摘要： An internal combustion engine in which an SOx trapping catalyst (12) and particulate filter (13) are arranged in a engine exhaust passage and in which a recirculation exhaust gas takeout port (17) is formed in the engine exhaust passage downstream of the particulate filter (13). Inside the engine exhaust passage downstream of the recirculation exhaust gas takeout port (17), an NOx storing catalyst (15) and a reducing agent feed valve (21) are arranged. When NOx should be released from the NOx storing catalyst (15), reducing agent is fed into the exhaust passage from the reducing agent feed valve (21).

摘要： HC feed control for feeding HC into exhaust gas upstream of an SOx trap 11 when a predetermined condition stands is executed. When an SOx trap amount is smaller than a predetermined amount, as HC feed control, first HC feed control feeding HC into the exhaust gas upstream of the SOx trap by a predetermined pattern is executed. When the SOx trap amount is larger than a predetermined amount, as HC feed control, second HC feed control feeding HC into the exhaust gas upstream of the SOx trap by a pattern different from the predetermined pattern, which pattern keeping the temperature of the SOx trap from locally becoming higher than the predetermined temperature or suppressing the formation of a region in the exhaust gas flowing into the SOx trap where the air-fuel ratio becomes locally rich, is executed.

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 means 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 means is controlled to make the S trap device not release SOx. A second fuel supplying means 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 means in the regeneration treatment of the particulate filter.

摘要： An SOX trap catalyst (11) in which at least one of an alkali metal and alkali earth metal is carried diffused is arranged in an exhaust passage of an internal combustion engine. By holding the temperature of the SOX trap catalyst (11) during engine operation at the temperature where a nitrate of the at least one of the alkali metal and alkali earth metal becomes the melted state, a nitrate movement and coagulation action where the nitrate in the SOX trap catalyst (11) moves to and coagulates at the surface of the SOX trap catalyst (11) is promoted. Due to this nitrate movement and coagulation action, SOX is removed while restoring the SOX trap rate.

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.
