Abstract
The use of a complex ester obtainable by esterification reaction between aliphatic linear or branched C2- to C12-dicarboxylic acids, aliphatic linear or branched polyhydroxy alcohols with 3 to 6 hydroxyl groups, and, as chain stopping agents, aliphatic linear or branched C1- to C30-monocarboxylic acids or aliphatic linear or branched monobasic C1- to C30-alcohols, as an additive in a fuel for minimization of power loss in the operation of an internal combustion engine with this fuel.
Claims6
A method of minimizing power loss in the operation of an internal combustion engine, consisting of:
- adding to a fuel a complex ester obtained by an esterification reaction between
- (A) at least one aliphatic linear or branched C2- to C12-dicarboxylic acid,
- (B) at least one aliphatic linear or branched polyhydroxy alcohol with 3 to 6 hydroxyl groups, and
- (C) as a chain stopping agent
- (C1) at least one aliphatic linear or branched C1- to C30-monocarboxylic acid in case of an excess of component (B), or
- (C2) at least one aliphatic linear or branched monobasic C1- to C30-alcohol in case of an excess of component (A).
