Abstract

　本発明の課題は、選択還元型触媒６等の後処理装置に対し排気ガス３を反転させて導入しても、後処理装置に対し排気ガス３の流れ分布を均一化して導入し得るようにすることにある。排気ガス３を通過させて浄化する選択還元型触媒６（後処理装置）を排気系に備え、この選択還元型触媒６に対し排気ガス３を反転させて導入するレイアウトが採用された排気浄化装置に関し、選択還元型触媒６の入側端面を被包し且つ該選択還元型触媒６の軸心方向と略直交する向きから排気導入口１３を介して排気ガス３を導き入れる導入部１４を備え、選択還元型触媒６の入側端面に対し離間する方向へ反り且つ排気導入口１３から排気ガス３の導入方向へ離れるに従い選択還元型触媒６の入側端面に近接する窪み部１５（第一の窪み部）を前記導入部１４に形成する。
