摘要： PROBLEM TO BE SOLVED: To provide a technology for restraining the catalytic deterioration, and restraining consumption of a reducing agent, caused by performing SOx poisoning recovery control, in an exhaust emission control device of an internal combustion engine. SOLUTION: When performing the SOx poisoning recovery control, when a catalytic deterioration degree of an NOx catalyst is low, the NOx catalyst is raised in the temperature to the relatively low temperature capable of discharging SOx of 580°C, and a surrounding atmosphere of the NOx catalyst is set to a high reduction atmosphere of the exhaust air-fuel ratio of A/F=13.0. As the catalytic deterioration degree of the NOx catalyst becomes large, the NOx catalyst is raised to the higher temperature (up to 700°C at the highest gradually from 580°C of the lowest), and the surrounding atmosphere of the NOx catalyst is set to a lower reduction atmosphere (the lowest reduction atmosphere of the exhaust air-fuel ratio A/F=14.5 gradually from the highest reduction atmosphere of the exhaust air-fuel ratio A/F=13.0).

摘要： PROBLEM TO BE SOLVED: To hold high NOx occluding capability of an NOx occlusion catalyst. SOLUTION: An SOx trap catalyst 11 capable of trapping SOx contained in an exhaust gas is arranged within an engine exhaust path at an upstream side of the NOx occlusion catalyst 12. When an SOx trap rate by the SOx trap catalyst 11 decreases, the SOx trap catalyst 11 is made to rise in temperature with an air-fuel ratio of the exhaust gas flowing into the SOx trap catalyst 11 kept lean. At this time, SOx trapped diffuses into an inside the SOx trap catalyst 11, so that the SOx trap rate recovers. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To properly reduce an oxide adsorbed in an NOx catalyst in the exhaust emission control system of an internal combustion engine having two NOx catalysts connected in series in an exhaust emission passage. SOLUTION: In this exhaust emission control system, when the oxide adsorbed in an upstream side NOx catalyst or a downstream side NOx is reduced, the ambient atmospheres of these NOx catalysts are alternately changed to a reducing atmosphere and an oxidizing atmosphere. When the ambient atmosphere of the downstream side NOx catalyst is changed to the reducing atmosphere, an exhaust emission air-fuel ratio on the upstream side of the upstream side NOx catalyst is lowered less than that in a case when the ambient atmosphere of the upstream side NOx catalyst is changed to the reducing atmosphere. Also, when the ambient atmosphere of the downstream side NOx catalyst is changed to the oxidizing atmosphere, a period in the oxidizing atmosphere is increased over that in a case when the ambient atmosphere of the upstream side NOx catalyst is changed to the oxidizing atmosphere.
