レベルを設定してなることを特徴とする内燃機関
の無接点点火装置。 A rotor having magnetic poles, a core disposed opposite to the rotor and having an exciter coil and a trigger coil wound thereon, and an ignition charge/discharge capacitor that charges the positive induced voltage of the exciter coil;
A first switching element that is triggered when the positive induced voltage of the trigger coil reaches a predetermined trigger level and becomes conductive to supply the charge of the ignition charge/discharge capacitor to the ignition coil. In the contact ignition device, a second switching element is provided which is triggered and conducts when the negative induced voltage of the exciter coil reaches a predetermined trigger level, and short-circuits the positive induced voltage of the trigger coil. The first switching element is configured such that during forward rotation, the first switching element is triggered before the second switching element, and when the internal combustion engine is reversed, the second switching element is triggered before the first switching element. A non-contact ignition system for an internal combustion engine, characterized in that a trigger level of a switching element and a second switching element is set.
