AI Technical Summary

Problems solved by technology

[0003] Methanol gasoline has been popularized day by day, but there are also shortcomings found in the promotion: although additives are added to most methanol gasoline, but because the effect of the additive is not very prominent and because methanol itself is very corrosive, it will only relatively slow down the impact of methanol on gasoline. Corrosion of engine and other components, but not much improvement in other performance of the car, such as service life, storage stability, low temperature operation performance, cold start performance, etc., and the power performance is relatively weakened
Methanol has strong polarity, and the methanol gasoline formed has poor stability, and it is prone to turbidity and stratification when it encounters a small amount of water or a low temperature environment; when driving, methanol gasoline will be prone to gas block in summer and difficult to ignite in winter; the calorific value of methanol is higher than that of gasoline value is low, with the increase of the proportion of methanol in the fuel, the consumption of methanol gasoline increases significantly

Description

technical field [0001] The invention relates to the technical field of fuels, in particular to a multifunctional gasoline additive, a preparation method thereof and a mixed fuel containing the multifunctional gasoline additive. 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. The method of introducing additives into the fuel to improve the combustion efficiency of the fuel in the combustion chamber of the internal combustion engine has been widely develo...
