摘要： An engine (1) has first and second cylinder groups (1a and 1b). The first cylinder group (1a) is connected to a three way (TW) catalyst (8a). The second group (1b) and the TW catalyst (8a) are connected, via an interconnecting duct (13) to an NH3 adsorbing and oxidizing (NH3-AO) catalyst (14a). The first group (1a) performs the rich operation, and the second group (1b) performs the lean operation. In the TW catalyst (8a), NOx exhausted from the first group (1a) is converted to NH3, and the NH3 reduces the NOx exhausted from the second group (1b) in the NH3-AO catalyst (14a). An NOx occluding and reducing (NOx-OR) catalyst (11a) is arranged in the exhaust passage between the second group (1b) and the interconnecting duct (13), to thereby suppress the NOx amount flowing into the NH3-AO catalyst (14a).

摘要： A three-way catalyst (8a) is connected to a first group of cylinders (1a) whereby exhaust gas discharged from the first group of cylinders (1a) and passing through the three-way catalyst (8a) and exhaust gas discharged from a second group of cylinders (1b) are conducted to an exhaust gas purifying catalyst (14). The second group of cylinders (1b) are operated with a lean gas. The first group of cylinders (1a) are operated with a rich gas, so that NH3 is generated from NOx in the exhaust gas of the first group of cylinders (1a) by means of the three-way catalyst (8a). The exhaust gas purifying catalyst (14) causes NH3 from the three-way catalyst (8a) to purify NOx in the exhaust gas of the second group of cylinders (1b). An amount of HC flowing into the three-way catalyst (8a) is found, and when the amount of HC exceeds a set amount, the first group of cylinders (1a) is temporarily operated with a lean gas, thereby maintaining a favorable catalytic activity of the three-way catalyst (8a).

摘要： To accomplish an optimum regeneration operation of an exhaust emission control apparatus (124), the quantity of nitrogen oxide (C) absorbed in catalysts (125, 812) and an exhaust gas temperature (T) are predicted on the basis of future driving condition information obtained from a car navigation system (141, 841), etc., and an appropriate time for regeneration is determined at which the absorption quantity of the catalysts (125, 812) is expected to be large and the exhaust gas temperature (T) is expected to be in a predetermined temperature range. When the time for regeneration is reached, the exhaust gas is made rich and the nitrogen oxides are emitted from the catalyst (125, 812) to regenerate the catalyst. The nitrogen oxides emitted from the catalyst (125, 812) are reduced to innoxious substances by unburnt hydrocarbons in the exhaust gas, etc. When this apparatus is applied to a particulate filter (814) of a diesel engine, the chance of operation for raising the exhaust gas temperature (T) decreases, so that deterioration of the fuel cost can be restricted.

摘要： A moisture adsorbent (32) for adsorbing moisture in exhaust gas and an NOx adsorbent (34) for adsorbing NOx are disposed in a bypass passage (30) for bypassing an exhaust passage (16) of an internal combustion engine (10). When an adsorption operation to the NOx adsorbent (34) is executed, inflow of the exhaust gas to the bypass passage (30) is allowed until the moisture amount that flows into the water adsorbent (32) reaches an allowable moisture inflow amount. The allowable moisture inflow amount is determined based on a residual moisture amount before the starting of the adsorption operation in the moisture adsorbent (32). The residual moisture amount in the water adsorbent (32) can be determined based on the temperature of the moisture adsorbent (32) at the immediately preceding execution of the purge operation.

摘要： An exhaust manifold (7) of an engine (1) is connected to a three way (TW) catalyst (8a), and the TW catalyst (8a) is connected to an NH3 adsorbing and oxidizing (NH3-AO) catalyst (10a). The engine (1) performs the lean and the rich engine operations alternately and repeatedly. When the engine (1) performs the rich operation and thereby the exhaust gas air-fuel ratio of the exhaust gas flowing into the TW catalyst (8a) is made rich, NOx in the inflowing exhaust gas is converted to NH3 in the TW catalyst (8a). The NH3 is then adsorbed in the NH3-AO catalyst (10a). Next, when the engine (1) performs the lean operation and thereby the exhaust gas air-fuel ratio of the exhaust gas flowing into the TW catalyst (8a) is made lean, NOx in the exhausted gas passes through the TW catalyst (8a), and flows into the NH3-AO catalyst (10a). At this time, NH3 adsorbed in the catalyst (10a) is desorbed therefrom, and reduces the inflowing NOx.
