La présente invention a pour objet l'utilisation, pour améliorer les propriétés de détergence d'une composition de carburant liquide comprenant un ou plusieurs additifs de détergence, d'un additif constitué d'un ou plusieurs composé(s) hydrocarboné(s) comprenant de 2 à 10 atomes de carbone et deux fonctions hydroxyle. La présente invention porte également sur un procédé d'amélioration de la propreté et/ou de nettoyage d'au moins une partie interne d'un moteur à combustion interne alimenté par un carburant liquide comprenant un ou plusieurs additifs de détergence, consistant à ajouter à ladite composition de carburant un tel composé hydrocarboné. The present invention relates to the use, for improving the detergency properties of a liquid fuel composition comprising one or more detergent additives, of an additive consisting of one or more hydrocarbon compound(s) comprising from 2 to 10 carbon atoms and two hydroxyl functions.The present invention also relates to a method for improving the cleanliness of and/or for cleaning at least one inner portion of an internal combustion engine supplied with a liquid fuel comprising one or more detergent additives, wherein such a hydrocarbon compound is added to the fuel composition.
