ABSTRACT:
A control apparatus includes an air-fuel ratio sensor for detecting an oxygen content over a wide range of operating conditions from a light load operation to a high load operation of an engine and the sensor is utilized so as to establish the desired air-fuel ratio such that the air-fuel ratio (.lambda.) becomes .lambda.>1, .lambda.=1 or .lambda.<1, respectively in the light, intermediate or high load operating region of the engine and the output of the air-fuel ratio sensor is utilized so as to feedback control the air-fuel ratio over the wide range of operating conditions and thereby maintain the desired air-fuel ratio in each of the operating regions.
