| titleOfInvention | Estimator for maximum oxygen storage capacity of catalyst |
| abstract | A method for obtaining a maximum oxygen storage amount with high accuracy in determining deterioration of a catalyst. The provisional maximum stored oxygen amount is calculated by accumulating the excess oxygen amount in a predetermined first period within the lean control period, and the excess unburned matter is determined in the predetermined second period within the rich control period. The provisional maximum released oxygen amount is calculated by integrating the amount of oxygen corresponding to the amount. This device calculates the provisional maximum oxygen storage amount based on the provisional maximum stored oxygen amount and the provisional maximum released oxygen amount, and the corrected provisional maximum oxygen storage amount obtained by correcting based on the provisional maximum oxygen storage amount is maximized. Acquired as oxygen storage amount. At this time, the present apparatus corrects the provisional maximum oxygen storage amount so that the corrected provisional maximum oxygen storage amount decreases as the provisional maximum oxygen storage amount decreases.
