The invention discloses a gasoline composite additive for vehicles, a preparation method and a use method thereof, and belongs to the technical field of fuel additives. The additive is composed of dimethyl carbonate, high-purity n-tetradecane, isomerized dodecane, isopropylamine, anisole, isooctyl ester, tert-butanol, kerosene, coal tar naphtha, 2-butoxymethanol/butyl Compatible with oxyethanol and polyetheramine. The product has good dispersibility, can effectively improve the octane number and detergency of gasoline, without the need for additional detergent; the addition ratio is small, the cost is low, the compatibility is good, the blending process is simple, the quality is stable, it can enhance the power performance of the car, and the The fuel consumption of automobiles is reduced, the quality is high, and the oxidation stability is extended several times. It does not contain metal or metal ion components. The amount added to the automobile gasoline has no negative impact on the automobile engine and the environment. It is not easy to produce phase separation, the production process and the addition process are simple, the cost is low, and the economic benefit is good. |
