Description
図1はマニバータおよびその周辺を含む排気系の一部を車両の後方から見た図である。図2は図1におけるII矢視図(上方から見た図)である。図3は図1におけるIII矢視図(車両の右側から見た図)である。
マニホールド接続配管1は、ステンレス製であって、図示しない排気マニホールドと第一マニバータ2とを連結する配管である。このマニホールド接続配管1は、排気ガス流れ方向の上流部分が略水平方向(車幅方向)に延び、排気ガス流れ方向の下流部分が略鉛直方向(より具体的には、鉛直方向に対して所定の傾斜角度(例えば15°程度)だけ傾斜する方向)に延びるように湾曲されている。
第一マニバータ2は、略円筒形状の第一排気管21と、この第一排気管21の内部に収容されたNSR触媒(図1における破線を参照)22とを備えている。
本実施形態の特徴とする部材である連結部材3について説明する前に前記第二マニバータ4について説明する。
次に、連結部材3について説明する。
次に、エンジンの運転時における排気ガスの流れについて説明する。
以上説明した実施形態は、連結部材3をステンレスのロストワックス鋳造により成形した場合について説明した。連結部材3の材質および製法はこれに限定されるものではなく、適宜選択可能である。
22 NSR触媒(第一の排気浄化装置)
3 連結部材
33 底板部
34 開口
35 溝
42 NSR触媒(第二の排気浄化装置)
44 第二排気管
Claims (3)
- 第一の方向に沿って延びる第一排気管と、
この第一排気管よりも排気ガス流れ方向の下流側に位置し且つ前記第一の方向に対して交差する第二の方向に沿って延びる第二排気管と、
前記第一排気管と前記第二排気管とが前記第一の方向から見て重なるように、これら排気管同士を連結する連結部材と、
を備え、
前記連結部材は、前記第一排気管の内部と前記第二排気管の内部とを連通させる開口と、前記第一の方向から見て前記開口に隣接し且つ前記第一排気管と前記第二排気管とが前記第一の方向から見て重なる領域に対応して形成された底板部とを備えており、この底板部において前記第一排気管の内部側に向いている面には、この底板部の外縁部に沿って前記開口に向かって延びる溝が形成されていることを特徴とする排気管の構造。 - 請求項1記載の排気管の構造において、
前記第一排気管の内部には第一の排気浄化装置が配設されている一方、
前記第一の方向から見て前記第一排気管と前記第二排気管とが重なる領域における前記第二排気管の内部には第二の排気浄化装置が位置していることを特徴とする排気管の構造。 - 請求項1または2記載の排気管の構造において、
前記連結部材は、ステンレスのロストワックス鋳造により成形されていることを特徴とする排気管の構造。
