摘要： An exhaust gas purifying device for an engine comprises an exhaust gas purifying catalyst arranged in the exhaust passage. The catalyst is capable of reducing NO.sub.X in the catalyst in the oxidizing atmosphere, and comprises a reducing agent adsorbent adsorbing a reducing agent in the inflowing exhaust gas therein when the pressure in the adsorbent becomes higher, and desorbing the adsorbed reducing agent therefrom when the pressure in the adsorbent becomes lower. An exhaust gas control valve is disposed in the exhaust passage downstream of the catalyst. When both the engine load and the engine speed are low, the opening of the valve is made smaller to increase the pressure in the catalyst. At this time, hydrocarbon is fed to the catalyst, and is then adsorbed in the catalyst. When the engine load or the engine speed becomes high, or the cumulative amount of hydrocarbon fed to the catalyst becomes larger than a predetermined amount, the valve is made fully open to reduce the pressure in the catalyst. At this time, the adsorbed hydrocarbon is desorbed from the catalyst, and then reduces NO.sub.X in the catalyst.

摘要： According to the present invention, SO.sub.X in the exhaust gas of an internal combustion engine is absorbed by a sulfate absorbent which absorbs SO.sub.X in the exhaust gas when the temperature is lower than a releasing temperature and releases the absorbed SO.sub.X when the temperature becomes higher than the releasing temperature. When the exhaust gas temperature increases during the operation of the engine and reaches the releasing temperature, the temperature of the exhaust gas flowing into the sulfate absorbent is further raised to a predetermined temperature by supplying fuel to the exhaust gas passage upstream of the sulfate absorbent. The ratio of SO.sub.3 in the SO.sub.X mixture released from the sulfate absorbent changes in accordance with the temperature, and takes the highest value at a certain temperature (i.e., a peak temperature). Therefore, when the exhaust gas temperature is raised above the peak temperature, the ratio of SO.sub.3 in the SO.sub.X mixture released from the sulfate absorbent decreases as the temperature increases. In the present invention, the above-noted predetermined temperature is selected in such a manner that the ratio of SO.sub.3 at this predetermined temperature becomes lower than the ratio of SO.sub.3 at the releasing temperature. Therefore, when SO.sub.X is released from the sulfate absorbent, the amount of SO.sub.3, i.e., the amount of particulate matter released into the atmosphere can be maintained at a low level.
摘要翻译：根据本发明，内燃机废气中的SO x被吸收在温度低于脱模温度时吸收废气中的SO x的硫酸盐吸收剂，并且当温度变得高于释放温度。当发动机运转时排气温度升高并达到释放温度时，通过向硫酸吸收剂上游的排气通道供给燃料，进一步将流入硫酸盐吸收剂的废气升温至规定温度。从硫酸盐吸收剂释放的SO x混合物中的SO 3的比例根据温度而变化，并且在一定温度（即峰值温度）下获得最高值。因此，当废气温度升高到高于峰值温度时，从硫酸盐吸收剂释放的SO x混合物中的SO 3比随温度升高而降低。在本发明中，以这样的方式选择上述预定温度，使得在该预定温度下的SO 3的比例低于在释放温度下的SO 3的比例。因此，当SOX从硫酸盐吸收剂中释放出来时，SO 3的量，即释放到大气中的颗粒物质的量可以保持在较低水平。

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

摘要： A NO.sub.x absorbent (17) is disposed in an exhaust passage of an internal combustion engine. This NO.sub.x absorbent (17) absorbs the NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (17) is lean and releases the absorbed NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (17) becomes rich. When making the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (17) rich to release the NO.sub.x from the NO.sub.x absorbent (17), the degree of richness is made larger and the time the ratio is made rich is made shorter the higher the temperature of the NO.sub.x absorbent (17).

摘要： An exhaust gas purification system for an internal combustion engine includes a dual passage portion having a first passage and a second passage which are connected in parallel to each other. In the first passage, a first catalyst constructed of lean NOx catalyst is located and further a second catalyst constructed of oxidizing catalyst or three-way catalyst is located downstream of the first catalyst. In the second passage, a third catalyst constructed of oxidizing or three-way catalyst is located. A flow switching valve is provided so as to switch the flow of exhaust gas between the first passage and the second passage. The flow switching valve is switched so that exhaust gas flows through the third catalyst when the engine is being warmed-up and flows through the first catalyst and the second catalyst after the engine has been warmed-up.
