Abstract
An automatic choke apparatus for a carburetor includes an electric actuator, a choke valve opening/closing mechanism configured to open and close a choke valve by being driven by a power exerted by the electric actuator, and a controller configured to control operation of the electric actuator. The controller, to which a battery supplies electric power, operates the electric actuator and the choke valve opening/closing mechanism in order that, when the engine is stopped, the choke valve is set in a semi-opened position and, when the engine starts to be cranked, the choke valve is set in a fully-closed position. Accordingly, it is possible to prevent the choke valve from freezing up in the fully-closed state in a case where the engine is stopped under an extremely low temperature environment.
