The world today, the energy and environment are the principal elements that influences the global economy social sustainable development.High speed development along with world economy, also in continuous increase, and energy expenditure had both needed to consider the environmental protection factor, was subjected to the number of resources quantitative limitation again to the demand of oil, along with the minimizing of prospective oil and the more and more strictness of environmental requirement, must seek the development and utilization of new forms of energy.How to solve above-mentioned two large problems with making overall plans and coordinate, caused extensively showing great attention to of internal and international society.Each state drops into a large amount of manpowers, financial resources etc. and carries out the new substitute energy of multi-faceted research and development all in specific national conditions, resource situation according to this country, to satisfy the needs of this country's development.
As everyone knows, the national conditions of China are oil starvation, weak breath, relative rich coal, and the most important condition of substitute energy must possess two big key elements, the one, and reserves are big, and the 2nd, burning is clean.Yet China but has the abundant spare time to abandon the abundant coal-seam gas of the high sulphur coal of few usefulness and reserves and the byproduct coke(oven)gas of coking charcoal, therefore can utilize them to make fuel such as methyl alcohol, dme.The energy strategy of China also is " save preferentially, base on our country, coal be basic, multiple development ", thereby has established solid basis for the further expansion production of the development of methanol fuel and carbinol derivatives product production.Though in the research of methanol fuel and utilization, all obtained interim achievement for many years, but because of being subjected to the restriction of Aalcohols fuel characteristic, cause in research the high density Aalcohols fuel, substantially all be to lean on the requirement of existing spark ignition engine being transformed and reached adaptation high density Aalcohols fuel, and performance Aalcohols fuel advantage.Because using the influence that is subjected to its characterization factor on available engine, Aalcohols fuel has a lot of defectives:
1. alcohols (main nail alcohol, ethanol) fuel is a kind of good polar organic solvent, has stronger chemically reactive, very easily makes automobile-used metalwork corrosion, causes the swelling of rubber and plastic component, softening, be full of cracks and aging in advance etc.
2. Aalcohols fuel is low because of calorific value, and vaporization heat is big, thereby cold cranking capacity is poor, cold operation worsens, and oil consumption increases.
3. Aalcohols fuel is low because of boiling point, thereby vehicle moves under long-play or high temperature and be prone to vapour lock, the fuel feeding difficulty or the phenomenon of fuel feeding not occur.
4. Aalcohols fuel and base oil intermiscibility are poor, because of layering appears in factors such as moisture, temperature or mixed-fuel burning proportion easily.
Must transform available engine when 5. using the high-content Aalcohols fuel, technical difficulty is big, and cost increases, and it is poor to exchange usability, and engine versatility problem is difficult to solve.
Summary of the invention
The object of the present invention is to provide a kind of stable performance, need not to change the high-content alcohol-ether fuel that has the spark ignition engine structure now.This fuel with now use gasoline interchangeability and compatibility good, thereby reduced the undue dependency of existing spark ignition engine significantly to gasoline, even do not having under the prerequisite of gasoline, also can normally use this kind fuel separately, improved the emergency guarantee degree of country on the energy.
The objective of the invention is to realize by following technical proposals:

The compound method of high-content alcohol ether class A fuel A of the present invention is: at normal temperatures and pressures additive and methyl alcohol or ethanol or first, second alcohol mixture are mixed according to the parts by weight metering, static reaction can use after 10～60 minutes then.
The present invention is to be main raw material with methyl alcohol or ethanol or first, ethanol alcohol mixture, in addition after part higher alcohols, part lighter hydrocarbons solvent and ether, ketones solvent and other a little auxiliary, solve many shortcomings of being brought because of its inherent characteristic when high-content first, alcohol fuel uses on existing spark ignition engine, be embodied in the following aspects:
A, high-content Aalcohols fuel are low because of calorific value, and vaporization heat is big, causes cold cranking capacity poor, and cold operation worsens, and oil consumption increases.The present invention is by after adding an amount of higher alcohols, lighter hydrocarbons and ether, ketones solvent, the calorific value that makes this fuel is near the calorific value of gasoline, its saturated vapor pressure also is improved simultaneously, reached the flammable limit of gas mixture, realize normal starting under low temperature (about 20 ℃), solved the problem of cold starting difficulty.The height of Aalcohols fuel itself contains oxygen characteristic in addition, lean burning ability preferably, and because of the raising of calorific value, thus improved the thermo-efficiency of engine, reduced oil consumption, remain basically stable with the gasoline consumption, use properly also can descend 5%～12%.
B, the high-content Aalcohols fuel is on the low side because of boiling point, occurs vapour lock easily when hot operation or engine move for a long time, causes the smooth or fuel cut-off of fuel feeding.After the present invention has added the alcohols, light hydrocarbon solvent of boiling range scope higher (80～180 ℃), make the whole combustion processes of fuel all reach the requirement of the whole trouble-free burning operation of spark ignition engine, solved the vapour lock problem.
C, Aalcohols fuel are a kind of good polar organic solvents, have stronger chemically reactive, and formic acid that produces in combustion processes or acetate can make metal materials such as copper, aluminium, manganese produce corrosion, and these materials are typical materials of Fuel Petroleum automobile.Simultaneously, formic acid that is produced in the combustion processes or acetate also produce certain slight corrosion to automobile sealed rubber and other synthetic non-metallic material, and rubber, plastic are played swelling, softening or be full of cracks effect, and make these materials aging in advance.
Adding in the fuel of the present invention has a certain amount of metal cleaning, metallic corrosion to suppress solvent and rubber and plastic spare swelling inhibitor, make the high-content vehicle alcohol ether fuel all drop to very low scope, make the problems referred to above obtain fine solution the corrosion and the degree of swelling of corrosion of metal degree and rubber and plastic spare.
D, because of Aalcohols fuel very easily absorbs water, after temperature or lighter hydrocarbons solvent oil and other auxiliary agent surpass certain index because of moisture content, be prone to liquid phase separation, influence is used.The present invention by the emulsification solubility promoter and bipolarity group solvent that add doses after, the highest temperature of dissolving each other can be reduced to very low, thereby ensured the trouble-free burning of this fuel.
