    Abstract: This invention is a fuel composition having a sulphur content of /= 50 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: 本发明是硫含量为重量百分比为50ppm且包含≥50ppm重量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(或者 a)作为杂环基团,或(b)作为其中杂原子直接或通过另一个碳原子连接到环碳原子上的环外基团,其中稠合多环芳族化合物在至少一个 其环碳原子由C1-C4烷基组成。 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。
