1. A composition of fuel additives comprising at least:
a first additive comprising a triazole derivative of the following formula (I):in which:
R1 is selected from a group comprising a hydrogen atom, a linear or branched C1 to C8 aliphatic hydrocarbon group, a carboxyl group (—CO2H), R2 and R5 are identical or different and represent, independently of one another, a group selected from a group comprising a hydrogen atom and a linear or branched, saturated or unsaturated C1 to C33 aliphatic hydrocarbon group, optionally comprising one or more oxygen atoms in a form of a carbonyl function (—CO—) and/or carboxyl function (—CO2H), the R2 and R5 groups optionally forming together a ring with 5 to 8 atoms comprising nitrogen, to which R2 is bound, it being understood that in this case R2 and R5 then constitute one and the same linear or branched, saturated or unsaturated C1 to C33 aliphatic hydrocarbon group, optionally substituted with one or more oxygen atoms in the form of a carbonyl function (—CO—) and/or carboxyl function (—CO2H), R3 and R4 are identical or different and represent, independently of one another, a group selected from a group comprising a hydrogen atom and a linear or branched, saturated or unsaturated, cyclic or acyclic aliphatic hydrocarbon group, having from 2 to 200 carbon atoms; (b) a second additive comprising a quaternary ammonium salt obtained by reaction of a nitrogen-containing compound comprising a tertiary amine function with a quaternizing agent, the nitrogen-containing compound being selected from: (i) a product of reaction of an acylating agent substituted with a hydrocarbon group and of a compound comprising at least one tertiary amine group and a group selected from the primary and secondary amines and the alcohols, (ii) a product of the Mannich reaction comprising a tertiary amine group; and (iii) amines substituted with a polyalkene group having at least one tertiary amine group. |
