Abstract
Description
本発明は、内燃エンジン、およびより具体的には直接噴射ディーゼルエンジン、への燃料供給方法を含む。本発明は、前記方法において利用される燃料組成物、燃料添加剤組成物および燃料添加剤それら自体も記載する。前記方法は、それらが使用されるエンジン内の向上したデポジット制御を含み、腐食防止を向上させることもできる。一部の実施形態において、前記デポジット制御用添加剤には窒素がなく、結果として得られる燃料組成物および燃料添加剤組成物は、限られた量の窒素、または一部の実施形態では限られた量の塩基性窒素および/もしくはアミン窒素を含有し得る。
本発明は、エンジン内のデポジット制御を向上させる方法を提供し、向上した腐食防止も場合によりもたらす。前記方法は、内燃エンジンを、本明細書に記載する窒素不含デポジット制御用添加剤を含む燃料組成物をそのエンジンに供給することにより、動作させることを含む。
本発明に利用される燃料組成物は、本明細書に記載する燃料添加剤と液体燃料とを含み、内燃エンジンへの燃料供給に有用である。前記燃料組成物は、1つ以上の追加の性能添加剤も含むことがある。
本発明の方法は、酸の形態または無水物の形態の少なくとも2つのカルボキシ官能基を有する置換炭化水素を含むデポジット制御用添加剤を利用する。一部の実施形態において、前記添加剤は、酸または無水物の形態の少なくとも2つのカルボキシ官能基で置換された炭化水素である。他の実施形態において、前記添加剤は、ヒドロカルビル置換コハク酸アシル化剤である。他の実施形態において、前記置換炭化水素添加剤は、二量体酸化合物である。さらに他の実施形態において、本発明の置換炭化水素添加剤は、この項で説明する2つ以上の添加剤の組み合わせを含む。記載材料の部分エステルも本発明により考えられ、ここに含まれる。
本発明の添加剤組成物および燃料組成物は、1つ以上の追加の性能添加剤をさらに含むことがある。追加の性能添加剤は、内燃エンジンのタイプおよびそのエンジンにおいて使用される燃料のタイプ、その燃料の品質、ならびにそのエンジンが運転されているときの使用条件を含む幾つかの要因に依存して、燃料組成物に添加され得る。

(R4C(O)(R5)nC(O))R4 (IV)
および
によって表される少なくとも1つのカルボン酸反応体と、式(I)によって表されるオレフィン結合を含有する任意の化合物との反応から製造することができる。これらの化合物を製造するための化合物およびプロセスは、参照により本明細書に援用されている、米国特許第5,739,356号;同第5,777,142号;同第5,786,490号;同第5,856,524号;同第6,020,500号;および同第6,114,547号に記載されている。
1セットの実施例を調製し、XUD9ノズルコーキング試験で試験する。この試験には、1.9L 4気筒Peugeot XUD 9エンジンを使用し、それを58Nmの負荷下で6時間、3000RPMで運転する。試験開始時、新しいノズルに空気を流し、0.1mmのリフト点で測定を行う。ノズルをエンジン上で再び組み立てて、試験条件まで温めて、6時間運転する。その後、ノズルに空気を再び流し、初期流量と比較する。指定合格/不合格限度はないが、0.1mm測定値での15%残存インジェクタ流量の結果が一般に最低合格成果であると考えられる。実施例セット1における各実施例を従来の無硫黄ディーゼル燃料で運転する。これらの実施例の配合および得られた結果を下の表にまとめる:
2 − 窒素不含清浄剤は、1000数平均分子量(Mn)ポリイソブチレンおよびジカルボン酸から誘導したポリオレフィン酸である。
1セットの実施例を調製し、SG−F−098と呼ばれるCEC DW10ディーゼル燃料インジェクタ汚損試験で試験する。この試験には、2.0L、4気筒Peugeot DW10直接噴射、ターボチャージャー付き、コモン・レール・エンジンを使用する。試験手順は、新しいインジェクタの16時間の初期なじみ期間(bedding−in period)、続いて8時間のサイクル運転期間、次いで4時間の浸漬期間を含み、この順路を32時間の運転時間にわたって繰り返す。この試験は、32時間のエンジン運転時間後のエンジンパワー損失を報告する。エンジン損失値が低いほど、低いインジェクタ汚損レベルを示す。インジェクタ汚損レベルが低いほど、良好な清浄性を示す。実施例2−A、2−Bおよび2−Cを無硫黄ディーゼル燃料で運転する。少量の亜鉛(2ppm)も各試料に添加する。実施例2−Dおよび2−Eを、実施例2−A、2−Bおよび2−Cで使用するディーゼル燃料と追加のバイオディーゼルの90:10ブレンドであるブレンドで運転する。これらの実施例には亜鉛を添加しない。それらの実施例の配合およびおよび得られた結果を下の表にまとめる:
2 − 窒素含有清浄剤は、1000数平均分子量(Mn)ポリイソブチレンから誘導したスクシンイミド分散剤である。
