Description
Technical field
The present invention relates to a kind of fuel dope, particularly the additive of M50 carbinol gasoline fuel.
Background technology
Methanol fuel is used on petrol motor, the low ratio that accounts for 15% (M15) from methanol content is mixed burning, what the methanol content that develops into gradually the later stage eighties 20th century accounted for 85-100% (M85～M100) mixes burning at high proportion, has also experienced a quite difficult process.Along with the restriction of the factors such as the universal of automobile is on the rise with oil shortage, and processed oil price significantly goes up, and environmental protection pressure is increasing, research and development oil substitutes becomes one of focus in recent years.
Because methanol fuel physicochemical property approaches gasoline, on petrol motor, use methanol fuel, engine does not need to do large change, and methyl alcohol is that liquid is convenient to product conveying in addition, even if the conveying of longer distance is also convenient than defeated coal and gas transmission, is good gasoline substitute.Methyl alcohol while using as fuel, have splendid cooling effect, high antiknock ability and burning thoroughly, the advantage such as volatility is low, can reduce engine temperature, unlikely overheated, can be at the combusting under pressure of allowing higher than premium and can pinking, this is just being applicable to high compression ratio, high performance engine needs, and the obnoxious flavoures such as hydrocarbon polymer, nitrogen oxide and carbon monoxide that discharge after burning are few.As fuel, mainly there is following problem in current single methyl alcohol: the one, and pure methyl alcohol vaporization heat is higher, be 1178 KJ (kilojoule)/kilogram, and gasoline be only 330-420 KJ (kilojoule)/kilogram, under adiabatic 122 ℃ of conditions, can cool off, when evaporation, the reduction of mixture temperature is greater than gasoline.
M50 methanol gasoline, as the term suggests the gasoline mixed system that the methyl alcohol that the volume content of take is exactly 45-50% and volume content are 50-55%, cause automobile starting more difficult, and methyl alcohol has certain corrosion to automotive engine component, particularly make reduce the work-ing life of oil pump; The 3rd, current additive can not guarantee that the mutual solubility of gasoline and methyl alcohol is poor effectively, causes gasoline and methyl alcohol demixing phenomenon, makes the problems such as automobile cannot normally use.How to address the above problem is the Main Bottleneck of methyl alcohol replacing gasoline.
Summary of the invention
Order of the present invention is the defect that overcomes prior art, provides a kind of
The present invention is achieved through the following technical solutions: a kind of additive of M50 carbinol gasoline fuel, the volume ratio that comprises methyl alcohol and gasoline is the methanol gasoline of 45-50: 50-55, it is characterized in that adding in above-mentioned methanol gasoline the additive that cumulative volume is 2-5%, additive be by volume percent be respectively 60-70% by alcohols, alcohol ethers, the mutual solvent of the composite composition of arbitrary proportion of ester class and acetone, 24.4-30% by fat hydrocarbon, the detonator of the composite composition of arbitrary proportion of arene and methyl tertiary butyl ether, the composite ignition dope forming of the arbitrary proportion by nitro class and nitrate esters of 4-6%, 1-3% is by phenols and the composite corrosion inhibitor forming of grease arbitrary proportion and appropriate catalyzer, antioxidant stabilizer forms.
Above-mentioned catalyzer be 4-anisole sulfonyl hydrazide Ben Jia Xian ? toluene solution, the mass percent concentration of this solution is 5%, this catalyzer accounts for the 0.5-1% of above-mentioned additive cumulative volume.
Phenols in above-mentioned corrosion inhibitor is 2,4 diisopropyl phenols or 2,4 di-tert-butylphenols.
Above-mentioned antioxidant stabilizer is the tetrahydrofuran solution of 5-alkoxyl group-2 (5H) furanone, and the mass percent concentration of this solution is 5%.
Alcohols in upper mutual solvent is isopropylcarbinol, secondary octanol, and alcohol ethers is ethylene glycol ethyl ether, butyl glycol ether, and ester class is ethyl acetate, acetic acid isoamyl fat.
Fat hydrocarbon in above-mentioned detonator is that sherwood oil, arene are that toluene, dimethylbenzene, ethers are methyl tertiary butyl ether.
Nitro class in above-mentioned ignition dope is oil of mirbane, nitrotoluene, and nitrate esters is isoamyl nitrate, isobutyl nitrate, isooctyl ester nitrate.
Mass percent >=99% of above-mentioned methyl alcohol.
Feature of the present invention and effect: 1, in M50 methanol gasoline, add after additive of the present invention, its methanol gasoline has good mutual solubility, system homogeneous, transparent, low temperature thing are without being separated.2, startability is good, is not subject to seasonal effect.3, good dynamic property, substitutes than high.Although the calorific value of methyl alcohol is lower one times than gasoline, the methanol gasoline under this ratio, after adding additive of the present invention, the fuel oil consumption carrying out with pure gasoline in the experiment of vehicle road conditions is compared, and alternative ratio is 1: 1.1-1.2, good economy performance.This additive is containing a huge sum of money Element Lead, manganese simultaneously, also sulfur-bearing not, and phosphorus, halogen families etc. are the element to environment in combustion processes.4, in M50 methanol gasoline, add after additive of the present invention, the oil pump of automobile reaches more than 3000 hours work-ing life, substantially engine is not had to detrimentally affect.5, additive of the present invention have easy to use, raw material sources are extensive, production technique is simple, be convenient to the features such as popularization, solved defect of the prior art and existing issue.
