  • Air-fuel ratio controller for internal combustion engine
    Patent number: 5115781
    Abstract: A relation with output characteristic of an oxygen density sensor corresponding to a deviation of an air fuel ratio of a mixed gas supplied actually to an internal combustion engine from a desired air fuel ratio is stored beforehand in an air fuel ratio controller of the present invention. Then, the air fuel ratio deviation is computed correspondingly to an actual output of the oxygen density sensor according to the stored relation, and an air fuel ratio controlled variable is corrected according to the computed air fuel ratio deviation, thereby controlling the air fuel ratio to the desired air fuel ratio.
