Abstract

　レイアウトの制約が少なく、省スペース化を実現可能な排気浄化装置を提案する。本発明に係る排気浄化装置は、酸化触媒及びＰＭ捕集フィルタを収納した筒形の第１の筐体１０と、還元触媒及びアンモニア酸化触媒を収納した筒形の第２の筐体２０と、を互いの軸線１０ａ，２０ａがほぼ平行となるようにして近接配置すると共に、これら両筐体の遠端部どうしを連結する連通管３０を、該連通管の軸線３０ａが筐体の軸線１０ａ，２０ａとほぼ平行となるように配管してある。そして、第１の筐体１０から第２の筐体２０へ至る排気の流路が連通管３０により折り返され、排気中に液体還元剤を噴射するノズル３１が連通管３０に配設されている。
