摘要： In an internal combustion engine, an NOX selective reducing catalyst (15) is arranged in an engine exhaust passage. Aqueous urea is fed from an aqueous urea feed valve (17) into the NOX selective reducing catalyst (15) to selectively reduce the NOX contained in the exhaust gas with the ammonia generated from the aqueous urea. The moisture contained in the exhaust gas is recovered and stored in a water tank (21). It is provided with a high concentration aqueous urea tank (22) storing high concentration aqueous urea having a higher urea concentration than the urea concentration of the aqueous urea fed to the NOX selective reducing catalyst (15), and the high concentration aqueous urea is diluted with the recovered moisture thereby generating aqueous urea fed to the NOX selective reducing catalyst (15).

摘要： A technique is provided which is capable of completing SOx poisoning recovery control on a NOx storage reduction catalyst in a shorter period of time. In the course of the SOx poisoning recovery control, the degree of decrease of a SOx release speed resulting from a decrease in an amount of SOx occlusion of the NOx catalyst (the degree of decrease of the SOx release speed (Ddw)) with respect to that at the time of start of the SOx poisoning recovery control is estimated. In accordance with the increasing degree of decrease of the SOx release speed (Ddw), a catalyst bed temperature (Tc) is caused to rise up to a higher side target temperature (Tct), and at the same time an exhaust gas air fuel ratio (A/F) is caused to lower up to a richer side target air fuel ratio (A/Ft), whereby the SOx release speed Vsox during the SOx poisoning recovery control is suppressed from lowering.

摘要： A NOx absorbent is arranged in an exhaust passage of an internal combustion engine, and a fuel supply valve (28) is arranged in the exhaust passage upstream of the NOx absorbent. If the temperature of the NOx absorbent is lower than a predetermined temperature when the NOx must be released from the NOx absorbent, the air-fuel ratio of exhaust gas flowing through the NOx absorbent is first switched from a basic lean air-fuel ratio to and maintained at a lean air-fuel ratio with a lower leanness for a predetermined lean time, and is then switched to a rich air-fuel ratio. If the temperature of the NOx absorbent is higher than the predetermined temperature when the NOx must be released from the NOx absorbent, the air-fuel ratio of the exhaust gas flowing through the NOx absorbent is switched to the rich air-fuel ratio without being switched to the lean air-fuel ratio with a lower leanness.
