Description
The present invention relates to the purposes of alcohol in fuels for spark ignition engines, and relate to the preparation of fuels for spark ignition engines.Except ethanol, these fuel also comprise C
4Alcohol.
Fuels for spark ignition engines is the motor spirit that is applicable to spark ignition engine.They comprise the mixture of the different hydrocarbon with different boiling usually, and the described boiling point under the normal atmosphere is usually in 26 ℃ to 210 ℃ scope.Yet this scope is not clear and definite predetermined, and can be depending on the actual composition of hydrocarbon, additive and other component, and depends on envrionment conditions.Usually, the hydrocarbon component of fuel comprises C
4-C
10Hydrocarbon.
The requirement that must reach in the spark ignition fuel fabrication is many-sided.They are results of rules, distribution chain and their application in engine.In addition to these, prepare actual conditions and different transmission designs in addition, this need be divided into spark ignition fuel different types.In Germany, implement minimum requirements with the form of DIN Standards (DIN standard) according to decree.In the service station, they must be identified with suitable sign.Proposed and now only allow to satisfy the fuel of all DIN Standard EN228 requirements at 2004 and the Fuel Quality Decree (fuel mass decree) that upgraded in 2006 in 1993.In the U.S., apply corresponding standard according to ASTM 4814.
In order to reach best transmission condition, fuel should satisfy the various different requirements of vehicle.Under particular case, this is meant: after the long night of experience cold, engine should be easy to start as summer; That is to say, as stopping the obviously engine restart of heating of back between of short duration.And when idle running, engine should not stop working; And under high capacity, should not become unstable.Even under disadvantageous condition, the interference resistates does not have in inlet system, combustion chamber or the oil groove yet.
Fuel should adapt to these different and partly requirements of contradiction in some way, so that trouble free, reliable and mutually beneficial interaction become possibility.Therefore, German brand manufacturer is blended into the material that is called as " mineral oil alternative compositions " of limited proportion such as the chemically reactive substance of pure and mild ether and maximum 0.5 weight % in the basic fuel.
To being used for being called as the fuel of propellant combination vehicle, stipulated to have the specific requirement of 0 volume % to 85 volume % alcoholic acid alcohol content.For 70 volume % to the 85 volume % alcoholic acid fuel that have that are called as E85, the vapour pressure of cold start-up mode is especially crucial.It is known having the pure fuel as ethanol or different alcohol mixtures of high-content.Patent application HK 106 428, US2006/0137243, US 2004/0107634 and US 2004/123518 have mentioned these by way of example.
Also known, make typical purified " super white gasoline " or research octane number (RON) (also being called as RON) be summer of 95 or winter quality gasoline mix with the bio-ethanol of 70 volume % or 85 volume %.According to draft specifies CWA 15293 and 51625 (in the October, 2007 of Draft Standard E DIN of in May, 2005 CEN Workshop Agreement, Beuth Verlag) suggestion, the minimum vapour pressure in summer is 35kPa (an A level), and the minimum vapour pressure in winter is 50kPa (a B level).According to the vapour pressure of super white gasoline in basis or Fuel Petroleum, the vapour pressure of gasoline/alcohol mixture may not meet draft specifies.In these cases, must be with the downward modulation of the alcohol concn in the mixture, this is worthless.
Therefore, the object of the present invention is to provide the fuel with high density alcohol, described fuel quantity ga(u)ge reveals sufficiently high vapour pressure, and for example pressure can satisfy regulation.This is intended to strengthen cold starting performance, even for example to guarantee that in the winter time fuel also can show good cold starting performance under the temperature.
By using the C of at least a claim 1
4Alcohol has solved this problem.
Basic fuel is a regular price gasoline, and white gasoline for example, the RON that provides as Germany and European elsewhere are 95 white gasoline.
Since 1984, provide as Normal (standard level) in the service station, provided to be used as Euro-Super (European superelevation level) from 1985 in addition, and from be specified in European Standard DIN EN 228 in 1993 in 1989 with the minimum standard that is used as the white gasoline that SuperPlus (reinforced superelevation level) provides in.The composition that derives from the spark ignition fuel of German refinery with standard level, superelevation level and reinforced superelevation level quality is found in for example German ScientificAssociation for Mineral Oil, Na tural Gas is among the DGMK Research Report 502-1 of and Coals (being also referred to as DGMK).In this is analyzed, measured the main ingredient of fuel, specifically, measured described main ingredient in the mode of mean value and scope.The foundation of this analysis is the product in winter in 2001/2002 winter.This paper is clearly with reference to this report.Specifically, 50 kinds of content have been measured with the hydrocarbon of 3 to 6 carbon atoms, 51 kinds of aromatic hydrocarbons and 3 kinds of oxygenatedchemicalss.In addition, for all paraffin, naphthenic hydrocarbon, cycloolefin and non-ring olefin and aromatic hydrocarbons, measured the total content that has all representatives of same carbon content under every kind of situation.What measure separately is the content of 10 kinds of diene and 15 kinds of polycyclic aromatic hydrocarbonss.Related spark ignition fuel is derived from 14 kinds of different raffinates.
