を具備したことを特徴とする内燃機関安全装置。[Claims for Utility Model Registration] An ignition power supply short-circuit switch connected in parallel to an ignition power supply coil that provides ignition energy to an ignition device for an internal combustion engine with the output of one half cycle; In order to give a trigger signal from the ignition power supply coil to the ignition power supply short-circuit switch when a half-cycle output is generated,
A switch coil connected between one end of the ignition power supply coil and a trigger terminal of the ignition power supply short-circuiting switch transmits a trigger signal given to the ignition power supply short-circuiting switch when electrical continuity is established from the ignition power supply short-circuiting switch to the side. A self-holding thyristor that is connected via a resistor between the trigger signal bypass thyristor and the gate cathode of the trigger signal bypass thyristor and is charged by the voltage drop between the gate cathode of the thyristor. a capacitor; a neutral detection switch provided in a transmission provided between the internal combustion engine and a load and which assumes different states when the transmission is in a neutral position and in a position other than neutral; When the detection switch detects a neutral position, a current flowing from the ignition power source coil through the check yoke coil provides an ignition signal to the trigger signal bypass thyristor, and when the neutral detection switch detects a position other than neutral, An internal combustion engine safety device comprising: an ignition signal supply control circuit that prevents the ignition signal from being applied to the gate of the trigger signal bypass thyristor when the thyristor is activated.
