Abstract: 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.

Abstract: A moisture adsorbing device 1 comprising a type Y zeolite, and an NOx adsorbing device 2 being put in place on an exhaust-gas downstream side of the moisture adsorbing device 1, and comprising a zeolite that includes a transition metal ion in the cation exchange sites are included. In NOx adsorbing apparatuses, since the less the moisture content in exhaust gases is the more the NOx adsorbing capability improves, the NO adsorbing capability in low-temperature region is improved especially by means of the combination with a moisture adsorbing device that comprises a type Y zeolite whose Al2O3 proportion is great and whose moisture adsorbing amount is great compared with the other zeolites.

Abstract: A method for remediating a NOx-containing lean diesel emission includes providing a LNT/SCR catalyst system including a SCR catalyst and a first and second LNT. The SCR catalyst is disposed downstream of the second LNT which is disposed downstream of the first LNT. The lean NOx-containing diesel emission is introduced to the first LNT with the NOx being absorbed on to the first LNT forming a substantially NOx-free lean diesel emission. An exotherm generating agent is introduced to the substantially NOx-free diesel emission between the first LNT and the second LNT to form a reactive lean diesel emission. The reactive lean diesel emission is introduced to the second LNT generating a quantity of heat effective for desorbing absorbed NOx. A reducing agent is introduced into the desorbed NOx between the second LNT and SCR catalyst. The desorbed NOx diesel emission is remediated in the SCR catalyst.

Abstract: In a NOx purification system 1 provided with a NOx occlusion reduction catalyst 20 and a control unit 30 which executes a NOx regeneration control and a sulfur poisoning regeneration control, a binary λ sensor 26 and a reducing agent concentration sensor 25 for detecting a concentration of the reducing agent are disposed downstream of the NOx occlusion reduction catalyst 20. The level of deterioration of the NOx occlusion reduction catalyst 20 caused by sulfur poisoning is estimated on the basis of a time period Ta from a time point T3 at which a marked decrease of oxygen concentration is detected by the binary λ sensor 26 to the time point T2 at which the marked increase of the oxygen concentration is detected by the reducing agent concentration sensor 25 under the NOx regeneration control. Accordingly, the sulfur poisoning amount is accurately estimated and by performing the sulfur poisoning regeneration at an appropriate frequency, any excessive sulfur poisoning regeneration can be avoided, thereby preventing deterioration of mileage.
