Description
本願は、2010年2月10日に出願された米国仮特許出願第61/303,146号の利益を主張する、2011年2月9日に出願された米国特許出願第13/023,870号の一部継続出願である、2011年6月21日に出願された米国特許出願第13/164,976号に対する優先権を主張する。上記各出願の開示内容の全体が参照により本明細書に援用される。
本開示は、インジェクタシステムに関し、より詳細には、ディーゼルエンジン排気ガスからの窒素酸化物(NOx)排出量を低減するために尿素水溶液等の試薬(試薬)を排気ガス流に噴射するインジェクタシステムに関する。
本項目は、本開示に関連する背景技術情報を提示するが、それらの背景技術情報は必ずしも従来技術ではない。リーンバーンエンジンは、過剰な酸素、すなわち利用可能な燃料の完全燃焼に必要な量よりも多くの酸素を用いて動作することにより燃料効率を向上させる。そのようなエンジンは、「リーン」動作、すなわち「希薄混合気」による動作を行う。しかしながら、それによって得られる、非リーンバーン燃焼とは対照的な燃料節約の向上あるいは増大は、望ましくない汚染排出物質、具体的には窒素酸化物(NOx)の形態の汚染排出物質によって相殺される。
本項目は本開示の概要を提示するものであり、全ての範囲や全ての特徴を包括的に開示するものではない。
図1は、本教示によるインジェクタを用いた汚染排出量制御システムを備える例示的なオンロード用ディーゼルエンジンの概略図である。
ここで、例示的な実施形態を添付の図1〜図48を参照しながらより詳細に説明する。本教示は、ディーゼルエンジンとNOx排出量の低減とに関して記載するが、これに限定されるものではなく、例えば、ディーゼル、ガソリン、タービン、燃料電池、ジェット、あるいは排気流を排出する任意の他の動力源などから排出される排気ガス流に関して用いることができる。さらに、本教示は、複数の望ましくない排出物質のいずれか1つの低減に関して用いることができる。更なる説明については、「霧状流体を噴射する方法及び装置」という名称で2008年11月21日に出願された、本発明の譲受人に譲渡された米国特許出願第12/275,539号を参照されたい。この米国特許出願は参照により本明細書に援用される。したがって、本発明は、エンジン排気ガスからの排出量を低減するために、尿素水溶液等の試薬を排気ガス流中に噴射する改善された方法及び装置構造を提供する。さらに、本教示は、従来技術の尿素水インジェクタに対する改善、特に、重要な構成部品の放熱の改善と、試薬インジェクタのサイズ及び複雑性の低減と、動作及び機能の改善とを含む、尿素水インジェクタに対する改善を提供する。
、約60psi〜80psiの比較的低い圧力、又は幾つかの実施形態では約60psi〜150psiの圧力)に維持するように圧力調整器(図示せず)を設けてもよく、前記圧力調整器は試薬インジェクタ100からの戻りライン35内に配置してもよい。試薬インジェクタ100につながる可撓性の供給ライン24内に圧力センサを設けてもよい。本システムに、凍結した尿素を解凍するため、又は尿素が凍結することを防止するために、種々の凍結防止対策を組み込んでもよい。例えば、システムの動作中、インジェクタが試薬をエンジン排気管内の排気ガス中等に放出しているかどうかにかかわらず、試薬は、インジェクタを冷却するために試薬タンク12と試薬インジェクタ100との間を(すなわち、試薬タンク12から試薬インジェクタ100へ、試薬インジェクタ100から試薬タンク12へ)連続的に循環させられる。また、試薬を低温のまま維持するためにインジェクタ内での当該試薬の滞留時間は最小限にされる。
れているように、流路316は、試薬がばね136の中央部分及び中央穴部134に流れるように導く。より詳細には,幾つかの実施形態では、効率的な冷却及び流体の流れの改善のため、ピントルヘッド132は、ばね136の中央へ試薬を送出するように、中央穴部134と同軸である部屋141を含む形状を有する。
