関用点火装置。[Claims for Utility Model Registration] An exciter coil provided in a four-pole magnet generator that induces two cycles of alternating current voltage per revolution of an internal combustion engine, an ignition coil, and an exciter coil provided on the primary side of the ignition coil. an ignition energy storage capacitor that is charged to one polarity by the output of the positive half cycle of the exciter coil; and a capacitor configured to discharge the charge of the capacitor through the primary coil of the ignition coil when triggered. An ignition device for an internal combustion engine comprising a discharge control thyristor and a thyristor trigger circuit that provides a trigger signal to the discharge control thyristor using the output of the negative half cycle of the exciter coil, the ignition device comprising: a signal coil that generates a signal, and an exciter coil short-circuiting switch that is triggered by the output of the signal coil and is provided to short-circuit the output of the negative half cycle of the exciter coil, wherein the signal coil is The position at which the exciter coil short-circuit switch is triggered is determined by the angle at which the output of the negative half cycle generated by the exciter coil rises at a timing different from the ignition timing of the internal engine, and the output of the negative half cycle of the exciter coil. An ignition device for an internal combustion engine, characterized in that the ignition device is set between an angle that reaches a trigger level of the discharge control thyristor.
