Problems solved by technology

Although MMT and MTBE and other series of unleaded gasoline antiknock products can solve the problems such as lead pollution, adding antiknock agent MMT and antiknock additive MTBE in oil products will cause greater pollution to the environment. The emission of element Mn will directly affect human beings and other organisms, and seriously pollute various water sources. MTBE will not only pollute groundwater sources, but also emit a large amount of nitrogen oxides when used in gasoline combustion, causing serious air pollution.
Patent CN103540372A discloses a gasoline additive in which a large amount of MTBE (methyl tert-butyl ether) is added. Although the octane number of gasoline is increased, the emissions produced by it will cause serious damage to air and water sources. Pollution, poor environmental performance

Abstract

The invention discloses an energy-saving emission-reducing gasoline additive and a preparation method and application thereof, and belongs to the technical field of fuels. The energy-saving emission-reducing gasoline additive is prepared from denatured fuel ethanol, 2-ethyl hexanol, isopropyl alcohol, methylbenzene, ethyl tert butyl ether, paraffin hydrocarbon solution, a nonionic surfactant, bis-(3-triethoxysilylpropyl)-tetrasulfide, polyoxyethylene sorbitan fatty acid ester, ethyl nitrate and isooctyl nitrate; the energy-saving emission-reducing gasoline additive is applicable to fuel oils,has low addition quantity, high combustion efficiency, low gasoline consumption and good cleaning effect, emission of pollutants is decreased, and environmental pollution is relieved.

Description

technical field [0001] The invention relates to an energy-saving and emission-reducing gasoline additive, a preparation method and application thereof, and belongs to the technical field of fuels. Background technique [0002] A large number of long-term studies have shown that fuels such as gasoline or diesel are burned in a very short moment in the engine combustion chamber, that is, they are discharged, such fuels are not completely burned, and the remaining fuel is burned as intermediate products of combustion or even unburned. This will not only reduce the fuel usage rate, but also cause a large amount of harmful gases, such as hydrocarbons and intermediate products of incomplete combustion of fuel oil, to be discharged into the air and pollute the environment. [0003] Since the automobile engine came into the market, in order to improve the combustion efficiency of the engine, people are trying to improve the compression ratio of the automobile engine. From 4.0 to 10...
