    摘要： A fuel vapor adsorbing device (10, 60, 70, 70′, 80) for adsorbing residual fuel vapors that remain in an intake conduit (1, 2, 3, 4) of an induction system of an internal combustion engine when the internal combustion engine is stopped may include an adsorbing member (40, 40′) that is constructed to adsorb the residual fuel vapors and is disposed along an inner wall surface of the intake conduit. The adsorbing member is arranged and constructed to form a supplemental intake path (T, T′, T′″) between the adsorbing member and the inner wall surface of the intake conduit, so that intake air of the engine can flow through the supplemental intake path.

    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： 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.
