MOTOR FUEL ADDITIVE Russian patent published in 2008 - IPC C10L1/222 C10L1/223 C10L1/30 C10L1/192 

FIELD: fuel additives.

SUBSTANCE: invention relates to composition of additives for use in motor fuel designed for internal combustion engines. Additive based on fuel-compatible liquid carrier contains 0.5-1.5% of burning stabilizer based on urea derivatives: (A), wherein R₁ represents substituted or unsubstituted aryl, alkyl, or alkenyl radical, R₂ hydrogen, aryl or alkyl radical, X substituted or unsubstituted amino group; 0.01-0.03% of nano-sized (not larger than 300 nm) cerium oxide particles pretreated with 0.1-0.5% of liquid polyether-based synthetic lubricating material having density 0.91 to 0.96 g/cm³ at 200°C, viscosity index 125 to 163, and flash point 250-320°C. A second variant of additive is described additionally containing 0.01-0.03% of fatty acid salts with polyvalent metals in the form of 50-80% zirconyl oleate in hydrocarbon solvent. Compound A is contained in additive in concentration 1.1 to 4.5%. Other components are contained in the same amount.

EFFECT: increased energetic characteristics of engine and reduced toxicity of exhaust gases.
