Description
された粒子と接触し、後者を(たとえば二酸化炭素に)変換する。しかしながら、煤または粒子の酸化がこのように同時にもたらされると、二酸化窒素が減り、一酸化窒素が増えることとなる。しかしながら、このように、利用可能な二酸化窒素が速やかに使い果たされてしまい、さらなる変換のために利用できる二酸化窒素がなくなってしまうこととなる。したがって、ここでは、既に使用された一酸化窒素を再び酸化して二酸化窒素を形成することにより、下流に位置するチャネルの部分的な領域における粒子の変換のために二酸化窒素を再び利用できるようにする装置が特定される。
説明の主題に含まれる。
示す。このために、(必要に応じて、複数繰返して配置され、積み重ねられている)2つの異なる構成要素を用いてチャネル5を形成する。図3の上方部分には波形の金属箔11が示される。ここでは、この波形によりチャネル5の設計が決定的に定められる。当該波形に加えて、金属箔11は異なる突起22および開口部23を有する。1つの部分的な排気ガスの流れについての流れの方向10が一例として示される。排気ガスの流れが初めに当たる突起22に関して、当該排気ガスの流れの一部が、上向きに、特に隣接して配置されたフィルタ層13に向かって逸らされる。しかしながら、別の部分的なガスの流れが突起22を流れ過ぎてチャネル5に留まる。次いで、この部分的なガスの流れが、逆に形成された種類の突起22に当たり、これにより、たとえばチャネル5内の圧力条件が異なっていることで排気ガスの流れの新たな分割が可能となる。これにより、排気ガスの一部が、隣接するチャネル5における開口部23を通過し、排気ガスの残りの部分がチャネル5に沿ってさらに流れる。
および第2の部分的な領域15は、ここでも予め規定可能な長さ9を有する1つの支持構造3内に配置される。しかしながら、基本的には第2の部分的な領域15と第1の部分的な領域14との間に隙間を設けることも可能であり、ここでは、2つの支持構造、または1つのコンバータおよび1つの支持構造が好ましくは設けられている。
