USE OF ALKOXYLATED POLYTETRAHYDROFURAN AS ADDITIVE IN FUEL Russian patent published in 2019 - IPC C10L1/198 C10L10/18 C10M177/00 C10L10/08 C08G65/20 

FIELD: chemistry.

SUBSTANCE: use of alkoxylated polytetrahydrofuran of general formula (I), in which m is an integer in the range from ≥1 to ≤20, m' is an integer in the range from ≥1 to ≤20, (m+m') is an integer in the range from ≥3 to ≤40, n is an integer in the range from ≥0 to ≤40, n' is an integer in the range from ≥0 to ≤40, p is an integer in the range from ≥0 to ≤25, p' is an integer in the range from ≥0 to ≤25, k is an integer in the range from ≥2 to ≤30, R¹ means an unsubstituted, linear alkyl radical having 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17 or 18 carbon atoms, R² means -CH₂-SN₃, and R³ identical or different means a hydrogen atom or -CH₃, where the chains, denoted by k, are distributed to form a block-polymer structure, and chains labeled with p, p', n, n', m and m', are distributed with the formation of a block-polymer structure or a statistical polymer structure, in combination with at least one additional additive having a detergent effect, as an additive for fuel.

.

EFFECT: use of alkoxylated polytetrahydrofuran in combination with at least one additional additive that has a detergent effect to reduce fuel consumption when the internal combustion engine works with this fuel.
