に接続されていることを特徴とする内燃機関停止装置。A current limiting element is connected between an engine stop thyristor connected in parallel to the power supply coil with its anode directed toward the other end of the power supply coil of the ignition device for an internal combustion engine whose one end is grounded, and the gate cathode of the thyristor. an engine stop capacitor that is connected to the internal combustion engine and is charged by a voltage drop across the gate cathode of the internal combustion engine; a self-resetting manual stop switch that is closed when the internal combustion engine is stopped; and when the manual switch is closed. An internal combustion engine stopping device comprising a trigger circuit that provides an ignition signal to the thyristor,
The trigger circuit includes a coupling circuit that couples the other end of the exciter coil to a connection point between the capacitor and the current limiting element via a unidirectional element, and a current flowing through the coupling circuit to the capacitor side when electrical conduction occurs. The manual switch includes a transistor whose emitter is grounded so as to prevent the exciter from being supplied with a base current, and a base current supply circuit which supplies a base current to the transistor from the other end of the exciter coil. A diode is connected in parallel to the base emitter of the transistor so as to short-circuit the base and emitter of the transistor, and a diode with an anode directed toward the gate of the thyristor is connected to both ends of the current limiting element. Characteristic internal combustion engine stop device.
