ンデンサ充放電式点火装置。In the ignition device, the output of the exciter coil is stored in the 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 delay circuit and a control thyristor are connected in parallel between the signal coil and the gate of the ignition thyristor, and when the engine speed is low, the control thyristor triggers the ignition thyristor. When ignition is performed and the engine speed is high, the control thyristor is cut off by the output of the exciter coil, and the ignition thyristor is delayed and triggered by the delay circuit. A capacitor charge/discharge type ignition device.
