High-ratio methanol fuel composite additive for vehicles

Abstract

The invention discloses a high-ratio methanol fuel composite additive for vehicles. The composite additive is prepared from the following raw materials in percentage by mass: 50-70% of aliphatic ester, 10-30% of nitrate, 5-10% of glycerol, 5-10% of benzotriazole and 5-10% of high carbon alcohol. According to the high-ratio methanol fuel composite additive, the aliphatic ester of which the carbon chain number is about 18 is adopted, and the lubricating property, corrosion resistance and wear resistance of the methanol fuel for vehicles can be greatly improved. The nitrate is an excellent ignition improver and combustion improver, and the glycerol, benzotriazole and high carbon alcohol are excellent corrosion inhibition components and cosolvents. According to the methanol fuel composite additive for vehicles prepared by mixing the substances, the performance of the fuel is greatly improved.

Description

technical field [0001] The invention belongs to the functional composite fuel additive, which can obviously solve and improve the disadvantages of high-proportion methanol gasoline such as poor lubricity, reduced power, strong corrosion and the like. Background technique [0002] Methanol is not only an important chemical raw material, but also one of the cleanest fuels. At present, the world's oil resources are decreasing day by day, the problem of PM2.5 is becoming more and more prominent, the development of electric vehicles worldwide is frustrated, and the industrialization of methanol fuel and methanol vehicles has increasingly attracted the attention and attention of all walks of life. The methanol economy is quietly rising, which is attracting much attention emerging industries. With the promulgation of two methanol fuel national standards GB / T23799-2009 "Methanol Gasoline for Vehicles (M85)" and GB / T23510-2009 "Methanol Fuel for Vehicles", and the "two provinces and...

AI Technical Summary

Problems solved by technology

[0004] However, methanol gasoline, especially high-proportion methanol gasoline, has the following phenomena in the long-term use process: the decrease in fuel lubricity will cause wear and tear on automotive fuel injectors and fuel pumps, which is determined by the fuel characteristics of methanol itself; fuel has a strong Corrosiveness, especially the increase of corrosiveness to metals such as aluminum, copper, zinc, etc., will cause a certain amount of metal compound impurities in the fuel supply system, causing blockage of some parts or increased wear; the latent heat of vaporization of methanol is large, and the calorific value Lower, resulting in slightly poorer ignition performance when burning methanol

Due to the existence of the above phenomena, when the car burns methanol, it is easy to cause early damage to the fuel injector, shorten the life of the fuel pump, frequently replace the fuel filter, reduce the power of the car, and increase the fuel consumption.
