内燃機関停止装置。[Claims for Utility Model Registration] An oil level detection switch that closes when the oil level of an internal combustion engine falls below the permissible lower limit level, and an alternating current voltage that is induced in synchronization with the rotation of the internal combustion engine to output one half cycle. an engine stop thyristor connected to both ends of a power supply coil that drives an ignition device for an internal combustion engine in such a way that the output voltage of the one half cycle becomes a forward voltage; An internal combustion engine stopping device comprising a trigger circuit that supplies a trigger signal to a gate of an engine stopping thyristor to make the engine stopping thyristor conductive, wherein the trigger circuit is connected between an anode gate of the engine stopping thyristor. A series circuit of a resistor and a capacitor, and a collector-emitter circuit are connected in parallel to the gate cathode of the engine stop thyristor, and a base current is applied from the power supply coil through the capacitor to establish conduction. a trigger control transistor switch having a base coupled to the capacitor and allowing a trigger signal to be supplied from the power supply coil to the thyristor through the capacitor and the resistor when in a cut-off state; An internal combustion engine stopping device characterized in that an oil level detection switch is connected between the base and emitter of the trigger control transistor so as to cut off the trigger control transistor switch when the oil level detection switch is closed.
