ABSTRACT:
A temperature of an oxygen concentration detector generating an electromotive force according to a difference between oxygen concentration in an engine exhaust gas and oxygen concentration in the atmosphere, is detected, and coefficients in a transformation for converting the electromotive force to a value having a characteristic linear to an air-fuel ratio is modified according to the temperature.
