GAS OIL ADDITIVE AND GAS OIL COMPOSITION
An additive for a gas oil having a sulfur content of not more than 0.2 % by weight, characterized by comprising a compound having a hydrocarbon radical with 10 to 22 carbon atoms, an amide group, and an amide group with a hydroxyl group located on a carbon atom at the beta -position relative to the...

Abstract | An additive for a gas oil having a sulfur content of not more than 0.2 % by weight, characterized by comprising a compound having a hydrocarbon radical with 10 to 22 carbon atoms, an amide group, and an amide group with a hydroxyl group located on a carbon atom at the beta -position relative to the nitrogen atom of the amide group; a gas oil composition containing the gas oil additive; and a method for reducing the abrasion of a fuel injection pump or cleaning a fuel injection nozzle by using this composition. The use of this composition can advantageously reduce the abrasion of a fuel pump in a system using a gas oil having a sulfur content of not more thant 0.2 % by weight, particularly 0.05 % by weight, and being likely to cause the abrasion of the pump, and, at the same time, can offer the effect of cleaning an injection nozzle of a diesel engine.
L'invention concerne un additif pour gazole ayant une teneur en soufre d'au plus 0,2 % en poids, se caractérisant en ce qu'elle contient un composé comprenant un radical hydrocarbure à 10 à 22 atomes de carbone, un groupe amide et un groupe amide à groupe hydroxyle situé sur un atome de carbone en position beta par rapport à l'atome d'azote du groupe amide. Elle porte aussi sur une composition de gazole contenant l'additif pour gazole et un procédé de réduction de l'abrasion d'une pompe d'injection de carburant ou de nettoyage d'un injecteur de carburant au moyen de cette composition. L'utilisation de cette composition permet de réduire avantageusement l'abrasion d'une pompe d'injection de carburant dans un système fonctionnant avec du gazole à teneur en soufre d'au plus 0,2 % en poids, particulièrement 0,05 % en poids, et pouvant induire l'abrasion de la pompe, et de nettoyer l'injecteur d'un moteur Diesel. |
