摘要： A method of controlling a choke valve of an engine with a controller is disclosed. Also disclosed is an automatic choke performing the method, an engine having the automatic choke, and an apparatus having the engine. The controller includes an electronic circuit, such as a programmable device, and is coupled to a temperature sensor and a motor. The method includes determining a temperature value using the temperature sensor, determining a time period to hold the choke valve in a first position, keeping the choke valve at the first position for the time period, moving the choke valve from the first position toward a second position using the motor, determining a count to hold the choke valve, keeping the choke valve at the second position for the count, and moving the choke valve from the second position toward a fully open position.

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

摘要： An automatic choke apparatus for use in an internal combustion engine. The choke apparatus includes a choke valve automatically operable in response to the speed of the engine, a thermally conductive assembly that conducts heat from exhaust gases produced by the engine, a thermally responsive member in thermal communication with the thermally conductive assembly, and a mechanism that moves in response to the thermally responsive member to cause the choke valve to remain in at least a partially open position during engine starting when the thermally responsive member senses a temperature above a predetermined temperature. The thermally conductive assembly at least partially surrounds the path of the exhaust gases.
