Description

The additive of M30 carbinol gasoline fuel

Technical field

The present invention relates to a kind of fuel dope, particularly the additive of M30 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, the methanol content that develops into gradually the later stage eighties 20th century accounts for 85-100%(M85-M100) mix at high proportion burning, 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 the processed oil price significantly goes up, and environmental protection pressure is increasing, the research and development oil substitutes becomes one of focus in recent years.

Because the methanol fuel physicochemical property approaches gasoline, use methanol fuel on petrol motor, engine does not need to do large change, and methyl alcohol is that liquid is convenient to the product conveying in addition, even the conveying of longer distance, also than defeated coal and gas transmission facility, is good gasoline substitute.Methyl alcohol when acting as a fuel and using, 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 just is 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.Current single methyl alcohol acts as a fuel and mainly has following problem: the one, and pure methyl alcohol vaporization heat is higher, it is 1178 KJ (kilojoule)/kilogram, and gasoline is 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.

The M30 methanol gasoline, as the term suggests the gasoline mixed system that the methyl alcohol that the volume content of take exactly is 30% left and right and volume content are 70% left and right, because the existence of methyl alcohol causes cold-starting automobile more difficult, and methyl alcohol has certain corrosion to automotive engine component, particularly make reduce the work-ing life of oil pump, and 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 can't 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 M30 carbinol gasoline fuel, comprise the M30 methanol gasoline, it is characterized in that in above-mentioned methanol gasoline adding the additive that cumulative volume is 2-5%, additive be by volume percent be respectively 50-60% by alcohols, the alcohol ethers, the solubility promoter of the composite composition of arbitrary proportion of ester class, 30-40% by fat hydrocarbon, the detonator of the composite composition of arbitrary proportion of arene and methyl tertiary butyl ether, the composite ignition dope formed of 4-6% the arbitrary proportion by nitro class and nitrate esters, 1-4% by phenols and the composite corrosion inhibitor formed of grease arbitrary proportion and appropriate catalyzer, antioxidant stabilizer forms.
