Abstract
Description
本発明は、触媒後処理システム、詳細にはディーゼルエンジンなどの自動車用の触媒後処理システムに関する。より詳細には、本発明は、ディーゼル酸化触媒(DOC)と、ディーゼル酸化触媒(DOC)の下流に位置する再生可能な後処理装置とを組み込んだ触媒後処理システムに関する。本発明はさらに、後処理装置の能動的な熱処理中に、ディーゼル酸化触媒(DOC)の活性を維持する方法、および能動的な熱処理事象中に、ディーゼル酸化触媒(DOC)の消失を回避する方法に関する。
精巧なエンジン管理などの工学的設計と種々の触媒後処理装置とを組み合わせることにより、乗り物からの排気物の高まる規制は満たされてきた。
3種のDOCを同一のブリックを使用して調製し、それらの全ては、PGM総充填量が同一の40gft−3であった。各DOCは、直径が10.5インチ(266.7mm)であり、長さが4インチ(101.6mm)であった。全てのDOCを、オーブンにおいて12.5時間750℃で加熱することにより従来の老化に供したため、DOCは、使用されたDOCを代表するものであった。
各ディーゼル酸化触媒の熱分析は、2200rpmで稼働する、エンジン運転とエンリッチメントとの双方のためのEUV B7燃料(7%バイオ燃料)が供給されたディーゼルエンジンからの排気ガスを通すことにより行われた。エンジンは、DOCの上流の排気管に配置された第7の噴射器が装着された、2500rpmで235kWをもたらす7リットル容量EUVI6シリンダーエンジンであった。
結果を図1〜3に示すが、これらの図は、試験されたDOCの各々について温度を時間(秒)とプロットしたものである。
