摘要： An exhaust purifying apparatus purifies an unburnt gas component, such as unburnt hydrocarbon (HC), discharged from an internal combustion engine without fail and prevents the unburnt hydrocarbon from being discharged into the atmosphere. In order to achieve this, the exhaust gas purifying apparatus is provided with a plurality of exhaust passages connected to the internal combustion engine. A joint exhaust passage is formed by merging the exhaust passages and an exhaust gas flows through the joint exhaust passage. An adsorption/desorption unit is provided in each of the exhaust passages for adsorbing an unburnt gas component contained in the exhaust gas that flows through each of the exhaust passages at a temperature lower than a predetermined temperature. The adsorption/desorption unit desorbs the adsorbed unburnt gas component at a temperature equal to or higher than the predetermined temperature. A desorption/adjustment mechanism synchronizes timing of the unburnt gas component desorbed from the adsorption/desorption units into the exhaust purifying units.

摘要： A device for purifying exhaust gas includes an HC adsorbent and an exhaust gas purifying catalyst disposed in an exhaust gas passage in this order from the upstream side. The exhaust gas purifying catalyst is provided with an O.sub.2 storage capability, i.e., the exhaust gas purifying catalyst is capable of absorbing oxygen in the exhaust gas when the air-fuel ratio of the exhaust gas is lean, and is capable of releasing the absorbed oxygen when the air-fuel ratio of the exhaust gas becomes rich. When the engine starts, the HC adsorbent adsorbs HC in the exhaust gas. When the temperature of the exhaust gas becomes high, the HC adsorbent releases the adsorbed HC. The device also includes an engine control unit which operates the engine at a lean air-fuel ratio during a predetermined period before the releasing of the HC from the HC adsorbent occurs. Therefore, oxygen is absorbed and stored in the exhaust gas purifying catalyst before the releasing of HC occurs. When the releasing of HC from the HC adsorbent occurs, the air-fuel ratio of the exhaust gas flowing into the exhaust gas purifying catalyst becomes rich due to the HC released from the HC adsorbent. This causes the exhaust gas purifying catalyst to release the absorbed oxygen, and the HC in the exhaust gas is purified by the exhaust gas purifying catalyst using the released oxygen.
摘要翻译：废气净化装置包括从上游侧依次排列在废气通道内的HC吸附剂和排气净化催化剂。废气净化催化剂具有O 2储存能力，即，当废气的空燃比稀的时，废气净化催化剂能够吸收废气中的氧，并且能够释放吸收的氧当排气的空燃比变浓时，当发动机启动时，HC吸附剂吸附废气中的HC。当废气的温度变高时，HC吸附剂释放吸附的HC。该装置还包括发动机控制单元，其在从HC吸附剂释放HC之前的预定时间段内以稀空燃比操作发动机。因此，在HC释放出现之前，氧气被吸收并储存在排气净化催化剂中。当从HC吸附剂中释放出HC时，流入废气净化催化剂的排气的空燃比由于从HC吸附剂释放的HC而变浓。这使得废气净化催化剂释放吸收的氧，并且通过使用释放的氧气的废气净化催化剂净化废气中的HC。

摘要： A device for purifying the exhaust gas of an engine having a plurality of cylinders divided into first and second cylinder groups, the first and the second cylinder groups being connected to first and second exhaust passage, respectively, and performing a lean operation, comprises an NH.sub.3 synthesizing catalyst arranged in the first exhaust passage, and an exhaust gas purifying catalyst arranged in an interconnecting passage, which interconnects the first passage downstream of the NH.sub.3 synthesizing catalyst and the second exhaust passage, for purifying the inflowing NO.sub.X and NH.sub.3. An additional engine performing a rich operation is provided and the exhaust gas thereof is fed to the first exhaust gas passage upstream of the NH.sub.3 synthesizing catalyst to make the exhaust gas air-fuel ratio of the exhaust gas flowing into the NH.sub.3 synthesizing catalyst rich, to thereby synthesize NH.sub.3 therein. An amount of NH.sub.3 or NO.sub.X flowing into the exhaust gas purifying catalyst is obtained, and the additional engine is controlled in accordance with the obtained NH.sub.3 or NO.sub.X amount to control the amount of the reducing agent flowing to the exhaust gas purifying catalyst.

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.
