Description
本出願は、2010年11月19日に出願された米国仮特許出願第61/458,199号に対して米国特許法第119条の下で利益を主張し、その内容は参照により本明細書に組み込まれている。
本発明は概して、燃料噴射器などのエンジン燃料送達システムから堆積物を洗浄する方法に関する。
自動車エンジンは、炭化水素燃料の酸化及び重合のため、例えば、キャブレータポート、スロットルボディ、燃料噴射器、吸気ポート、吸気弁、及び燃焼室などのエンジンコンポーネントの表面に堆積物を形成しがちであることがよく知られている。これらの堆積物は、比較的少量で存在する場合でさえも、しばしば失速及び加速不良などの著しい操縦性の問題を引き起こす。さらに、エンジン堆積物は、自動車の燃料の消費及び排ガス汚染物質の生成をかなり増加させ得る。したがって、このような堆積物を防止又は抑制するのに有効な燃料洗浄剤又は「堆積抑制」添加剤の開発は、非常に重要であり、多数のこのような材料が当技術分野で公知である。しかし、多量の堆積物及び/又は頑強な堆積状況にさらされた噴射器及び他のコンポーネントは、燃料洗浄剤を用いた後でさえ、最適性能を維持するために時々のさらなる洗浄を必要とする。
(式中、Rは、水素又は置換若しくは非置換のC1からC30ヒドロカルビル基であり、R1は、置換又は非置換のC1からC30ヒドロカルビル基であり、nは、1から4の整数である)
で表される1種又は複数のプロピレングリコールエーテルを含む洗浄組成物を導入する段階を含む方法が提供される。
(式中、Rは、水素又は置換若しくは非置換のC1からC30ヒドロカルビル基であり、R1は、置換又は非置換のC1からC30ヒドロカルビル基であり、nは、1から3の整数である)で表される。一実施形態において、Rは、水素であり、R1は、置換又は非置換のC1からC6ヒドロカルビル基である。別の実施形態において、R及びR1は、同じであり又は異なり、置換又は非置換のC1からC6ヒドロカルビル基であり得る。一実施形態において、nは2である。
(式中、R3は、約600から約5,000の範囲の平均分子量を有するポリアルキル基であり;R4及びR5は、独立して、水素又は1から6個の炭素原子を有する低級アルキルであり;Aは、アミノ、アルキル基中に約1から約20個の炭素原子を有するN−アルキルアミノ、それぞれのアルキル基中に約1から約20個の炭素原子を有するN,N−ジアルキルアミノ、又は約2から約12個のアミン窒素原子及び約2から約40個の炭素原子を有するポリアミン部分である)
を有するものが含まれる。
[式中:R6は、ニトロ又は−(CH2)n−NR11R12(ここで、R11及びR12は、独立して、水素又は1から6個の炭素原子を有する低級アルキルであり、nは、0又は1である)であり;R7は、水素、ヒドロキシ、ニトロ又は−NR13R14(ここで、R13及びR14は、独立して、水素又は1から6個の炭素原子を有する低級アルキルである)であり;R8及びR9は、独立して、水素又は1から6個の炭素原子を有する低級アルキルであり;R10は、約450から約5,000の範囲の平均分子量を有するポリアルキル基である]
のものが含まれる。
(式中、R15は、約1から約30個の炭素原子を有するヒドロカルビル基であり;R16及びR17は、それぞれ独立して、水素又は約1から約6個の炭素原子を有する低級アルキルであり、それぞれのR16及びR17は、それぞれ−O−CHR16−CHR17−単位において独立して選択され;Aは、アミノ、アルキル基中に約1から約20個の炭素原子を有するN−アルキルアミノ、それぞれのアルキル基中に約1から約20個の炭素原子を有するN,N−ジアルキルアミノ、又は約2から約12個のアミン窒素原子及び約2から約40個の炭素原子を有するポリアミン部分であり;mは、約5から約100の整数である)
を有するものが含まれる。
・0=有効でない=堆積物は視認可能なほど変化せず、洗浄溶液は、変色しなかったか又は濁らなかった。
・1=わずかに可溶性=洗浄溶液のわずかな濁り及び/又は変色があったが、堆積物の外観における変化はなかった。
・2=半可溶性=溶液は濁った状態になり、及び/又は変色し、堆積物はサイズが減少した。
