ABSTRACT:
In a system which detects the condition of an exhaust gas of an internal combustion engine by an exhaust gas sensor and corrects the rate of fuel supply in a feedback control mode, on the basis of the detected condition, the rate of fuel supply is corrected, in response to a particular output of the exhaust gas sensor indicating an optional air-to-fuel ratio of the fuel supply, to a rate of the past fuel supply which occurred at a dead time before detection of the particular output of the sensor, the dead time being corresponding to a time required for a fuel fed into the air inlet pipe to be burned up and then its exhaust gas to reach the sensor.
