    Abstract: Compositions containing unsaturated fatty esters may be stabilized against atmospheric oxidation by the addition of an antioxidant package containing a phenolic oxidant and a nonphenolic oxygen scavenger, which may be a hydroxylamine, an amine N-oxide, an oxime, or a nitrone. If an amine N-oxide is used, it may be used with or without a phenolic antioxidant. Compositions treated in this manner show good resistance to atmospheric oxidation and resultant viscosity increase.

    Abstract translation: 含有不饱和脂肪酸酯的组合物可以通过加入含有酚氧化剂和非酚类氧清除剂（其可以是羟胺，胺N-氧化物，肟或硝酮）的抗氧化剂包装来稳定抵抗大气氧化。 如果使用胺N-氧化物，则可以使用或不使用酚类抗氧化剂。 以这种方式处理的组合物显示出良好的耐大气氧化性和最终的粘度增加。

    Abstract: This invention is a fuel composition having a sulphur content of null50 ppm by weight and comprising null50 ppm by weight of at least one fused polycyclic aromatic compound which has at least one hetero-atom selected from O and N either (a) as a heterocyclic group, or, (b) as an exocyclic group in which the hetero-atom is attached either directly or through one other carbon atom to a ring carbon atom wherein the fused polycyclic aromatic compound is substituted on at least one of its ring carbon atoms by a C1-C4 alkyl group. These compounds are capable of improving the antiwear and lubricity properties of a low sulphur fuels, especially diesel fuels, when compared with the performance of the same fuel in the absence of such compounds.

    Abstract translation: 本发明是具有<= 50重量ppm的硫含量并且包含≥50重量ppm的至少一种稠合多环芳族化合物的燃料组合物，其具有至少一个选自O和N的杂原子，（a） 作为杂环基，或（b）作为其中杂原子直接或通过一个其它碳原子与环碳原子连接的环外基团，其中稠合多环芳族化合物在其至少一个环上被取代 C 1 -C 4烷基的碳原子。 与不存在这种化合物的相同燃料的性能相比，这些化合物能够改善低硫燃料，特别是柴油燃料的抗磨损和润滑性能。
