Claims (6)
- 内燃機関の複数の排気ポートに連通接続され排気ガス浄化装置を内蔵する内燃機関の排気集合装置において、前記排気ガス浄化装置を収容する筒体と、該筒体を囲繞するように形成される容器であって、前記筒体の外面との間に前記複数の排気ポートに連通接続される複数の排気流路が形成されると共に、該複数の排気流路が前記筒体の一方の開口端に連通するように形成された容器と、前記筒体の他方の開口端に連通接続される排出管とを備え、前記複数の排気流路は、前記筒体の軸に対し直交する方向に前記容器が環状に膨出形成されて成る複数の環状流路を有し、該複数の環状流路が前記筒体に並設されていることを特徴とする内燃機関の排気集合装置。
- 前記容器は、前記複数の環状流路内の排気ガスを前記筒体の一方の開口端に案内する案内部を有することを特徴とする請求項1記載の内燃機関の排気集合装置。
- 前記容器は、前記内燃機関のクランク軸に対し前記筒体の軸が平行となるように配置されることを特徴とする請求項1又は2記載の内燃機関の排気集合装置。
- 前記複数の排気流路は、前記複数の環状流路と前記複数の排気ポートとを連通接続する複数の分岐管を有することを特徴とする請求項1乃至3の何れか一項に記載の内燃機関の排気集合装置。
- 前記複数の分岐管は、前記内燃機関のクランク軸に対し直交する方向に並設されていることを特徴とする請求項4記載の内燃機関の排気集合装置。
- 前記筒体は、前記排気ガス浄化装置の下流側で、排気音を低減する消音装置、排気ガスの熱を回収し車室内の暖房に供する排気熱回収装置、及び、排気ガスの熱エネルギを直接電気エネルギに変換する熱電型発電装置の少なくとも一つの装置に連通接続されることを特徴とする請求項1乃至5の何れか一項に記載の内燃機関の排気集合装置。
