Description
本願は、2013年8月26日に提出された米国仮出願連続番号61/869,859、および2014年8月26日に提出された米国実用新案出願連続番号14/468,858の恩恵を主張し、それらの全体をここに引用により援用する。
1.技術分野
本発明は、一般に、保温熱シールドに関し、とりわけ、巻付け可能な多層の保温熱シールドに関する。
車両排気に対する基準は、酸化窒素および一酸化炭素の排出を低減することにおいて、ますます厳しくなってきている。これらのガスの排出を低減することを促進するために、多くの車両適用例は、たとえば、選択的触媒還元(SCR)適用例を含む。SCR適用例は、典型的には、アンモニアまたは尿素溶液を触媒コンバータの上流の排気管に注入するための導管を組込む。注入された溶液は蒸発して排気ガスと混合することにより化学反応を引き起こし、それは、酸化窒素および一酸化炭素排出を低減し、その代わりに窒素と水とを発生させる。しかしながら、SCR適用例を効率よく実行するためには、注入された溶液と混合する排気ガスが最高の高温に留まることを必要とし、そうでない場合には、意図される酸化窒素ガスおよび一酸化炭素ガスの化学変換が逆方向に影響を受け、非効率的となり、それによって、望ましくないその排出をもたらす結果となる。したがって、排気ガスを、排気システムに沿って上流に、かつSCRシステム内において最高温度に維持することは、望ましく、かつ重要である。
この発明の1つの態様に従うと、可撓性のある巻付け可能な多層化された熱シールドが提供される。熱シールドは、反射性の最外層と、高温糸からなる最内層と、最外層と最内層との間に挟まれる不織材料からなる中間層とを含む。そのようなものとして、熱シールドは、各層が意図されるように別々に機能すること、およびさらにはともに機能して、熱シールドが全体として意図されるように機能することを可能にする相乗効果を与えることを可能にする態様で互いを保護する少なくとも3つの異なる層からなる。
本発明のこれらならびに他の態様、特徴および利点は、現在好ましい実施例および最善の形態の、以下の詳細な記載、特許請求の範囲ならびに添付の図面との関連において考慮されると、より容易に理解されることになる。
図面をより詳細に参照して、図1は、例示的に、かつ限定なく、熱的および他の環境影響に対する望ましいシールドを、概ね12で表現される排気システムのシールドされる部分などに与える、この発明の1つの態様に従って構築される、以下において熱シールド10と称される、巻付け可能な可撓性のある多層化された熱シールドを示す。熱シールド10は、排気システム12内の高温排気ガスの外部周囲環境Eへの放射を防ぎ、したがって高温排気ガスの熱的損失を防ぐこと;排気システム上における外部の対流を含む、外部周囲環境Eにおける熱的影響が、排気システム内における高温排気ガスの温度の低下を防ぐこと、およびさらには、流体などのような外部環境要素が排気システム12のシールドされる部分内における温度排気ガスに影響を与えるかまたはそうでなければそれに達してその低下を防ぐことを含むが、それらに限定されない、複数のシールディングの恩恵を与える。そのようなものとして、排気システム12からの熱的損失に対する所望のシールディングを与えることによって、排気システム内における選択的触媒還元システムは、酸化窒素および一酸化炭素などのような高温排気ガスを意図されるように窒素および水に効果的に変換して、酸化窒素および一酸化炭素が環境に到達するのを防ぐことができる。熱シールド10は、最外層14と、最内層16と、最外層と最内層14、16との間に直接挟まれかつそれらと接触する中間層18とを含む、巻付け可能な壁部13を有する。したがって、最外層14は外部環境Eに直接露出され、最内層16は排気システム12に直接露出され、中間層18は最外層および最内層14、16間に挟まれ、したがって、それは環境Eにも排気システム12にも直接接触してはいない。
