FIELD: chemistry.
SUBSTANCE: additive represents solution of highly-molecular polyisobutylene, which has molecular weight from, approximately 3.7·106 to, approximately 4.9·106, in used hydrocarbon liquid. Hydrocarbon liquid for machines with hydraulic systems with thermo- and/or energy-strained operation conditions contains additive in amount, ensuring energy characteristics of said machines. Mainly, hydrocarbon liquid represents kerosene or aviation spirit or Diesel fuel or liquid jet fuel. Liquid hydrocarbon fuel for jet engines contains additive in amount ensuring concentration of highly-molecular polyisobutylene in liquid hydrocarbon fuel from 0.015 to 0.095 wt %.
EFFECT: improvement of operating energy characteristics of machines, efficiency of engines, pump force.
