ANTI-WEAR ADDITIVE TO DIESEL FUEL WITH ULTRA-LOW CONTENT OF SULFUR Russian patent published in 2020 - IPC C10L1/224 C10M157/00 C10L1/10 C10L10/08 C10L1/04 C10L1/226 C10M157/04 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil refining and petrochemistry, particularly, to additives to low-sulfur diesel fuel, which improves its lubricating properties. Composition of anti-wear additive to low-sulfur diesel fuel based on esters of organic acids, amido-imidazolines and amines is characterized by that it contains esters obtained by means of esterification of fatty acids of various vegetable oils, and the additive further contains amido-imidazolines and amines containing from 21 to 31 carbon atoms, with the following ratio of components, wt%: esters obtained by esterification of fatty acids of various vegetable oils 40–41; amido-imidazoline 36–37; amines containing 21 to 31 carbon atoms, the rest.

EFFECT: technical result consists in improvement of lubricating power of diesel fuel with ultralow content of sulfur, which increases service life of diesel engine, prevents premature wear of fuel equipment parts.
