FUEL COMPOSITION Russian patent published in 2009 - IPC C10L1/22 C10L1/226 C10L1/222 

FIELD: chemistry.

SUBSTANCE: invention relates to oil refining and petrochemistry, specifically to a fuel composition designed for internal combustion engines. A hydrocarbon-based fuel composition for internal combustion engines is proposed, which contains an aromatic amine and is distinguished by that it also contains a multifunctional additive, which is a mixture of polyisobutylene-monoamine, polyester and corrosion inhibitor, polyethylenepolyamine of general formula H₂N-(CH₂-CH₂-NH-)_nH, where n=1-5, and a solvent, with the following ratio of components, wt %: aromatic amine 0.6 to 1.6; multifunctional additive 0.03 to 0.07; polyethylenepolyamine 0.0001 to 0.004; solvent 0.2 to 0.7; hydrocarbon base up to 100. The solvent is selected from: 2-ethylhexanol, toluene, xylene. The hydrocarbon base used in the fuel composition is a mixture of hydrocarbon fractions which boil at temperature between 25 and 220°C. The proposed fuel composition has good anti-detonation, detergent and anticorrosion properties and is made from industrially produced products.

EFFECT: use of the invention allows for obtaining high quality motor fuel: AI-92 (Regular-92), AI-95 (Premium-95), AI-98 (Super Euro-98).
