ABSTRACT:
Apparatus for automatically controlling the idle speed of an internal combustion automobile engine. A sensor senses the operating speed of the engine and develops an electrical signal representative thereof. Movement of a carburetor throttle valve from an open to a substantially closed position is sensed and an electrical signal indicative thereof is generated. Closure of the throttle valve indicates the engine is operating at idle. A controller is responsive to the second electrical signal to process the electrical signal from the sensor and generate an electrical control signal. The controller processes the electrical signal from the sensor means in accordance with a predetermined format based upon a transfer function derived for the engine. An electromechanical device is responsive to the control signal for moving the throttle valve to a desired position at which engine idle speed is a preselected speed determined in accordance with the transfer function.
