とを特徴とする空燃比制御装置。An oxygen sensor detects the oxygen concentration in the engine exhaust gas and outputs a sudden change in voltage at an air-fuel ratio according to the value of the injected current, and an oxygen sensor that intermittently injects current at a predetermined period so that the oxygen sensor output voltage reaches a predetermined voltage. A current supply means, a peak value detection means for detecting the peak value of the injected current that is intermittently supplied, and a feedback control means for controlling the air-fuel ratio based on the output of the peak value extraction means. An air-fuel ratio control device characterized by:
