とを特徴とするエンジンの無接点点火装置。A capacitor is charged with a positive direction voltage of a magnet generator driven in synchronization with the engine, and the charge of the capacitor is discharged to a primary coil of an ignition coil by making a thyristor conductive with a negative direction voltage of the magnet generator, In a non-contact ignition device for an engine that generates high voltage in the secondary coil to ignite the engine, the initial current of the negative voltage induced in the magnet generator is short-circuited between the gate and cathode of the thyristor. Non-contact ignition for an engine, characterized in that a thyristor conduction control circuit consisting of a main switching element that makes the main switching element conductive, an auxiliary switching element that makes the main switching element non-conductive, and a capacitor delay circuit that drives the auxiliary switching element are connected. Device.
