摘要： In an internal combustion engine, an SOx sensor (16) having a sensor part (53, 60) trapping the SOx contained in the exhaust gas and able to detect the amount of SOx trapped at the sensor part (53, 60) from a change of property of the sensor part (53, 60) is arranged in the engine exhaust passage upstream of the NOx storing catalyst (14). When estimating the amount of SOx stored in the NOx storing catalyst (14) from the amount of SOx trapped at the sensor part (53, 60), deviation of the estimated value of the amount of stored SOx arising due to the difference between the SOx trapping rate of the sensor part (53, 60) and the SOx trapping rate of the NOx storing catalyst (14) is corrected.

摘要： In an internal combustion engine, the engine is formed so that an output of an electric motor can be superposed on an output of the engine. In the engine exhaust passage upstream of the NOX storage catalyst, an SOX trap catalyst able to trap the SOX contained in the exhaust gas is arranged. When regenerating the SOX trap catalyst, the vehicle drive power from the engine and the vehicle drive power from the electric motor are adjusted so that the SOX concentration in the exhaust gas flowing out from the SOX trap catalyst becomes less than a predetermined SOX concentration during the regeneration period.

摘要： In the present exhaust purification system of an internal combustion engine, a particulate filter is arranged downstream of an NOx storage/reduction catalyst device and an S trap device is arranged upstream of the NOx storage/reduction catalyst device. A first fuel supplying device for supplying additional fuel for regeneration of the particulate filter to the exhaust system upstream of the S trap device or into the cylinder is provided. An amount of the additional fuel supplied by the first fuel supplying device is controlled to make the S trap device not release SOx. A second fuel supplying device is provided in the exhaust system between the NOx storage/reduction catalyst device and the particulate filter to make up for a deficiency of the additional fuel supplied by the first fuel supplying device in the regeneration treatment of the particulate filter.

摘要： In an internal combustion engine, a sulfur detection sample gas is generated in a sample gas generation chamber by fuel of an amount smaller than the amount of fuel fed to a combustion chamber and proportional to the amount of fuel fed to the combustion chamber. An SOx sensor having a sensor part trapping the sulfur contained in the sample gas and capable of detecting the amount of sulfur trapped in the sensor part from the property changes of the sensor part is provided. The amount of SOx that flows into the catalyst is estimated from the output value-of this SOx sensor.

摘要： In an internal combustion engine, an NOx selective reducing catalyst is arranged inside an engine exhaust passage, an oxidation catalyst is arranged upstream of the NOx selective reducing catalyst, and an NOx adsorption catalyst is arranged upstream of the oxidation catalyst. The NOx adsorption catalyst has a property of releasing NOx when the temperature rises and a property of trapping the SOx contained in the exhaust gas. The inflow of SOx into the oxidation catalyst is suppressed by the NOx adsorption catalyst to prevent the NO released from the NOx adsorption catalyst being oxidized to NO2 at the oxidation catalyst from being obstructed by SOx.

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.
