Abstract:
An engine including an automatic choke that includes a choke valve movable between a fully closed position and a fully open position, a temperature sensor coupled to the engine and operable to provide a temperature signal indicative of a temperature of the engine, and a motor connected to the choke valve and operable to move the choke valve in response to a motor control signal. A controller is electrically connected to the motor and to the temperature sensor. The controller includes an electronic circuit having a memory. A table includes engine specific choke position data stored in memory, wherein the controller determines a choke initial position based on the temperature of the engine and the choke position data, and wherein the motor moves the choke valve toward that position in response to an attempt to start the engine.
