Kind Code:

B2

Abstract:

An air/fuel ratio control system is constructed to calculate a base value of an air/fuel ratio control in response to a plurality of engine operational parameters. The base value is adjusted by an output signal of an exhaust gas component concentration sensor, to provide an output value which is directly used for the air/fuel ratio control. Under a predetermined operational condition of the engine, the adjustment of the base value on the basis of the output signal of the exhaust gas component concentration sensor is stopped and the base value is corrected by a correction value, which is one of a number of values stored correspondingly as engine operational parameters, and read out using present values of the engine operational parameters.
