自動チヨーク装置。 A negative pressure-operated cam breaker is used that forcibly rotates the cam that closes the throttle valve to the idle position when the engine warms up to the set temperature in conjunction with the opening of the throttle valve, and closes the throttle valve to the specified opening. In the automatic cranking device for a carburetor, a diaphragm spring that acts against a negative pressure on a diaphragm that rotates the cam of the cam breaker is made of a shape memory alloy, and the diaphragm spring is made of a shape memory alloy. An automatic chiyoke device that is formed to be in an expanded state when the temperature is below and to be in a contracted state when the temperature is above a specified temperature.
