    • A method of detecting deterioration of an exhaust gas ingredient concentration sensor for use in controlling an air-fuel ratio of a mixture supplied to an internal combustion engine having an exhaust system in which the sensor is arranged. The sensor has an output characteristic approximately proportional to concentration of a specific ingredient in exhaust gases emitted from the engine. The air-fuel ratio is feedback-controlled to a desired air-fuel ratio by calculating an amount of fuel supplied to the engine by the use of a desired air-fuel ratio coefficient indicative of the desired air-fuel ratio and set in dependence on operating conditions of the engine, and an air-fuel ratio correction coefficient set in dependence on a value of an output from the sensor and the desired air-fuel ratio coefficient. A plurality of average values of the air-fuel ratio correction coefficient are calculated, respectively, when the desired air-fuel ratio falls within a plurality of predetermined ranges. The average values thus calculated are compared with each other. A degree of deterioration of the sensor is determined from results of the comparison. Further, a method of feedback-controlling the air-fuel ratio in the above-mentioned manner, in which the value of the output from the sensor is corrected in response to the degree of deterioration thus determined.

    • An air-fuel ratio control method for an internal combustion engine. An amount of fuel to be supplied to the engine is calculated in response to operating conditions of the engine and output from an exhaust gas ingredient concentration sensor, to thereby feedback-control the air-fuel ratio of a mixture supplied to the engine to a desired air-fuel ratio. The method comprises the steps of (1) calculating a fuel cooling correction value for compensating for a change in an actual air-fuel ratio caused by cooling effects of actually-injected fuel, according to at least one parameter which can determine the amount of fuel to be supplied to the engine, and (2) calculating the amount of fuel to be supplied to the engine by the use of the fuel cooling correction value.
