FIELD: chemistry.
SUBSTANCE: additive for low-sulphur diesel fuel based on carboxylic acids contains polyethylene polyamine, and the carboxylic acids used are commercial-grade alkyl(C16-C18)salicylic acids with weight ratio of polyethylene polyamine to commercial-grade alkyl(C16-C18)salicylic acids of 0.007-0.035:1.0.
EFFECT: improved lubrication properties of low-sulphur diesel fuel; the additive also meets emulsion property requirements, does not promote formation of a fuel-water emulsion and provides compatibility with cetan number enhancing additives.
