Description
Technical field
The invention belongs to new energy chemical technology fields, and in particular to a kind of Vehicular methanol petrol multiple-effect combined additive and
Preparation method.
Background technique
Methanol gasoline refers to national standard gasoline and methanol by certain volume (quality) than a kind of novel environment friendly made of allotment
Fuel can be used as vehicle fuel, become the substitute of gasoline.
The methanol gasoline capability of antidetonance is good, and the toxicity for the effluent that burns is smaller than regular gasoline, carbon monoxide content in exhaust
It is less.Combustion cleaning is functional.But corrosivity of the general methanol gasoline to petrol engine and the swelling to rubber material
Rate is all larger, and is easily delaminated, and low-temperature operability and cold starting performance are not as good as pure gasoline, as automobile-used in industrialization uses
Gasoline substitute still has following deficiency:
1) corrosivity: formaldehyde, formic acid, a large amount of vapor, unburned methanol for being generated in methanol and methanol combustion process etc.
Be corrosive to metal surface, cause the abrasion of parts around combustion chamber, as gas inlet outlet valve base, inlet and exhaust valve, valve guide bushing,
Piston ring, cylinder sleeve etc..
2) swellability: methanol is a kind of good polar solvent, they have not elastic gel, the sealing element etc. of engine
With the swelling action of degree.
3) cold start-up is difficult: the initial boiling point of methanol is higher than gasoline, and the latent heat of vaporization of methanol is gasoline more than 2 times, and methanol exists
Vaporization is to absorb a large amount of heat in admission line, reduces intake manifold temperature, causes methyl alcohol vaporizing difficult, and mixed air temperature
Spend it is very low, into cylinder after cause cylinder temperature very low, and methyl alcohol vaporizing amount is few, and especially winter is difficult to starting of catching fire.
4) Unregulated emissions are high: generating the compounds such as formaldehyde, formic acid as unconventional row during methanol combustion reaction
The pollutant put is more than gasoline combustion discharge amount, but can achieve exhaust emission standard after being handled with special-purpose catalyst and want
It asks.
5) intersolubility of pure and mild gasoline is poor, and there are laminations: when especially containing a small amount of moisture, lamination is more tight
Weight.
6) melt water of methanol gasoline: methanol polarity is very strong, can be with infinitely dissolve, stabilization of the moisture to methanol gasoline with water
Property influence it is very big, cause the methanol gasoline of stable uniform to be layered again.
7) high temperature of methanol gasoline is gas barrier: petroleum pipeline makes fuel evaporation generate bubble, especially summer because of high temperature, blocks up
Plug oil circuit causes engine to run out of oil and stop working.The vehicle that latent oil oil pump feed can only be used, substantially improves the problem of oil gas hinders.
8) with oily habit problem: at present because in the market methanol gasoline it is seldom or some it is local do not see, user vehicle
Methanol gasoline performance parameter is not known about, exists and uses oily habit problem, the market sales volume is affected, and high-end vehicles are reluctant to make
With main users concentrate on low and middle-end vehicle, and methanol gasoline economic benefit is general.
