Description
Technical field
The present invention relates to fuel technology field, relate in particular to a kind of spark ignition engine methanol fuel.
Background technology
Spark ignition engine is a kind of burning utilizing fuel, is heat energy by the converts chemical energy of fuel, and then is the oil engine of mechanical energy by piston by thermal energy.Spark ignition engine can adopt methanol gasoline replacing gasoline as fuel.Methanol gasoline is in existing gasoline or gasoline component oil, add the dissimilar additive such as methyl alcohol and various solubility promoter, metal protection agent, rubber protective material, cold-starting agent, calorific value synergistic agent; additive composition is different; the ratio used is different, and its effect brought and impact are also just variant.In the prior art, the add-on of methyl alcohol is 5% ~ 20%, in the majority to add 15%; Advantage is that the capability of antidetonance is good, and combustion cleaning is functional, and shortcoming is to petrolic corrodibility and all comparatively large to the swelling ratio of elastomeric material, and is easy to layering, and poor in low-temperature operability and cold-start performance, and dynamic performance is also not as good as pure gasoline.Due to domestic methyl alcohol aboundresources, and methanol usage in methanol gasoline is generally less, is unfavorable for the balance of Energy resources.Common methanol gasoline additive complicated, consumption is large, and cost is high, and additive composition easily conflicts each other in practice, and causes some technical problems, brings disadvantageous effect, or even potential safety hazard.Because solve the acidic substance such as formaldehyde, formic acid that methyl alcohol produces in combustion to add metal protection agent to corrosion of metal problem, and these metal protection agent can produce swelling action to automobile rubber parts, cause the problem of swell rubber.Vice versa, and when solving swell rubber problem, the rubber protective material added can produce certain corrodibility to metal and cause new problem again.Visible, the problem that methanol gasoline of the prior art causes due to additive component complexity is comparatively serious.
Methanol fuel normally by methyl alcohol and gasoline by solubility promoter process, allow methyl alcohol and gasoline form uniform mixture, burned for energy together with gasoline thus propelling vehicle engine.In current methanol fuel industry, cost is also one of important references factor of technological innovation degree.The additive of methanol fuel of the prior art, one of its main composition is solubility promoter, and solubility promoter is low-carbon (LC) alcohols mostly, and price is higher, and usage quantity is in the prior art scheme very large, is generally more than 3% of total inventory, causes production cost to improve.
Applicant, by constantly making great efforts and great many of experiments, have developed a kind of alternative gasoline, is suitable for the novel carbinol fuel that spark ignition engine uses.
Summary of the invention
The object of the present invention is to provide a kind of spark ignition engine methanol fuel, solve the additive component complexity of methanol fuel in prior art and initiation is corrosive to metal, rubber is had to the problems such as swelling action, solve the large usage quantity of methanol gasoline additive, the problem that cost is higher simultaneously.
Technical scheme of the present invention is as described below.
A kind of spark ignition engine methanol fuel, comprises methyl alcohol, additive, gasoline or gasoline component oil, and the volume percent of raw material is:
Methyl alcohol 5% ~ 85%;
N-octyl amine 0.05% ~ 0.8%;
All the other are gasoline or gasoline component oil;
Each raw material to be filled a prescription mixing and stirring according to above-mentioned raw materials.
The volume percent of described methyl alcohol is 10% ~ 80%.
The volume percent of described methyl alcohol is 15% ~ 75%.
The volume percent of described methyl alcohol is 25% ~ 65%.
The volume percent of described methyl alcohol is 35% ~ 55%.
The volume percent of described n-octyl amine is 0.2% ~ 0.65%.
The volume percent of described n-octyl amine is 0.35% ~ 0.5%.
20 ~ 60min is stirred after described raw material mixing.
Described gasoline component oil for composition be the alkane of C5 ~ C12.
Spark ignition engine methanol fuel of the present invention is used for petrolic application.
Technical solution of the present invention according to as described below.
Methyl alcohol is polar solvent, and gasoline is alkane (non-polar solvent), and both mix needs to add solubility promoter.Conventional low-carbon (LC) co-solvent has a hydroxyl (-OH) and alkyl (-R), and hydroxyl (-OH) is polar group, and alkyl (-R) is non-polar group.According to the similar principle that mixes, the polar group hydroxyl (-OH) of methyl alcohol is connected with the hydroxyl (-OH) of low-carbon (LC) co-solvent, the non-polar group alkyl (-R) of gasoline is connected with the non-polar group alkyl (-R) of low-carbon (LC) co-solvent, thus allow together with the methyl alcohol of polarity and nonpolar gasoline can be mixed by the anastomosis of solubility promoter, form uniform mixture.
The present invention adopts gasoline or gasoline component oil to be raw material, and wherein, gasoline component oil is commercially available prod.Adopt gasoline or gasoline component oil all can, facilitate compounding methanol fuel, the use being conducive to product is promoted.In the present invention, gasoline component oil adopts composition to be the alkane of C5 ~ C12, can obtain better effect.In order to more supplement the deficiency of petroleum resources, high concentration methanol fuel is imperative simply and efficiently to develop composition.The present invention expands the usage quantity scope of methyl alcohol, and handiness is large and ensure that result of use.
In order to solve the metallic corrosion or the problem such as swell rubber that methanol fuel causes because of additive component complexity, creationary of methanol fuel additive of the present invention have employed a kind of raw material of n-octyl amine.N-octyl amine (n-Octylamine), has another name called 1-amino-octane; Octyl primary amine; 1-octylame, molecular structural formula is:
N-octyl amine has a polar group amido (-N) and a non-polar group alkyl (-R).Polar group-N in n-octyl amine can be connected with the polar group hydroxyl (-OH) of multiple methyl alcohol, and a non-polar group alkyl (-R) in a n-octyl amine due to its group chain longer, can connect the alkyl (-R) in more gasoline or component oil, thus consumption is less.The present invention selects n-octyl amine to make solubility promoter, and its solubilization-aid effect is good especially, is innovative point of the present invention.Meanwhile, n-octyl amine has again the effect of metal protection, is also a kind of good auxiliary agent of rubber, has provide protection to rubber.Thus the single compound selected in the present invention can reach the effect of numerous additive in conventional methanol gasoline technology, and avoids the interference and contradiction that produce owing to using numerous additive, avoids the infringement to vehicle.
Additive of the present invention, under the prerequisite identical with the combustion-supporting effect that prior art reaches, consumption is only 0.05% ~ 0.8%, less than 1/10th of usual methanol gasoline dope, very efficiently.Although 2 ~ 3 times of additive price of the present invention normally usual methanol gasoline dope, due to the significantly minimizing of usage quantity, so cost also significantly reduces.
Beneficial effect of the present invention:
Expand the amount ranges of methyl alcohol, the capability of antidetonance is good, and combustion cleaning performance is good, and better, dynamic performance is good for low-temperature operability and cold starting performance, and corrosion-free and swelling action; Although additive types is single, but achieve beyond thought effect, when combustion efficacy is identical, both reduced additive amount, and decreased additive types, saved the energy, reduced production cost; Turn avoid methanol fuel to metal protection and the problem to swell rubber effect, further avoid the other technologies problem caused because of methanol fuel complicated component.The alternative gasoline of spark ignition engine methanol fuel of the present invention uses, such as adopting the automobile of spark ignition engine.As a kind of clean fuel, methanol fuel of the present invention can improve vehicle exhaust, reduces CxHy, NOx, SO in vehicle exhaust
2and CO content, be conducive to environmental protection.
