Abstract

　耐久性の低下を招くことなしに、小型化、コストダウンおよび浄化能力の向上を図ることができる排気浄化装置を提供する。エンジンＥからの排気ガスＧを導出する排気通路ＥＰに設けられ、触媒反応によって排気ガスＧを浄化するものであって、排気ガスＧの流れ方向Ｘに並んで複数の触媒ユニット４２，４３が配置され、各触媒ユニット４２，４３はハニカム構造体に触媒を担持させてなり、複数の触媒ユニットのうち少なくとも二つの触媒ユニット４２，４３では、下流側の触媒ユニット４３の方が上流側の触媒ユニット４２よりも、セル密度が高く、ハニカム構造体の容積が小さく、かつ主触媒となる元素の単位容積当たりの担持量が多い。
