ABSTRACT:
A system for regulating the idle speed of an internal combustion engine with an electronic fuel injection system having a bypass around a throttle valve of the engine and a solenoid operated control valve provided in the bypass to control the volume of air flow passing the bypass. The system comprises an engine speed sensor for sensing the engine speed of the engine and for producing an engine speed voltage, an idle switch responsive to idle operation of the engine for producing an idle signal, and a reference voltage circuit for producing a reference voltage corresponding to a predetermined idle speed. A first integrator is provided for integrating the difference between the engine speed voltage and the reference voltage and for producing a voltage. A control signal generating circuit is provided to be responsive to the voltage of the integrator for producing a positive going control signal and negative going control signal at upper limit and lower limit of the integrator output voltage. A second integrator is responsive to the positive going and negative going control signals to produce a control voltage. The control voltage is applied to a driver for energizing the solenoid of the solenoid operated control valve to actuate the control valve to regulate the idle speed to the predetermined idle speed.
