    Abstract: This invention is a fuel composition having a sulphur content of ≦50 ppm by weight and comprising ≧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: A composition and method for improving the performance, and thus, also the fuel economy, of an internal combustion engine by introducing a fuel additive into the engine's fuel supply to enhance fuel lubricity. The composition can feature a mixture of esters, glycol ether, and a solvent. The mixture of esters can include adipate esters, azelate esters, dodecanedioate esters, sebacate esters, or phthalate esters. Esters that may be used to create the composition can include a mixture of two or more adipate esters such as, for example, an adipic acid ester, a glutaric acid ester, and a succinic acid ester. The composition can further feature a smoke suppressant that can be an organometallic soap. The organometallic soap can be an iron salt of a fatty acid such as, for example, ferrocene. The composition can be used as a combustion modifier fuel additive and as a lubricating oil.
