摘要： In an internal combustion engine, a pair of NOx storing catalysts are arranged in series in an engine exhaust passage. When causing the upstream NOx storing catalyst to release NOx and store the released NOx in the downstream NOx storing catalyst, the oxygen concentration in the exhaust gas is temporarily reduced in a state where the exhaust gas is maintained at a lean air-fuel ratio. As opposed to this, when releasing NOx from the upstream NOx storing catalyst and the downstream NOx storing catalyst and reducing the NOx, the air-fuel ratio of the exhaust gas is temporarily switched from lean to rich.

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： A NOx storing catalyst (11) comprising a precious metal catalyst (46) and NOx absorbent (47) is arranged in an exhaust passage. When the air-fuel ratio of the exhaust gas is lean, the storing catalyst cold stores the NO2 contained in the exhaust in the absorbent when the catalyst is inactive and hot stores the cold stored NO2 in the absorbent when the catalyst is made active. The NO2 contained in the exhaust is cold stored in the absorbent when the catalyst is not activated, and when a predetermined NOx storing catalyst restoring condition (107) is met, a NOx storing catalyst restoring control (109, 115) including raising the NOx storing catalyst temperature to a predetermined temperature to active it (109) is executed so as to restore the cold storing capability of the NOx absorbent.

摘要： The problem is to regenerate the purification ability of an exhaust gas purification device more reliably or efficiently in an exhaust gas purification system that combines a plurality of branch passages branch off from an exhaust gas passage and exhaust gas purification devices. When the purification ability of an exhaust gas purification device is regenerated, in the branch passage where the exhaust gas purification device is provided whose purification ability is to be regenerated, the opening angle of an exhaust gas flow volume control valve is set to the minimum opening angle that can reliably transport a reducing agent that is added from a reducing agent addition section. While the opening angle is maintained, the reducing agent is added. After the addition of the reducing agent is complete, the opening angle of an exhaust gas flow volume control valve is closed completely.

摘要： An SOX trap catalyst 12 and NOX purification catalyst 13 are arranged in an engine exhaust passage. A substrate 50 of the NOX purification catalyst 13 is formed with a coat layer comprised of at least the two layers of an upper coat layer 51 and a lower coat layer 52. The lower coat layer 52 is formed from an NOX storage catalyst storing the NOX contained in the exhaust gas when the air-fuel ratio of the exhaust gas is lean and releasing the stored NOX when the air-fuel ratio of the exhaust gas is a stoichiometric air-fuel ratio or rich. The upper coat layer 51 is formed from a material of a weaker basicity than this NOX storage catalyst.

摘要： In an internal combustion engine, a first exhaust passage and second exhaust passage branched from an exhaust passage are provided. An NOx storing reduction catalyst and a particulate filter are arranged in each exhaust passage. For example, when NOx should be released from the NOx storing reduction catalyst in the first exhaust passage, fuel is added from a fuel addition valve in the state with exhaust gas allowed to flow into only the first exhaust passage, while when the added fuel sticks to the NOx storing reduction catalyst, the first exhaust control valve is temporarily closed and the exhaust gas is made a rich air-fuel ratio.
