Control is exercised to provide a rich target air-fuel ratio for the internal combustion engine during an oxygen release period between the instant at which the maximum oxygen storage state is detected and the instant at which the minimum oxygen storage state is detected later, and to provide a lean target air-fuel ratio for the internal combustion engine during an oxygen storage period between the instant at which the minimum oxygen storage state is detected and the instant at which the maximum oxygen storage state is detected later. Further, the amount of oxygen released from the catalyst during the oxygen release period or the amount of oxygen stored by the catalyst during the oxygen storage period is detected as an oxygen storage amount. The deterioration of the catalyst is then judged in accordance with the oxygen storage amount. Moreover, when exercising control for catalyst deterioration detection, the catalyst deterioration detection device sets up oxygen storage amount detection conditions for correcting a variation that may occur in the oxygen release period or the oxygen storage period depending on a difference in output detection conditions for the oxygen sensor. | 2009-11-26 |
