ABSTRACT:
Disclosed ia an air-fuel ratio control method and apparatus of an internal combustion engine. The control of the air-fuel ratio is accomplished by controlling the amount of fuel provided into the engine according to a plurality of separate electrical engine condition signals which indicate the operating condition of the engine, and according to an electrical air-fuel ratio correction signal which is determined in accordance with the air-fuel ratio of the engine. The value of at least one of the engine condition signals is corrected according to a signal which indicates a mean value of the air-fuel ratio correction signal. The correcting operation is executed so that the value of the mean value signal becomes nearly equal to a predetermined value which corresponds to the air-fuel ratio correction signal when a desired air-fuel ratio is obtained.
