摘要翻译： 公开了一种催化剂和净化废气的方法。 催化剂包括多孔载体，负载在多孔载体上的Pt和/或Pd，以及负载在其上并能够与废气中所含的NO x和SO 2反应的至少两种成分，形成硝酸盐和复合硫酸盐。 由于所得复合硫酸盐在贫氧气氛（即富燃料气氛）中可能在低温下分解，所以催化剂可以吸收更多的NO x。 因此，催化剂可以净化更多的NOx。 此外，选自过渡元素的第二种成分可代替两种助催化剂中的一种。 此外，即使进行苛刻的耐久性试验，催化剂也具有优异的NOx净化性能。 在该过程中，使催化剂与富氧废气接触，其中氧浓度为氧化其中被氧化的组分所需的化学计量点或更多。

摘要： A control apparatus for an internal combustion engine provided with a zeolite catalyst (6) capable of reducing NOx under oxidizing gas conditions includes an engine speed detecting sensor (11), an EGR control means (13), and an air-fuel ratio control means (16). The EGR control means (13) includes an EGR valve opening degree calculating means (15) for calculating an EGR valve opening degree based on air-fuel ratios which cause a current exhaust gas temperature to be in a predetermined temperature range at engine speeds lower than a predetermined engine speed and calculating an EGR valve opening degree which causes an amount of large molecular weight HC components in the exhaust gas to be more than a predetermined amount at engine speeds equal to or higher than the predetermined engine speed. The air-fuel ratio control means (16) includes an air-fuel ratio setting means (18) for setting a current air-fuel ratio to a lean air-fuel ratio calculated based on the EGR valve opening degree.

摘要： A device for detecting deterioration of a NOx absorbent arranged in the exhaust passage of an engine. An O2 sensor generating a current proportional to the air-fuel ratio is arranged in the exhaust passage downstream of the NOx absorbent. When the amount of NOx absorbed in the NOx absorbent is almost zero or after the amount of NOx absorbed in the NOx absorbent is made almost zero, the air-fuel ratio of the air-fuel mixture is changed from lean to rich, and the amount of oxygen stored in the NOx absorbent is detected from the output signal of the O2 sensor at this time. Further, the NOx absorbing capability is found by using this detected oxygen amount.

摘要： A device for detecting deterioration of a NO x absorbent arranged in the exhaust passage of an engine. An O 2 sensor generating a current proportional to the air-fuel ratio is arranged in the exhaust passage downstream of the NO x absorbent. When the amount of NO x absorbed in the NO x absorbent is almost zero or after the amount of NO x absorbed in the NO x absorbent is made almost zero, the air-fuel ratio of the air-fuel mixture is changed from lean to rich, and the amount of oxygen stored in the NO x absorbent is detected from the output signal of the O 2 sensor at this time. Further, the NO x absorbing capability is found by using this detected oxygen amount.
