Description
知器はラムダセンサである。
第1の検知器15が形成される。したがって、第1の検知器15は、第1の排ガス線路10内を流れる排ガスおよび第2の排ガス線路11内を流れる排ガスの両方と接触することになるため、ハニカム体1内の触媒変換前に複数の排ガス線路10,11内でただ1つの検知器15によって排ガスの特性値を決定することができる。
流出していなくてもNOX吸蔵材の再生ステップを開始させることができる。
第2の検知器、17 隔壁、18 最小間隔、19 第2の正面側表面。
Claims (5)
- 少なくとも2つの実質的に互いに分離された排ガス線路(10,11)と、排ガスについての少なくとも1つの特性値を測定するための少なくとも1つの検知器(15,16)とを備える排気システムにおいて、
少なくとも1つの検知器(15)が少なくとも2つの排ガス線路(10,11)と接触可能であり、
第1の正面側表面(7)と、第2の正面側表面(19)と、前記正面側表面間に延び少なくとも部分的に流体が貫流可能な空所(6)とを有する少なくとも1つのハニカム体(1)が、前記少なくとも2つの排ガス線路(10,11)内に形成され、
前記ハニカム体は、少なくとも2つのほぼ気密に互いに対して隔離された流れ領域(12,13)を有し、少なくとも1つの第1の流れ領域(12)が第1の排ガス線路(10)と接続されるとともに第2の流れ領域(13)が第2の排ガス線路(11)と接続され、前記排ガス線路(10,11)同士が第1の分離手段(9)によって分離されるとともに前記流れ領域(12,13)同士が第2の分離手段(14)によって分離され、
検知器(15,16)のための少なくとも1つの開口が前記第2の分離手段(14)の領域に形成されて、前記第1の流れ領域(12)内を流れる排ガスおよび前記第2の流れ領域(13)内を流れる排ガスの両方が、前記開口内に装入された検知器(15,16)と接触し、
前記少なくとも1つの検知器(15,16)は、流れ方向において前記少なくとも1つのハニカム体(1)より上流側で前記第1の分離手段(9)の中に形成されるか、または流れ方向において前記少なくとも1つのハニカム体(1)より下流側で前記第1の分離手段(9)の中に形成され、少なくとも1つの検知器(16)が前記第2の分離手段(14)の中に形成される、排気システム。 - 前記少なくとも1つの検知器(16)が、前記ハニカム体の前記第2の正面側表面(19)から指定可能な最小間隔(18)をあけて形成されることを特徴とする、請求項2に
記載の排気システム。 - 少なくとも1つの検知器(15,16)がラムダセンサであることを特徴とする、請求項1または2に記載の排気システム。
