Abstract
少なくとも1つの酸化触媒(4)に、内燃機関(2)の排ガス流(32)に還元剤(61)を供給するための供給装置(6)が組み込まれている。
更に本発明は、内燃機関(2)の排ガスを浄化するための、対応する方法に関する。
Description
特にディーゼルエンジン及びガソリン直接噴射装置を備えた内燃機関によって放出されるような、酸素の豊富な排ガス中の窒素酸化物成分を減少させるためには、還元剤を排ガス路に導入することが公知である。還元剤としては、例えばガスとして排ガス流内にもたらすことのできるNH3が適している。このいわゆる選択還元触媒(SCR,“selective catalytic reduction”)では、アンモニアが排ガス中に含まれる窒素酸化物と相俟って選択的に窒素分子及び水に変換される。但し、純粋なアンモニアガスは、その有毒性に基づいて自動車における使用には適していない。公知の方法では、還元剤として尿素水溶液が使用される。この場合、尿素の加熱分解と、触媒を用いた引き続く加水分解とによって初めて、本来の還元剤であるアンモニアが遊離される。
内燃機関の排ガスを浄化するための排ガス浄化装置では、内燃機関の排ガス通路内に配置された少なくとも1つの酸化触媒及びこの酸化触媒の下流側に配置された少なくとも1つの選択還元触媒装置(SCR触媒)が設けられている。本発明では、少なくとも1つの酸化触媒に組み込まれた、内燃機関の排ガス流に還元剤を供給するための供給装置が設けられている。本発明による排ガス浄化装置を用いて、特にディーゼルエンジン若しくは燃料直接噴射装置を備えたガソリンエンジンの比較的酸素の豊富な排ガスから、窒素酸化物(NOx)を効果的に除去することができる。本発明により、排ガス浄化システムの構成長さを著しく減少させることが可能であり、この場合、同時に排ガス流内での還元剤の良好な変換が保証されている。SCR触媒において還元剤を良好に分散させるために一般に必要な約40cmの混合区間は、システム内に不都合な圧力低下が発生すること無しに著しく減少され得る。SCR触媒は、一般に必要な長い混合区間の省略に基づいて必ずしも車両のアンダボデー領域に組み込まれる必要はなく、場合によっては内燃機関の排ガス出口付近へ移動可能である。このようにして、有利には浄化作用に影響を及ぼす、排ガス浄化装置内のより好適な温度特性が得られる。
NO+1/2O2→NO2
SCR触媒には、場合によっては尿素分解触媒(“H”)が前置されていてもよく、この尿素分解触媒では以下の反応が進行する:
(NH2)2CO+H2O→2NH3+CO2
SCR触媒(“R”)自体においては、次の選択還元触媒反応が行われる:
2NH3+NO+NO2→2N2+3H2O
SCR触媒には選択的に別の酸化触媒(“O”)が後置されていてよく、この別の酸化触媒では次の反応が行われる:
2NH3+3/2O2→N2+3H2O
