Abstract
An exhaust purifying apparatus of an internal combustion engine is provided. The exhaust purifying apparatus includes a CO oxidation catalyst disposed in the exhaust flow passage of an internal combustion engine and capable of oxidizing and thereby purifying CO in the exhaust, and an HC adsorbent material loaded with a noble metal, for adsorbing HC in the exhaust. The exhaust purifying apparatus further includes an NOx adsorbent material for adsorbing NOx in the exhaust. These adsorbent materials are located on the upstream side in the exhaust flow direction with respect to the CO oxidation catalyst and disposed in order from the upstream. The CO oxidation catalyst contains Pd and CeOand is obtained by an oxidation treatment at a temperature of 850 to 950° C. The amount of Pd supported in the CO oxidation catalyst is from 0.1 to 2.5 mass % based on CeO.
