前記ドージング本体に備えられたボス部材に装着されて、前記還元剤を前記ドージング本体内部に噴射するインジェクターと、
前記ドージング本体の内部に設置されて、前記流入部を通ってドージング本体に流入した排気ガスの流れを一定の経路にガイドするガイド部材と、を含み、
前記ガイド部材には、その面に複数の孔が形成され、
前記ドージング本体には、前記ガイド部材と結合して前記流入部を形成するバッフル部材が設置され、
前記バッフル部材は、前記ドージング本体に対して前記流入部を除く部分を覆うプレート形状でなり、
前記バッフル部材は、一端部が前記ドージング本体の端部より内側に入り込んだ傾斜に配置されて前記流入部を形成することを特徴とする。
車両の排気ガス後処理システム用ドージングモジュールは、多様に異なる形態で実施できるものであり、ここに挙げた実施形態に限定されるものではない。
以下の説明では、明細書全体にわたって同一または類似した構成要素については同じ符号を付け、説明に不必要な部分は省略していることを予め断っておく。また、図面では、部分的にある領域を拡大して示すなど、各構成部分の大きさ、厚さなど説明の便宜のために任意の大きさで示している。
図面を参照すると、ドージングモジュール100は、ドージング本体10、インジェクター30、ガイド部材50、バッフル部材70を主要構成部としており、以下にこれらの構成部をそれぞれ説明する。
インジェクター30は、排気系統に装着される2次噴射装置であって公知であるので、本明細書では、その構成に対するより詳細な説明は省略する。
一方、連結部13側の空間は、バッフル部材70とガイド部材50、さらにドージング本体10の閉鎖面と内壁面で囲まれており、流動通路71を通った排気ガスは、旋回流となって連結部13に向う流れになる。
