摘要： The present invention is to provide a technique which can detect the level of degradation of a precatalyst in an exhaust gas purification system for an internal combustion engine that includes a NOx catalyst arranged on an exhaust passage of the internal combustion engine, and the precatalyst arranged on the exhaust passage at a location upstream of the NOx catalyst and having an oxidation function. In the present invention, the level of degradation of the precatalyst is detected based on the width of change in temperature of the NOx catalyst at the time when a reducing agent is intermittently supplied from an upstream side of the precatalyst to the precatalyst and the NOx catalyst. At this time, it is determined that the larger the width of change in temperature of the NOx catalyst, the higher the level of degradation of the oxidation catalyst is.

摘要： An exhaust emission purification device comprises a sulfur component holding agent arranged on the exhaust path of an internal combustion engine for holding a sulfur component, a NOx holding agent arranged downstream of the sulfur component holding agent in the exhaust gas for holding NOx and the sulfur components when the air-fuel ratio of the exhaust gas flowing thereinto is lean, and a reducing agent adding unit for adding a reducing agent to the exhaust gas flowing into the NOx holding agent. The concentration of the sulfur component contained in the reducing agent added by the reducing agent adding unit is lower than the concentration of at least the sulfur component contained in the fuel supplied to the combustion chamber of the internal combustion engine. Thus, the sulfur poisoning of the exhaust emission purifier can be avoided while at the same time reducing the fuel consumption rate.

摘要： A particulate filter (22) is arranged in an exhaust passage of an engine, while an exhaust throttle valve (45) is arranged in the exhaust passage downstream of the particulate filter (22). The exhaust throttle valve (45) is fully closed once, then fully opened cyclically. At that time, the flow velocity of the exhaust gas is increased for just an instant in a pulse-like manner, whereby masses of particulate are separated from the particulate filter 22 and discharged.

摘要： An exhaust purifying method and apparatus of an internal combustion engine are provided with an exhaust switch valve for switching a flow of exhaust gas flowing into an exhaust filter. By switching the exhaust switch valve, the exhaust gas is fed from one side and the other side of the filter, thereby stirring the soot (particulates) in the exhaust gas deposited on the filter having a NOx absorbent and an active-oxygen discharging agent supported thereon. Thus, the soot in the exhaust gas is continuously burned. Moreover, the switching of the exhaust switch valve and the rich spike are inhibited from being conducted simultaneously. In the case where the rich spike is conducted in order to discharge and reduce NOx absorbed in the NOx absorbent, the exhaust gas containing a large amount of HC and CO can be prevented from being discharged into the atmosphere without being purified.

摘要： An internal combustion engine having a lean NOx catalyst is capable of relieving a load upon an engine fuel injection device by eliminating the use of sub-injection, and of well purifying an exhaust gas and recovering from S-poisoning even by eliminating the use of the sub-injection. The internal combustion engine has a combustion heater for allowing a flow of combustion gas through an engine intake passageway to raise temperatures of engine related elements, a lean NOx catalyst, provided in an engine exhaust passageway, for purifying an engine exhaust gas, and a combustion gas introducing passageway for introducing at least some proportion of a combustion gas emitted by the combustion heater, toward upstream of the lean NOx catalyst in the engine exhaust passageway from the engine intake passageway when making a request for a reproducing process of the lean NOx catalyst.

摘要： An exhaust gas cleaning catalyst is formed of a carrier layer, and a noble metal catalyst and a SOx absorbing agent both carried on the carrier layer. The carrier layer of the exhaust gas cleaning catalyst includes at least a first distribution portion and a second distribution portion each having a different sulfate retention level. The sulfate retention level of the first distribution portion is lower than the sulfate retention level of the second distribution portion, and the noble metal catalyst is carried on the first distribution portion such that a SOx that has been oxidized on the noble metal catalyst diffuses toward the second distribution portion so as to be settled therein.