Gained fuel of the present invention comprises this type of basic fuel of 15 volume % to 50 volume %.
The trend of gasoline volatilization (its volatility) is the primary prerequisite as spark ignition fuel, also is basic qualitative characteristics simultaneously.Because gasoline is the mixture of many hydrocarbon, so it does not have the boiling point of qualification, but has the boiling range between 30 ℃ to 200 ℃ usually.
Fuel of the present invention comprises the ethanol of 15 volume % to 65 volume % and the C of 15 volume % to 50 volume %
4Alcohol.Certainly, amount to, comprise any other component that may exist, always obtain the summation of 100 volume %.
In principle, with respect to normal fuel, the characteristic of fuel is owing to high-load alcohol changes.A kind of this class feature is a volatility for example.
Volatilely be characterised in that in most cases 30 ℃ to 200 ℃, the boiling curve in the wideest 26 ℃ to the 210 ℃ temperature bands, and volatile vapour pressure that is characterised in that.Boiling curve has been described the volatilization fluid proportional under the differing temps.Vapour pressure be fuel element under limiting temperature, in encloses container, be transformed into the result of vapor phase mutually from fluid.
" evaporable gasoline fraction/temperature " function provides alleged boiling curve, and its position makes those skilled in the art can draw and the relevant conclusion of fuel behavior in engine with characteristic.In principle, the volatility of spark ignition fuel must be determined in some way, makes to have the fuel-air mixture that can light in the combustion chamber in all cases.Under specific operational condition, the engine of for example cold especially or extreme heat, this prerequisite is difficult to satisfy, and makes the fuel quality difference to confirm according to this criterion.
The ignitionability of mixture not only is subjected to the influence of fuel, and is subjected to the influence of engine design.That is be aspect the driving of " richness " or " poor " mixture, to there are differences, at engine.
With regard to winter operation, the volatility of spark ignition fuel generally is suitable for cold envrionment temperature.In order to obtain reliable cold start-up, described fuel should volatilize as much as possible.To cause mixture owing to the insufficient and too much fuel of evaporation is condensate on the intake manifold wall and becomes poor because cross low volatility, so the startup and the preheating that help engine of the low boiling curve in the low temperature range and high-vapor-pressure.
To thermo-motor gasoline require just the opposite.Under disadvantageous condition, the variable constituents in the fuel system gets awfully hot, makes the fuel volatilization (in the oil fuel pump " formation vapor phase ") of ratio too much, and the vaporizer floating chamber is left in boiling, or forms steam cushion in injection system.Therefore, fuel is carried and is interrupted, and the excessive enrichment of mixture, and this has disadvantageous effect to transmission performance.These upset to occur frequent more, and it is just hot more that fuel system (pump, vaporizer and fuel injection system) becomes, and fuel delivered volume and system pressure are just low more.Aspect fuel, too high volatility makes and himself obviously causes disadvantageous effect.Summer environment high temperature has increased the possibility of fault.For this reason, the fuel making merchant mixes their summer variety in some way, makes that with respect to the winter fuel kind, boiling curve height and steam in the low temperature range force down.Yet this adjustment necessarily can not be excessive to cause cold start-up to produce difficulty.
According to basic fuel, especially have high-content alcoholic acid fuel mixture, can not keep the minimum vapour pressure that should keep usually according to draft specifies, especially winter product.The result is will have to reduce ethanol content to reach minimum vapour pressure.
Surprisingly, find, by comprising substrate gasoline and alcoholic acid fuel (for example E85) and at least a C
4Alcohol (for example can have high density C
4Other fuel form of alcohol exists) mix the raising that can realize the mixture vapour pressure, described vapour pressure is higher than the vapour pressure of independent fuel.In the laboratory, measured the vapour pressure (according to EN 13016-1) of various ethanol and butanols mixture in the super matter gasoline.
The results are shown in table 1 and 2.Be used under every kind of situation to characterize behind the character of independent combination numeral this make up the content of per-cent (%) meter by volume.
Fuel of the present invention has satisfied the requirement that above relates to, and has improved cold start characteristics specifically.
Can determine in principle, for the alcoholic acid mixture of basic fuel and higher proportion, if with at least a C
4Alcohol joins in this mixture, makes its content in the gained fuel mixture equal at least 15 volume %, and the atypia that vapour pressure then takes place increases.This increase of vapour pressure is that those skilled in the art are unpredictalbe.After mixing, comprise 15 volume % to 50 volume % basic fuels, 15 volume % to 65 volume % ethanol and 15 volume % to 50 volume %C
4In the fuel of alcohol, described effect is significant.After mixing, comprise 20 volume % to 46 volume % basic fuels, 20 volume % to 60 volume % ethanol and 20 volume % to 50 volume %C
4In the fuel of alcohol, and especially after mixing, comprise 19.5 volume % to 44 volume % basic fuels, 21 volume % to 59.5 volume % ethanol and 21 volume % to 49 volume %C
