The invention relates to a low-sulphur diesel fuel containing a maximum of 0.2 wt. % sulphur and fatty acid monoalkyl esters in an amount between 10 and 50,000 ppm as lubricant improver, whereby the fatty acid ester of the fatty acid monoalkyl ester is derived from at least 50 %, in particular at least 70 % of saturated fatty acids. It has been shown that said fatty acid esters exhibit a markedly better lubricant improvement in low-sulphur fuels than biodiesel derived from rapeseed oil or soya oil.
L'invention concerne un carburant diesel à faible teneur en soufre, qui contient au maximum 0,2 % en poids de soufre et des esters monoalkyliques d'acides gras, dans une quantité comprise entre 10 et 50.000 ppm, comme agents améliorant le pouvoir lubrifiant. Le carburant diesel selon l'invention est caractérisé en ce que les restes acides gras des esters monoalkyliques d'acides gras proviennent à au moins 50 %, notamment à au moins 70 %, d'acides gras saturés. Il a été démontré que ces esters d'acides gras entraînent une amélioration du pouvoir lubrifiant dans le carburant diesel à faible teneur en soufre significativement meilleure que des biodiesels à base d'huile de colza ou d'huile de soja.
