This invention relates to a diesel fuel composition having enhanced lubricity, said composition having a sulphur content of <25ppm and an aromatic content of not less than about 12%, characterised in that the kinematic viscosity measured at 40 ~C (KV40) of the fuel composition is greater than 3.0 cSt. Such compositions have the desired lubricity without having to use or by using in relatively lower amounts of conventional lubricity enhancing additives.
L'invention concerne une composition de carburant diesel possédant un meilleur pouvoir lubrifiant. La composition comprend une teneur en soufre < 25 mg/l et une teneur en aromatiques supérieure ou égale à 12 %, et est caractérisée en ce que la viscosité cinématique mesurée à 40 ·C (KV¿40?) de la composition de carburant est supérieure à 3,0 cSt. Ces compositions possèdent le pouvoir lubrifiant voulu sans avoir à utiliser les additifs améliorant le pouvoir lubrifiant traditionnels, ou en les utilisant en quantités relativement faibles.
