More Information
Summary:In an auto-choke system for a general-purpose engine, it is determined whether the operator has operated a combination switch to enable ignition in the engine and based on the result of this determination, the operation of a choke motor (actuator) is controlled to regulate the opening of the choke valve, specifically the operation of the choke motor is controlled to fully open the choke valve when ignition is found to be disabled. As a result, jetting of fuel is minimized and flooding prevented when the recoil starter is manipulated with ignition disabled. In addition, the operation of the choke motor is controlled to fully close the choke valve when ignition is found to be enabled, thereby enhancing the starting performance of the engine.
