摘要： In an exhaust purification system of an internal combustion engine of the present invention, a silver-alumina-based catalyst device and NOX reducing catalyst device are arranged in the engine exhaust system. When a temperature of the silver-alumina-based catalyst device becomes a first set temperature TI on the high temperature side, NOX released from the silver-alumina-based catalyst device is reduced by reducing material to be purified in the NOX reducing catalyst device. When the temperature of the silver-alumina-based catalyst device becomes a second set temperature on the low temperature side, NOX released from the silver-alumina-based catalyst device is reduced by reducing material to be purified in the NOX reducing catalyst device.

摘要： An SOx trap catalyst able to trap SOx contained in the exhaust gas is arranged in an engine exhaust passage upstream of an NOx storing catalyst in an internal combustion engine. When the SOx trap rate of the SOx trap catalyst falls, fuel is added in the exhaust gas flowing into the SOx trap catalyst to form in the SOx trap catalyst a region in which an air-fuel ratio becomes locally rich. SOx released from the SOx trap catalyst in this region can be trapped in the SOx trap catalyst at the downstream side once again without flowing out from the downstream end of the SOx trap catalyst.

摘要： A metal compound (50) able to trap a sulfur component in exhaust gas is arranged in a flow path of the exhaust gas, a property of the metal compound (50) changing along with an increase of the amount of sulfur component trapped at the metal compound (50) is measured, and the cumulative value of the amount of SOX actually contained in the exhaust gas is calculated from the measured property. On the other hand, the assumed cumulative value of the amount of SOX, assumed to be contained in the exhaust gas when assuming that fuel or oil of a sulfur concentration assumed in advance is used, is calculated. It is judged if fuel or oil with a high sulfur concentration is being used from the actual cumulative value of the amount of SOX and the assumed cumulative value of the amount of SOX.

摘要： An internal combustion engine in which a front end catalyst (12) and rear end catalyst (14) comprising NOx storing catalysts are arranged in an engine exhaust passage. When these catalysts (12, 14) should recover from SOx poisoning, SOx poisoning recovery proceeding is performed in which the temperatures of the corresponding catalysts (12, 14) are raised to the SOx release temperature and the air-fuel ratio of the exhaust gas flowing into the corresponding catalysts (12, 14) is made rich. In this case, the frequency of performing the SOx poisoning recovery proceeding of the rear end catalyst (14) is made higher than the frequency of performing the SOx poisoning recovery proceeding of the front end catalyst (12).

摘要： In an internal combustion engine, an NOx selective reduction catalyst (14) is arranged in an engine exhaust passage, and an NOx storage catalyst (12) is arranged in the engine exhaust passage upstream of the NOx selective reduction catalyst (14). When the amount of NOx stored in the NOx storage catalyst (12) exceeds a predetermined allowable value, the NOx storage catalyst (12) is raised in temperature to make the NOx storage catalyst (12) release the NOx. The amount of urea feed is decreased by exactly the amount of reduction of the calculated stored NOx amount with respect to the amount of urea feed determined from the engine operating state, and the amount of urea feed is increased by exactly the amount of reduction of the calculated released NOx amount with respect to the amount of urea feed determined from the engine operating state.
