Exhaust gas purifying apparatus |
摘要 |
An oxidation catalyst apparatus and a particulate collecting filter are provided sequentially from an upstream side in an exhaust gas passage of a diesel engine. A ratio of the weight of Pd to a sum of the weights of Pt and Pd carried on the oxidation catalyst apparatus is satisfactory with the following inequality: 0.05<=Pd/(Pt+Pd)<=0.75. When the rise of the temperature of the particulate collecting filter is needed, fuel is supplied into the oxidation catalyst apparatus.
