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 that utilizes fuel, changes the chemical energy of fuel into heat energy, and then heat energy is changed into the oil engine of mechanical energy by piston.Spark ignition engine can adopt methanol gasoline replacing gasoline as fuel.Methanol gasoline is in existing gasoline or gasoline component oil, to add the dissimilar additives 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 of using is different, and its effect of bringing and impact are also just variant.In the prior art, the add-on of methyl alcohol is 5%～20%, 15% in the majority to add; Advantage is that the capability of antidetonance is good, and combustion cleaning is functional, and shortcoming is to petrolic corrodibility and all larger to the swelling ratio of elastomeric material, and is easy to layering, and poor aspect 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 that methyl alcohol produces in combustion processes, formic acid, corrosion of metal problem has been added to metal protection agent, 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 adding can produce certain corrodibility and cause new problem metal again.Visible, methanol gasoline of the prior art is because the complicated problem causing of additive component is comparatively serious.
Methanol fuel is normally processed methyl alcohol and gasoline by solubility promoter, allow methyl alcohol and gasoline form uniform mixture, thereby burns generate energy propelling vehicle engine together with gasoline.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 composition that it is main is solubility promoter, and solubility promoter is low-carbon (LC) alcohols mostly, and price is higher, and the usage quantity in prior art scheme is very large, is generally the more than 3% of total inventory, causes production cost to improve.
Applicant, by constantly making great efforts and great many of experiments, has developed a kind of alternative gasoline, is suitable for the novel carbinol fuel that spark ignition engine is used.
Summary of the invention
The object of the present invention is to provide a kind of spark ignition engine methanol fuel, the additive component that solved methanol fuel in prior art is complicated and cause metal is corrosive, rubber is had the problems such as swelling action, solved 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 spark ignition engine methanol fuel, comprises methyl alcohol, additive, and gasoline or gasoline component oil, 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;
By each raw material according to the above-mentioned raw materials mixing and stirring of filling a prescription.
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%.
After mixing, described raw material stirs 20～60min.
The alkane that described gasoline component oil is C5～C12 for composition.
Spark ignition engine of the present invention is used for petrolic application with methanol fuel.
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 and need 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, thereby allow together with the methyl alcohol of polarity can mix by the anastomosis of solubility promoter with nonpolar gasoline, form uniform mixture.
It is raw material that the present invention adopts gasoline or gasoline component oil, and wherein, gasoline component oil is commercially available prod.Adopt gasoline or gasoline component oil all can, facilitate compounding methanol fuel, the use that is conducive to product is promoted.In the present invention, gasoline component oil adopts the alkane that composition is C5～C12, can obtain better effect.For more deficiency of supplementing petroleum resources, develop the simple and efficient high concentration methanol fuel of composition imperative.The present invention has expanded the usage quantity scope of methyl alcohol, and handiness is large and guaranteed result of use.
In order to solve methanol fuel because of problems such as the complicated metallic corrosion causing of additive component or swell rubber, creationary of methanol fuel additive of the present invention has adopted 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 a plurality of methyl alcohol, and a non-polar group alkyl (R) in a n-octyl amine is because its group chain is longer, can connect the alkyl (R) in more gasoline or component oil, thereby 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, and rubber is had to provide protection.Thereby the single compound of selecting in the present invention can reach the effect of numerous additives in traditional methanol gasoline technology, and avoided, due to interference and the contradiction of using numerous additives to produce, having avoided the infringement to vehicle.
Additive of the present invention, under the identical prerequisite of the combustion-supporting effect reaching with prior art, consumption is only 0.05%～0.8%, less than 1/10th of common methanol gasoline additive, very efficient.Although additive price of the present invention is 2～3 times of common methanol gasoline additive normally, due to the significantly minimizing of usage quantity, so cost also significantly reduces.
Beneficial effect of the present invention:
Expanded the amount ranges of methyl alcohol, the capability of antidetonance is good, and combustion cleaning performance is good, and low-temperature operability and cold starting performance are better, and dynamic performance is good, and corrosion-free and swelling action; Although additive types is single, but obtained beyond thought effect, in the situation that combustion efficacy is identical, both reduced additive amount, reduced additive types, saved the energy, reduced production cost; Avoid again methanol fuel to metal protection and the problem to swell rubber effect, further avoided the other technologies problem causing because of methanol fuel complicated component.Spark ignition engine of the present invention is used with the alternative gasoline of methanol fuel, such as for 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.
