Abstract

The invention provides an energy-saving and environment-friendly gasoline additive with a maintenance function and a preparation method thereof. Ethanol is taken as a main raw material, and benzyl alcohol, butanol and n-caprylic alcohol are taken as auxiliary raw materials. Due to addition of propylene glycol tert-butyl methyl ether, fatty acid amide polyoxyethylene ether and cyclohexyl glycidyl ester ether, the distillation range temperature of gasoline is reduced, the combustion performance is improved, the driveability index of an automobile is increased, and environment pollution is reduced; secondarily, through a synergistic effect of isopropyl nitrite and 4-pentyldicyclohexylanone, the fuel saving ratio is increased, energy is saved, and coking of carbon deposit is reduced; then, a cerium-source catalyst generates particles in the combustion process, the particles are dispersed in a cylinder and an exhaust system, incomplete combustion hydrocarbons can be catalytically oxidized and have a synergistic effect with diethylenetriamine and 4-pentyldicyclohexylanone, and generation of carbon-containing deposits and exhausting of waste gas are effectively reduced. Therefore, the prepared energy-saving and environment-friendly gasoline additive with the maintenance function can increase the octane value of the automobile and purify tail gas.

Description

technical field [0001] The invention relates to the technical field of gasoline additives, in particular to an energy-saving and environment-friendly maintenance gasoline additive and a preparation method thereof. Background technique [0002] With the continuous enhancement of people's awareness of environmental protection and increasingly stringent environmental protection requirements, all countries in the world attach great importance to the improvement of gasoline quality. Western developed countries have implemented unleaded gasoline programs since the 1980s, and most countries currently prohibit the use of leaded gasoline. With the increasing number of automobiles, the reduction of petroleum resources and the increasingly stringent environmental regulations, reducing fuel consumption and improving emissions have become the top priority of gasoline engine research. In addition to improving the engine itself, it is also feasible to use additives to improve fuel quality....
