摘要： In an exhaust purification apparatus of an internal combustion engine having an NOx absorption and release material in an exhaust conduit, a heater is provided close to the NOx absorption and release material. When an NOx absorption operation continues for a predetermined period, the heater is switched on to raise the temperature of the NOx absorption and release material above a predetermined temperature, for example, 500.degree. C. When the temperature of the NOx absorption and release material is high, the NOx absorption and release material releases absorbed NOx and is regenerated.

摘要： An NO.sub.x absorbent (18) is disposed in an exhaust passage of an internal combustion engine and the exhaust gas is constantly made to circulate through the NO.sub.x absorbent (18) during the operation of the engine. The NO.sub.x absorbent (18) absorbs the NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (18) 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 (18) becomes the stoichiometric air-fuel ratio or rich. In the majority of the engine operation region, the lean air-fuel mixture is burned in the combustion chamber (3), and the NO.sub.x generated at this time is absorbed into the NO.sub.x absorbent (18). The air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (18) is periodically made the stoichiometric air-fuel ratio or rich, and the NO.sub.x absorbed in the NO.sub.x absorbent (18) is released, and simultaneously reduced.

The NO.sub.x absorbent (19) absorbs the NO.sub.x when the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (19) 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 (19) becomes the stoichiometric air-fuel ratio or rich. When the lean air-fuel mixture is burned, if the temperature of the NO.sub.x absorbent (19) is low, the NO.sub.x oxidized by the NO.sub.x oxidizing agent (18) is absorbed by the NO.sub.x absorbent (19), while if the temperature of the NO.sub.x absorbent (19) is high, the NO.sub.x is oxidized by the NO.sub.x absorbent (19) and absorbed in the NO.sub.x absorbent (19).

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. It estimates the amount of NO.sub.x absorbed in the NO.sub.x absorbent (17) from the engine load and the engine rotational speed and when the amount of the estimated NO.sub.x becomes the maximum NO.sub.x absorption capacity of the NO.sub.x absorbent (17), makes the air-fuel ratio of the exhaust gas flowing into the NO.sub.x absorbent (17) rich.

摘要： A device for purifying the exhaust gas of an engine comprises a NO.sub.X absorbent arranged in the exhaust passage. The NO.sub.X absorbent absorbs NO.sub.X therein when the air-fuel ratio of the inflowing exhaust gas is lean, and releases the absorbed NO.sub.X therefrom when the oxygen concentration in the inflowing exhaust gas becomes lower. The NO.sub.X absorbent also absorbs SO.sub.X therein when the air-fuel ratio of the inflowing exhaust gas is lean, and releases the absorbed SO.sub.X therefrom when the oxygen concentration in the inflowing exhaust gas becomes lower, with the temperature of the NO.sub.X absorbent being higher than a SO.sub.X releasing temperature. The air-fuel ratio of the exhaust gas flowing to the NO.sub.X absorbent is made rich temporarily when the temperature of the NO.sub.X absorbent is higher than SO.sub.X releasing temperature and when the flow rate of the exhaust gas flowing through the NO.sub.X absorbent is lower than a predetermined flow rate, to release the absorbed SO.sub.X from the NO.sub.X absorbent.

摘要： A technique that, in an exhaust gas purification apparatus of an internal combustion engine, can avoid a decrease in a NOx purification rate by adding a reducing agent as continuously as possible, while avoiding NH3 from passing through a selective reduction type NOx catalyst to a downstream side thereof. The selective reduction type NOx catalyst has an active spot which purifies NOx by the use of NH3, and an adsorption site which adsorbs NH3, wherein a vicinity site, which is located in the vicinity of the active spot, and a distant site, which is located distant from the active spot, exist in the adsorption site. The addition of the reducing agent from the reducing agent addition part is controlled based on the desorption rate of NH3 in the vicinity site so as to continue to cause the NH3 adsorbed to the vicinity site to exist.

摘要： In an internal combustion engine, a pair of NOx storing catalysts are arranged in series in an engine exhaust passage. When causing the upstream NOx storing catalyst to release NOx and store the released NOx in the downstream NOx storing catalyst, the oxygen concentration in the exhaust gas is temporarily reduced in a state where the exhaust gas is maintained at a lean air-fuel ratio. As opposed to this, when releasing NOx from the upstream NOx storing catalyst and the downstream NOx storing catalyst and reducing the NOx, the air-fuel ratio of the exhaust gas is temporarily switched from lean to rich.
