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： An engine comprising an exhaust passage having therein a NO x absorbent which absorbs the NO x when the air-fuel ratio of the exhaust gas flowing into the NO x absorbent is lean and releases the absorbed NO x when the air-fuel ratio of the exhaust gas flowing into the NO x absorbent becomes the stoichiometric air-fuel ratio or rich. When the air-fuel ratio of the air-fuel mixture should be changed over from lean to the stoichiometric air-fuel ratio, the air-fuel ratio of the air-fuel mixture is temporarily made rich and is then made the stoichiometric air-fuel ratio.

摘要： An exhaust purification device of an engine having an exhaust passage, comprising: a NOx absorbent arranged in the exhaust passage; air-fuel ratio control means for controlling the air-fuel ratio of the exhaust gas flowing into the NOx absorbent to temporarily change the air-fuel ratio of the exhaust gas flowing into the NOx absorbent from lean to rich at certain time intervals to release NOx from the NOx absorbent; deterioration detecting means for detecting the degree of deterioration of the NOx absorbent; wherein the relationship between the degree of deterioration of the NOx absorbent and a rich time period during which the air-fuel ratio of the exhaust gas flowing into the NOx absorbent is made rich is stored in advance, and said air-fuel ratio control means controls said rich time period on the basis of said stored relationship to shorten said rich time period as the degree of deterioration of the NOx absorbent becomes higher.

摘要： An exhaust gas purification system includes a transition metal/zeolite first catalyst (6), a three-way second catalyst (8), and a noble metal-type third catalyst (10) arranged in that order in the direction of exhaust gas flow in an exhaust conduit (4) of an internal combustion engine (2) capable of fuel combustion at lean air-fuel ratios. NOx which has not been purified by the transition metal/zeolite first catalyst (6) is oxidized by the three-way second catalyst (8) into NO2, which the noble metal-type third catalyst (10) can easily decompose into N2 and O2.
