Description
本発明の一実施形態に係る排気処理装置1を図1および図2に示す。図1は排気処理装置1の側面図であり、図2は排気処理装置1の側面断面図である。この排気処理装置1は、ディーゼルエンジン等の内燃機関から排出される排気ガスを浄化するディーゼル・パーティキュレート・フィルター装置である。排気処理装置1は、入口ユニット2と、処理ユニット3と、出口ユニット4とを備える。
入口ユニット2は、処理ユニット3に対して排気ガスの流れの上流側に配置されており、内燃機関の排気通路(図示せず)に接続される。入口ユニット2は、第1本体管部5と、入口管部6とを有している。
処理ユニット3は、排気処理装置1に送られた排気ガスを浄化するためのユニットである。処理ユニット3は、図2に示すように、第2本体管部31と、フィルター33とを有する。
以下、排気処理装置1の製造手順のうち、特に、入口ユニット2の製造手順について図3に基づいて説明する。
この排気処理装置1では、入口管部6の第1部品23が第1本体管部5の開口を閉塞する部材を兼ねている。このため、部品点数を削減することができ、組み立てを容易に行うことができる。
上記の実施形態では、管状部分51は、軸方向に沿ったストレート形状を有しているが、管状部分51の形状はこれに限られない。例えば、管状部分51が本体管部側ほど幅広な形状であってもよい。この場合、排気ガスを入口管部6から第1本体管部5へと流れ易くすることができる。
