Exhaust purification catalyst device for internal combustion engine |
| abstract |
(57) [PROBLEMS] An exhaust gas purifying catalyst that reliably removes a purifying ability without deteriorating the operating state of an internal combustion engine even if a purifying substance other than nitrogen oxides (NOx) adheres. Provided is an exhaust purification catalyst device capable of maintaining the function of a (NOx catalyst). SOLUTION: Attachment amount estimating means (S10) for estimating the attachment amount of the purification performance reducing substance attached to the exhaust gas purification catalyst, and when the attachment amount estimated by the attachment amount estimation means reaches a predetermined attachment amount (S12). Catalyst temperature raising means for performing temperature control of combustion gas in the internal combustion engine to raise the temperature of the exhaust purification catalyst, wherein the catalyst temperature raising means corrects the ignition timing of the internal combustion engine to a retard side. A timing correction means (S24) and an intake air amount correction means (S26) for increasing the intake air amount to the internal combustion engine when the ignition timing is retarded are included. |
