Problems solved by technology

[0004] Although methanol gasoline has been developed in China, it has not been popularized. The main reasons are: the first is that the stratification problem cannot be solved well; the second is that there are too many additives in the synthetic gasoline, so that the process Complicated, harmful gas emissions increase, and carbon formation after combustion increases. If the storage time is too long, the aging of synthetic gasoline itself will be accelerated, and combustion and emission will be difficult, which will increase the corrosion of the engine fuel supply system.

Abstract

The invention publishes a kind of carbinol for car, which can replace gas. The weight (or cubage) percentage of raw material follows this. Base gasoline is 47%-62%, industrial carbinol is 36%-50%, emulgator, which weight (or cubage) percentage of raw material composed by 36%-48% methyl tertiary butyl ether, 17%-37% methyl ester, 18%-28% aliphatic alcohol, 1%-10% tert butyl alcohol, is 2%-3%. The cost of gas in this invention is lower, its burning rate is more rapid, the capability of defending heat is less than no time and the heat efficiency is higher, so it can not ablate the engine's system offering oil and contaminants by end gas can be reduced very much, thus, it is good for environment.

Description

Technical field: [0001] The invention relates to an alcohol fuel, in particular to a vehicle methanol gasoline which can be used as a gasoline substitute. Background technique: [0002] With the development of my country's automobile industry, the demand for gasoline will increase, while the storage of underground crude oil will continue to decrease. After a few years, due to the depletion of oil resources, aircraft and cars will be grounded. The ship stops. As we all know, methanol is an alcohol fuel, composed of carbon, hydrogen, and oxygen chemical elements, with an oxygen content of 50%, and has the characteristics of fast combustion speed, fast heat release, and high thermal efficiency; the vapor pressure of methanol is lower than that of gasoline. The vapor volume of gasoline is 2 to 4 times that of methanol vapor. The density of methanol vapor is low, only slightly greater than that of air, and it is easy to diffuse and flow. The vapor density of gasoline is 2 to 5 ti...
