ABSTRACT:
A method of engine air/fuel ratio control using an oxygen concentration sensor producing a concentration-proportional output, in which a compensation value is computed for compensating a basic value such as a basic fuel injection time interval, and in which a deviation of an air/fuel ratio detected using the oxygen concentration sensor from a target air/fuel ratio is measured the compensation value is computed and updated only under the condition that the deviation is below a predetermined value, with the compensation value being determined in accordance with the amount of deviation.
