ABSTRACT:
The combination of a fuel supply system for an internal combustion engine, an exhaust gas oxygen concentration sensor and a feedback control system including an integration circuit connected to the fuel supply system and a correction control circuit connected to the exhaust gas oxygen concentration sensor and the integration circuit. The combination controls the air-fuel mixture to be supplied to an engine in accordance with an integration output signal, which in turn is generated from the output signal generated by the exhaust gas oxygen concentration sensor. The correction control circuit serves to disconnect the exhaust gas oxygen concentration sensor from the integration circuit when a predetermined operating condition of the engine is reached, thereby holding the output from the integration circuit constant.
