Claims

[Scope of utility model registration request]

(1) A stop device for an internal combustion engine that includes a power generation coil that generates power by driving the internal combustion engine, and ignition voltage generating means that generates an ignition voltage for the internal combustion engine by controlling a current flowing through the power generation coil; a rectifier circuit for rectifying the output of the generator coil; an instantaneous return switch for stopping the internal combustion engine; a thyristor receiving the output of the rectifying circuit and triggered by pressing the instantaneous return switch; and a conduction period of the thyristor. A stopping device for an internal combustion engine, comprising short-circuiting means for short-circuiting both ends of the generator coil at least at the center during a period during which the ignition voltage is to be generated.

(2) the shorting means includes a semiconductor switching element;
A stopping device for an internal combustion engine according to claim (1) of the utility model registration.

(3) The output of the generator coil is an alternating current, the ignition means generates the ignition voltage in a positive half cycle or a negative half cycle of the alternating current output, and the short circuit means Utility model registration claim No.
The internal combustion engine stopping device according to item 1) or item (2).
