Description
− 排出ガスを中に流すように意図された混合ダクトと、
− 混合ダクトの上流端部の中心において、混合ダクト内に液体媒体を注入するための注入手段と、
− 混合ダクトの上流に配置された吸入ダクトであって、吸入ダクトは、排出ガスを受け入れるための吸入口を上流端部に有し、混合ダクトに排出ガスを送達するために、混合ダクトの上流端部への排出口を下流端部に有する、吸入ダクトと
を備える。この吸入ダクトは、第1のダクト・セクションと、第2のダクト・セクションとを備え、第1のダクト・セクションは、環状断面を有し、環状排出口をその下流端部に有しており、第2のダクト・セクションは、環状断面を有し、第1のダクト・セクションの下流に配置され、混合ダクトを囲んでいる。第2のダクト・セクションは、その下流端部を介して吸入ダクトの排出口に連結され、その上流端部に環状吸入口を有する。第1のダクト・セクションは、第2のダクト・セクションを囲む。吸入ダクトは、流れ反転セクションをさらに備え、流れ反転セクションは、第1のダクト・セクションの環状排出口を第2のダクト・セクションの環状吸入口に連結するためのものであり、吸入ダクトを通って流れる排出ガスの流れ方向を反転させるように構成され、これにより、吸入ダクトを通って流れる排出ガスは、第1のダクト・セクション内の排出ガスの流れ方向とは逆の方向において第2のダクト・セクションを通って流される。
