Description
Technical field
The invention belongs to technical field of methanol fuel, relate to a kind of Vehicular methanol petrol, particularly a kind of a high proportion of Vehicular methanol petrol.
Background technology
The world energy sources reserves are shortage increasingly, and environmental problem is day by day serious, and energy problem and environmental problem have caused the great attention of countries in the world, and therefore, seeking new cleaning substitute energy has become global problem.The positive high speed development of China's economy, automobile pollution is more than 7,000 ten thousand at present, and the annual oil major part that consumes needs import.The energy and environmental problem are restricting the fast development of China's economy.
Light-duty vehicle fuel is always take gasoline as main, and still, this use pattern more and more is subject to environmental pollution and resource restriction day by day in short supply.In order to improve this predicament, the international and domestic various energy resources replacement scheme that adopted, such as gas fuel, alcohol fuel etc., if but these replacement schemes are wanted large-scale promotion, all exist serious defective.Good alternative fuel need to satisfy following requirement: 1, aboundresources, and price is suitable, can satisfy the needs of large-scale promotion; 2, fuel value, especially heat vale of mixture can satisfy the requirement of combustion engine powered performance; 3, be conducive to reduce the discharging of objectionable impurities; 4, can satisfy the requirement of the aspects such as vehicle launch performance, rideability and acceleration characteristics; 5, energy density is higher, the storage convenient transportation; 6, do not need to change engine, technical feasible; 7, existing fuel handling distribution system energy usefulness is upper.
Methyl alcohol can satisfy the requirement of above-mentioned condition fully as a kind of good substitute energy, has the advantages such as wide material sources, oxygen level is high, octane value is high, environmental pollution is little, is desirable motor spirit substitute.And the Energy Situation of the rich coal of China, few oil also provides the wide market space for implementing coal methyl alcohol processed as energy product, thereby methanol gasoline gets more and more people's extensive concerning as vehicle fuel in recent years.
The methanol gasoline of using at present mainly is that methanol content is mixed the burning methanol gasoline in 10～30% low ratio, and the substitution rate of the energy is not high, major portion or gasoline.Low ratio methanol gasoline exists also in extension process that a serious problem---saturated vapor pressure is high, oiling machine easily occurs at hot weather and add problem not fuel-displaced and automobile " breathing heavily ", this problem is seriously restricting low ratio methanol gasoline particularly popularization of southern area in the whole nation.
The problem that although gasoline of high proportion methanol does not exist above-mentioned " vapour lock ", present gasoline of high proportion methanol need to be changed engine when using, and user's input ratio is larger, is unfavorable for large-scale promotion.The problem that gasoline of high proportion methanol exists also is included in north cold start-up in winter difficulty, and-25 ℃ can't start substantially; Meet aqueous phase separation when use rainy season in south, affect automobile and use; Life-time service corrosion engine and fuel transfer system.
Summary of the invention
The purpose of this invention is to provide a kind of direct high-proportion methanol gasoline for vehicle, overcome the technical problem that gasoline of high proportion methanol exists at present in the situation that need not to reequip available engine, make gasoline of high proportion methanol can be good at being applied to vehicle.
Methanol quality mark in the direct high-proportion methanol gasoline for vehicle of the present invention is not less than 70%, and its constitutive material by following mass percent is formulated:
Methyl alcohol 70～90% component oils 7～29% additives 1～3%;
Wherein, described component oil is comprised of the component of following mass percent:
Saturated alkane 5～50% solvent oils 17～40% of C5～C7
90# gasoline 4～52% toluene 3～20%
In the above-mentioned raw materials, the saturated alkane of described C5～C7 is one or more the arbitrary proportion mixture in pentane, hexane, heptane, the 2-methylbutane, and described solvent oil is the arbitrary proportion mixture of 120# solvent oil and 200# solvent oil.
Described additive has the effects such as the burn into of inhibition stabilising system, enhancing power, and its component by following mass percent forms:
The monohydroxy-alcohol 48～92% of C3～C8
The sherwood oil 6～50% that boiling range is 30～60 ℃
Trimethyl borate 0～0.5%
Zinc peroxide 0～0.25%
Potassium permanganate 0～0.25%
Ethylene glycol monomethyl ether 0.5～4%
N, N '-two inferior bigcatkin willow-1,2 propylene diamine 0.05～1%.
Further, the monohydroxy-alcohol of described C3～C8 is one or more the arbitrary proportion mixture in Pentyl alcohol, the trimethyl carbinol, propyl carbinol, secondary octanol, Virahol, primary isoamyl alcohol, the n-Octanol.
Use the direct Vehicular methanol petrol of M85 of the present invention's preparation to carry out the car load platform experiment, by experimental data as can be known: directly automobile-used M 85 methanol gasoline and 93# GB steam oil ratio (SOR), power does not descend, 0～80 km/hour pick-up period is suitable with 93# GB gasoline.
Aspect emission behavior, along with increasing of methanol content, reduce 70% when CO, CH compound are than use gasoline in the exhaust emissions.The economy aspect, consumption run is the result show, uses that the car Santana fuel consumption per hundred kilometers is 10.32 liters under the direct Vehicular methanol petrol state of cyclic operation of M85 of the present invention, than 20 yuan of 93# GB gasoline cost savings.
Compare with other M85 methanol gasolines, the direct cold start of automotive methanol gasoline performance of M85 of the present invention is good, can normally start by 1～3 motor at subzero 25 ℃ of car Santanas.
With GB 93# steam oil ratio (SOR), the alternative ratio of the direct Vehicular methanol petrol of M85 is 1: 1.27, the alternative ratio of other M85 methanol gasolines is 1: 1.5, therefore, direct high-proportion methanol gasoline for vehicle specific consumption of the present invention is low, good economy performance compares with other M85 methanol gasolines, and hundred kilometers expenses can reduce by 8～12 yuan.
