Engine with an automotic choke and method of operating an automatic choke for an engine

摘要

An automatic choke (240) connectable to an engine (100. Also disclosed is an engine (100) including the automatic choke (240), an apparatus including the engine (100) and the automatic choke (240), and a method of controlling a choke valve (115). The automatic choke (240) includes a motor (145) for moving a choke valve (115) and a controller (150) electrically connected to the motor (145). In one construction, the controller (150) is configured to store position information and a flag related to a position of the choke valve (115), determine the engine (100) has stopped, and control the automatic choke (240) with the stored position information based on the flag and the determination that the engine (100) has re-started. In another construction, the controller (150) is configured to generate a motor control signal to direct the choke valve (115) to a fully-open position without providing choke relief based on a temperature value indicating the engine temperature is greater than a threshold.
