摘要： In an exhaust gas purification system, including a catalyst unit carrying an NOx occlusion-reduction type catalyst, a first-stage rich control having a target air-fuel ratio lower than theoretical air-fuel ratio and which is conducted through addition of an amount of a reducing agent meeting an amount of oxygen emitted in the initial stage of regeneration control. In the first-stage rich control a completion of oxygen emission is judged on the basis of an oxygen concentration on the downstream side of the catalyst unit. Upon determination of the completion of the oxygen emission, a later-stage rich control close to the theoretical air-fuel ratio with the target air-fuel ratio increased over that of the first-stage rich control is conducted to thereby accomplish regeneration of the catalyst unit. As a result, there can be prevented not only any outflow of unpurified NOx occurring in the initial stage of regeneration but also any outflow of virgin reducing agents, such as HC and CO, occurring in the later stage of regeneration.

摘要： In an NOx purification system and a method for control of the NOx purification system, two oxidation catalysts are provided upstream of an ammonia solution supply unit, and the in-cylinder fuel injection is so controlled that hydrocarbon in exhaust gas is mainly oxidized by the upstream oxidation catalyst and nitric oxide in the exhaust gas is mainly oxidized by the downstream oxidation catalyst. In the purification of NOx in the exhaust gas by feeding an ammonia solution for NOx reduction to a selective reduction NOx catalyst, this technique enables the system to adjust the concentrations of HC, NO and NO2 in the exhaust gas flowing into the selective reduction NOx catalyst to proper values so as to purify the NOx efficiently by the selective reduction NOx catalyst. The NOx purification performance in a lower temperature range can be thus improved.

摘要： In an exhaust gas purifying system (1) which is equipped with a NOx occlusion reduction type catalyst (11) and an oxidation catalyst (12) set on the upstream side of the catalyst (11) and in which sulfur purge control for regenerating the sulfur-poisoned catalyst (11) is conducted, in conducting the sulfur purge control, the air fuel ratio control for sulfur purge is conducted after the temperature difference (ΔTIO) between the inlet side and outlet side of the catalyst (11) has been reduced to a prescribed level (ΔT0) or below by raising the exhaust temperature. According to the invention, the sulfur poison on the catalyst (11) can be uniformly removed in the sulfur-purge regeneration control, whereby the service life of the catalyst (11) can be protected from being shortened by sulfur poisoning. Further, the catalyst (11) can be protected from the thermal deterioration caused by partial temperature rise inside the catalyst (11) on its downstream side, so that the service life of the catalyst (11) can be protected from being shortened by thermal deterioration.
