Abstract
PURPOSE:To set the position of a throttle valve to an adequate opening degree and improve the starting quality of an engine at the cold season, by using wax expanded and contracted in accordance with temperature, providing the built-in wax in an actuator and previously opening the throttle valve widely at the time of low temperature regardless of the closing with a key switch. CONSTITUTION:A throttle lever 202 of a carburetor 200 is operated by an actuator 100 through a throttle valve 201. The actuator 100 is controlled by a control circuit 300 and the control circuit 300 outputs signals from an ignition coil 500 and water temperature sensor 600 and a control signal in accordance with an idling state then controls the actuator 100. The actuator 100 is provided with a built-in wax 102, expansion-contraction operated in accordance with temperature, and the wax is contracted when temperature of a carburetor lowers then the actuator is moved toward a direction of opening of the throttle valve 201.
