coil, thereby discharging the electric charge of the charging/discharging capacitor and igniting the ignition device. A switching transistor that short-circuits the output of the signal coil is connected to the output end of the coil, and when the engine speed increases and the output of the signal coil increases, this switching transistor becomes conductive and prevents the ignition thyristor from being conductive. The capacitor charge/discharge type ignition device is characterized in that the switching transistor is switched to non-conductivity by the output of the auxiliary signal coil, whereby the ignition sirisk becomes conductive after a predetermined time delay.
