A method for increasing the cetane number of a diesel fuel composition which contains a major proportion of a diesel base fuel, in order to reach a target cetane number X, which method comprises adding to the base fuel an amount x of a fatty acid alkyl ester (FAAE) having a cetane number B greater than the cetane number A of the base fuel, wherein x is less than the amount of the FAAE which would need to be added to the base fuel in order to achieve cetane number X if linear blending rules applied; and the use of a FAAE in a diesel fuel composition for the purpose of reducing the level of cetane improving additives in the composition. The concentration of the FAAE in the overall fuel composition is preferably from 0.05 to 25% v/v.
L'invention concerne un procédé permettant d'augmenter l'indice de cétane d'une composition de carburant diesel contenant une plus grande quantité de carburant de base diesel, pour atteindre un indice de cétane cible X. Ce procédé consiste à ajouter au carburant de base une quantité x d'un ester alkylique d'acide gras (FAAE) possédant un indice de cétane B supérieur à l'indice de cétane A du carburant de base, x étant inférieur à la quantité de FAAE qui devrait être ajoutée au carburant de base pour atteindre l'indice de cétane X si des règles de mélange linéaires s'appliquaient. L'invention concerne également l'utilisation d'un FAAE dans une composition de carburant diesel pour réduire la quantité d'additifs augmentant l'indice de cétane dans la composition. La concentration du FAAE dans la composition de carburant est de préférence comprise entre 0,05 et 25 % en volume.
