Abstract
An automatic choke system has a thermostatic spring connected to a choke valve, and a heater for heating the thermostatic spring so as to open the choke valve. A control circuit is provided for controlling the current passing through the heater. At starting of an engine, when cooling water temperature is lower than a predetermined temperature the control circuit operates to decrease the current so as to slowly open the choke valve. When the cooling water temperature is higher than a predetermined temperature, a rated current is supplied to the heater so as to quickly open the choke valve.
