Description
方法に関する課題は、本発明によれば、入口面と、出口面と、入口面と出口面との間における流体が貫流できるハニカム構造物とを備え、このハニカム構造物が流体内の少なくとも1つの成分に対する蓄積手段を有しているハニカム体内での流体の処理方法において、流体内の蓄積すべき成分の濃度が、ハニカム構造物内で出口面から最小距離を隔てて検出され、その最小距離は、成分の設定最高濃度の超過時に、ハニカム構造物の横断面のいずれの個所での該最高濃度が出口面に到達することなしに、蓄積手段の再生処置が有効となるまで、ハニカム構造物内において蓄積すべき成分の濃度を検出する位置と出口面との間の蓄積容積がその成分をさらに蓄積するのに十分であるように設定されていることによって解決される。
本発明の有利な実施態様はそれぞれ従属請求項に記載されている。
図1は本発明に基づくハニカム体の概略構成図、
図2は本発明に基づくハニカム体の正面図、
図3は排気装置と本発明に基づくハニカム体とを備えた内燃機関を示す。
含まれているほぼすべてのNOxは直ぐに蓄積される。ガス流5の流れ方向において蓄積手段が徐々にNOxを充填され、これによって、入口面3の方向から出口面4の方向に移動する濃度前面が形成される。この前面は平面ではなく、むしろ通常は湾曲されているかギザギザが入っている。その濃度前面が測定センサ6に到達したとき、確かに測定センサ6が最高濃度を検出するが、ハニカム体内には、その最高濃度が入口面3にかなり近くに位置するかあるいは測定センサ6の位置より出口面4の近くに位置する個所が存在する。従って、測定センサ6と出口面4との最小距離7は、通常の運転条件下でNOxの通り抜けが生じないように選択されている。即ち、ハニカム構造物2の出口面4からNOxが流出しないようにされている。
