Beneficial effect experiment:
1, the octane value of ether-base gasoline experiment, the octane value after the gasoline of ether-base gasoline of the present invention and the different trades mark is composite sees table 1:
Table 1: the composite octane value of different ratios is as following table:
2, high temperature resistance vapour locking technology, the method for inspection: GB/T8017.
Saturated vapor pressure is the index that directly affects automobile and whether produce vapour lock, and for example, if when vehicle saturated vapor pressure is excessive, summer (1-September 30 May), saturated vapor pressure reached 74kpa, will produce vapour lock, vehicle can not normally use; Table 2 is the value of different ratios ether-base gasoline and vapour pressure.
Table 2: different ratios ether-base gasoline saturated vapor pressure
Consolidated statement 2 can be found out, even the saturated vapor pressure of (40 DEG C) ether-base gasoline also meets the standard that country is used gasoline under extreme temperature, ether-base gasoline can use completely, passing ratio pairing, can find out that ether-base gasoline and gasoline are composite, not affect vehicle and use.
3, the detection of existent gum, the method for inspection: GB/T8019
Existent gum is the important index that gasoline uses, if more than the colloid of gasoline reaches 20mg/100ml, automobile will break down with regard to engine in the distance of the 800km that travels so, existent gum is excessive is the major reason that engine breaks down.Following table 3 is detected results of ether-base gasoline colloid.
Table 3: the detected result of ether-base gasoline colloid
Comprehensively form 3 can be found out, ether-base gasoline colloid is little, when ether-base gasoline and the composite use of gasoline, can reduce the colloid of original gasoline, and this index of ether-base gasoline colloid also meets gasoline and uses standard, and ether-base gasoline can not impact car.
4, anti-corrosion effects detects
Ether-base gasoline is good erosion resistance, and having solved methyl alcohol has swelling action to some rubber, plastic component, affects the use properties of material; It is strong that ether-base gasoline has overcome methyl alcohol polarity, electric conductivity is high, corroding metal, solve the effect that methyl alcohol absorbs airborne moisture and oxygen and produced a small amount of organic acid, and combustion processes also produces the acidic substance such as a small amount of formaldehyde, formic acid, cause the etching problem of some accessory (fuel tank, oil pipe, oil pump etc.) of automobile.Following table 4 is the nonmetal soak test result of part engine fuel system.
Table 4: part engine fuel system nonmetal parts soak test
Can find out by above-mentioned Experimental Comparison, the overall swelling property of ether-base gasoline is more effective than methanol gasoline M20's, all more effective than gasoline to stearic urethanes, polypropylene, soft polychlorostyrene alkene, rubber-asbestos plate, rubber unvulcanizate, the swelling effect of folder cloth oil resisting rubber with gasoline contrast ether-base gasoline; Contrast by swelling property, the swelling not impact of the rubber seal of ether-base gasoline on car, can normally be used.
5, dynamic property experiment
The calorific value of ether-base gasoline is 21.9MJ/kg, is 45% of gasoline, in gasoline, mix 15% ether can cause propellant combination calorific value reduce, make power decline, oil consumption increase.According to law of conservation of energy, Optimization additive of the present invention, high heating value oil of mirbane and ether compound and ester compound are matched, and add trace catalyst and purification agent, utilize the Catalysis Principles of purification agent and catalyzer to improve calorific value, automobile " ignition advance angle " is appropriately adjusted again, prove through vehicle test many times, dynamic property is without considerable change simultaneously.Ether-base gasoline is 1.02:1 with the alternative ratio of GB gasoline.
Table 5 is the calorific value of different ratios ether-base gasoline propellant combination
[0035]6, cold-starting experiment
Through experiment, ether-base gasoline can improve the volatility of propellant combination, reaches the flammable limit of gas mixture, realizes the cold start-up under low temperature (10～30 DEG C), and improves the octane value of fuel; Therefore it is poor that ether-base gasoline has solved methanol gasoline vapo(u)rability in the time of low temperature, and the latent heat of vaporization is large, further reduces air flue temperature, especially (10～30 DEG C) cold start-up difficult problem under severe cold condition when evaporation.
7, driving experiment
1) condition: white Jetta car, the 150000 kilometers of not cleanings of driving a vehicle; Travel has turning, the highway of upward slope and descending; Road speed is at 20km/h-160km/h, under Air conditioned condition; At 33 DEG C of temperature.Experimental result is in table 6: the ether-base gasoline running data of different ratios.

By finding for experiment of table 6, add the gasoline of ether-base gasoline, vehicle in the process of moving, is all saved with oil.Can find out by experiment, in gasoline, configure the ether-base gasoline better effects if of 15%-20%.
2) condition: the A6 of black Audi, the 100000 kilometers of not cleanings of driving a vehicle; Travel has bend, the highway of upward slope and descending; Road speed is at 20km/h-160km/h, under Air conditioned condition; At 33 DEG C of temperature.Experimental result is in table 7: the ether-base gasoline running data of different ratios.
Table 7, the ether-base gasoline running data of different ratios
By finding for experiment of table 7, add the gasoline of ether-base gasoline, vehicle in the process of moving, is all saved with oil.Can find out by experiment, in gasoline, configure the ether-base gasoline better effects if of 15%-20%.
8, fuel-economizing experiment
Detect through experiment, the amount of different vehicle fuel-economizing sees table 8:
Table 8: the amount of different vehicle fuel-economizing
Can find out ether-base gasoline and the composite use of the gasoline generally fuel-economizing of automobile for market by table 8, use range all can reach oil-saving effect between 5%-20%.
Known through experimental result, the present invention has following beneficial effect:
(1) octane value is high, and anti-knocking property are good.Ether-base fuel octane value, than with the high 3-5 of a trade mark GB leadless gasoline octane rating unit, is applicable to high compression engine, and anti-knocking property are good.
(2) wide material sources, with low cost.The raw material that ether-base fuel uses is all from China's Coal Chemical Industry product, thereby cost is only the 60-70% of China's regular gasoline, ethanol petrol, methanol gasoline.
(3) high detergency, high-environmental.Because burning is complete, ether-base fuel makes the content of auto-pollution discharge reduce 30-50%, can effectively remove vehicle fuel feeding simultaneously, the work-ing life of firing system carbon distribution, prolongation engine.
(4) versatility is good.In the situation that not changing engine structure and parameter, any a motor car engine all can directly be used ether-base fuel.
(5) dynamic property is stronger.Ether-base fuel is in layoutprocedure, and composite multiple additives, has increased its homogeneity and combustion stability, has strengthened engine power performance simultaneously.
(6) long quality-guarantee period.The existent gum of ether-base fuel is 1/5th of the Europe IV standard, and be the more than four times of Europe IV and GB gasoline inductive phase, can steady in a long-term preserve, and has extended the time of storage, transport, use.
(7) both miscible burning of mixing, can be used alone again.Ether-base fuel solved methanol gasoline substitute than the global problem low, ethanol petrol is short of power, can be used alone, also can with the regular gasoline miscible burning of mixing in any proportion.
(8) ether-base gasoline production cost 4000-4500 yuan/ton, market price 6300-6500 yuan/ton, with the price difference of existing 93# gasoline (9500 yuan/ton) be 3000 yuan/ton, therefore can be significantly cost-saving.
Obviously, the above embodiment of the present invention is only for example of the present invention is clearly described, and is not the restriction to embodiments of the present invention.For those of ordinary skill in the field, stating on bright basis and can also make other changes in different forms.Here cannot give exhaustive to all embodiments.Everyly belong to apparent variation or the still row in protection scope of the present invention of variation that technical scheme of the present invention extends out.
