Next, until a time t5 when a second catalyst downstream air/fuel ratio sensor output Voxs2 changes to the rich ratio, the air/fuel ratio is controlled to that near the lower limit value of the window width obtained at the present time of the catalyst device which is narrowed according to the degree of deterioration of the catalyst device, and the maximum oxygen occluding amount CSCmax of the first catalyst is estimated.
