Claims

[Scope of utility model registration request]

While rectifying the output of the charging coil of the alternator to charge the capacitor, an ignition signal is applied to the control terminal of the semiconductor switching element via a time constant circuit consisting of a resistive element and a capacitor, and the charge in the capacitor is In a capacitive discharge ignition device that discharges to the primary coil of the ignition coil and induces a high voltage in the secondary coil, a plurality of magnets with different polarities are arranged alternately along the circumferential direction on the inner peripheral surface of the rotor. A power generating coil that generates the ignition timing signal is disposed together with the charging coil inside the rotor of the alternator installed in the AC generator and facing each of the magnets as the rotor rotates. Capacitive liquid electric igniter.
