ABSTRACT:
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.
