Claims

[Scope of utility model registration request]

A capacitor is charged by an alternating current voltage output from a charging coil of an alternator driven by the rotation of the engine, and a switching element is activated based on an ignition signal output from a signal coil of the generator in synchronization with the rotation of the engine. In a capacitive discharge ignition device that controls and discharges the capacitor to generate a high voltage in the ignition coil and apply it to the ignition plug, the phase of the ignition signal and the alternating current voltage are used to charge the capacitor when the engine rotates in the forward direction. The phases of the voltages that do not match are matched, and the charging coil and the speed
a reverse rotation prevention control circuit connected to the switching element and activated by the AC voltage used to charge the capacitor when the engine rotates in reverse to disable the switching element; Discharge ignition device.
