| abstract | (57) [Summary] [Problem] To converge to a stoichiometric air-fuel ratio with good response immediately after the air-fuel ratio feedback control condition is satisfied. SOLUTION: When an air-fuel ratio feedback control condition is satisfied, a calculation unit calculates a correction value for a basic control constant based on an output of a downstream air-fuel ratio sensor. In this case, the storage means 38 stores a correction value immediately before switching from when the air-fuel ratio feedback control condition is satisfied to when the air-fuel ratio feedback control condition is not satisfied, When the air-fuel ratio feedback control condition is not satisfied, the catalyst O 2 The measuring means 39 measures a parameter correlated with the storage amount, and thereafter, when the air-fuel ratio feedback control condition is satisfied, the output of the downstream air-fuel ratio sensor is returned to the stoichiometric air-fuel ratio in accordance with the parameter. The setting unit 40 sets a value obtained by correcting the stored value of the correction value as a correction value immediately after the air-fuel ratio feedback control condition is satisfied. |
