Abstract
A control system for the choke valve of a caburetor employs a bimetal element heated by an electric resistance heater when the engine is running to move the choke valve toward open position. A vacuum actuator is connected to move the choke valve toward open position when manifold vacuum pressure develops upon starting of the engine. Linkage connects the throttle valve to an unloader device which insures that the choke valve is held open when the throttle valve is opened beyond a predetermined limit. A temperature responsive device subjected to a flow of engine coolant or lubricant operates a fast idle device which holds the throttle valve at fast idle position and allows it to return to slow idle position only when the engine coolant or lubricant has been heated to a sufficient extent. The fast idle device is connected through linkage to prevent closing movement of the choke valve in the event that the engine is stopped in hot condition, thereby facilitating re-starting of the engine while hot.
