Beschreibung
Zusammenfassung:	A diesel fuel composition comprising (a) a quaternary ammonium salt additive; and (b) one or more nitrogen-free detergents; wherein the quaternary ammonium salt additive comprises the quaternised reaction product of a hydrocarbyl substituted succinic acid derived acylating agent and a compound able to react with said acylating agent and which includes a tertiary amine group; wherein each molecule of the hydrocarbyl substituted succinic acid derived acylating agent includes on average at least 1.2 succinic acid moieties. L'invention concerne une composition de carburant diesel comprenant (a) un additif de sel d'ammonium quaternaire ; et (b) un ou plusieurs détergents exempts d'azote ; l'additif de sel d'ammonium quaternaire comprenant le produit de réaction quaternisé d'un agent d'acylation dérivé d'un acide succinique substitué par un hydrocarbyle et un composé pouvant réagir avec ledit agent d'acylation et qui comprend un groupe amine tertiaire ; chaque molécule de l'agent d'acylation dérivé d'acide succinique substitué par hydrocarbyle comprenant en moyenne au moins 1,2 fractions d'acide succinique.
