Claims

[Scope of utility model registration request]

an ignition coil, an exciter coil arranged in a four-pole magnet generator that is driven in synchronization with the rotation of the internal combustion engine that drives the vehicle and which induces an alternating current voltage of two cycles per rotation; and a primary of the ignition coil. an ignition energy storage capacitor provided on the side and charged to one polarity by the output of the first polarity half cycle of the exciter coil; and an ignition energy storage capacitor that is charged to one polarity by the output of the first polarity half cycle of the exciter coil; a discharge control thyristor provided to cause discharge; a signal supply circuit that provides an ignition signal to the thyristor with the output of a second polarity half cycle of the exciter coil; and a first polarity half cycle of the exciter coil. an exciter shorting circuit that shorts the exciter coil when the output of the cycle reaches a predetermined level; and an exciter shorting circuit that discharges the integrating capacitor when the output of the second polarity half cycle of the exciter coil rises. an integrating circuit that starts charging the integrating capacitor when the integrating capacitor becomes conductive and charges the integrating capacitor with a constant time constant; a comparing circuit that compares the terminal voltage of the integrating capacitor with a reference voltage; and an output of the comparing circuit. control, and when the terminal voltage of the integrating capacitor is below a reference voltage at the rising edge of the first polarity half cycle of the exciter coil, charging of the ignition energy storage capacitor is inhibited to prevent ignition operation. In the ignition device for an internal combustion engine, the magnet generator is configured to make one half-cycle output of the first polarity, which is generated in the exciter coil twice per revolution of the engine, smaller than the other.
