ABSTRACT:
A noble metal base catalyst for decomposing a portion of NOx included in engine exhaust gas into intermediate products such as N.sub.2 O and NO.sub.2 is installed in an exhaust conduit of a lean burn engine. Further, an intermediate product decomposing means for decomposing the intermediate products produced by the noble metal base catalyst into N.sub.2 and O.sub.2 is installed downstream of the noble metal base catalyst. The noble metal base catalyst has a high thermal durability, and the noble metal base catalyst and the intermediate product decomposing means decompose NOx into N.sub.2 and O.sub.2 without a large amount of HC.
