Claims (2)
- 吸気管の途中にベンチュリ部を形成して該ベンチュリ部の外周に環状チャンバを設けると共に、該環状チャンバに対し排気側から排気ガスの一部を抜き出して導くEGRパイプを接続し、前記ベンチュリ部に環状チャンバ内部と吸気管内部とを連通する環状スリットを形成して前記ベンチュリ部を上流側の縮径部と下流側の拡張部とに分割したEGRガス混合装置であって、前記環状スリットが前記ベンチュリ部の軸心方向に間隔を空けて形成されていると共に、前記環状チャンバに前記EGRパイプを接続するにあたり、該EGRパイプの軸心が前記環状スリットの中間位置より縮径部側へオフセットされ且つ前記EGRパイプを延長した先が環状スリットに対し部分的に重複するように配置されており、しかも、ベンチュリ部の縮径部の終端に対し拡張部の始端を半径方向外側にずらして段差が形成されるようにしたことを特徴とするEGRガス混合装置。
- 環状スリットの最下レベルより低い環状チャンバの領域を前記環状スリットの最下レベルまで底上げして形成したことを特徴とする請求項1に記載のEGRガス混合装置。
