ABSTRACT:
Disclosed is a basic air-fuel ratio adjustment method and an apparatus for an internal combustion engine. The adjustment of the basic air-fuel ratio is performed by measuring a signal level corresponding to the level of an air-fuel ratio compensation signal of the engine while the feedback control operation for compensating an error of the air-fuel ratio of the engine is being stopped, by measuring the average level of the air-fuel ratio compensation signal when the feedback control is in operation, and by adjusting the means for presetting the basic air-fuel ratio of the air-fuel mixture fed into the engine so that the difference between the measured signal level and the measured average signal level becomes equal to a predetermined value. Thus, the adjustment of the basic air-fuel ratio can be very easily performed. Furthermore, a high accuracy of the adjustment can be easily obtained.
