Background technology
Because Taiwan lacks from main source of energy, up to being dependent on external import more than ninety percent, day by day exhausted when oil sources, the situation of fighting for the energy in the world will be more fierce, force oil price surging, Taiwan is necessary to research and develop voluntarily up-to-date technology, produce the mass-energy source, not only help, also can activate the farmland that large tracts of land is lain fallow in the ratio that improves the self-produced energy, for the rural area, Taiwan creates employment opportunities, start the new energy industry economy in Taiwan.
In the various renewable sources of energy, giving birth to the mass-energy source is the future source of energy new trend, and soybean, sunflower, sweet Potato are precious, the usefulness that can be used to refine biodiesel, ethanol blended gasoline.Biodiesel is extract by waste edible oil and soybean, sunflower and rape equal energy source crop, and energy crop absorbing carbon dioxide in growth course, row photosynthesis, the seed oil expression is after be converted into biodiesel, discharge carbon dioxide again after the burning, carry out " carbon cycle ", therefore be regarded as the renewable sources of energy, the carbon-dioxide emission that it causes can be considered zero, and also unlikely acceleration global climate warms up.According to foreign experience, biodiesel can be directly as the alternative fuel of diesel oil, or mix in varing proportions and fit in the commercially available diesel oil.The biodiesel of U.S.'s use at present is based on oleum sojae, and Europe is rapeseed oil.For example Germany is domestic, has 1,900 petrol service station that the oiling service of biodiesel is arranged at present, is to develop the most successful country of biodiesel in the world.
Though biodiesel has many advantages, but the raw material of biodiesel is from the triglyceride in the animals and plants, the unsaturated content of oil fatty acid is healed when high, its solidfying point is lower, vegetal oleum sojae and bird rape seed oil (mustard caul-fat) are higher because of the content of unsaturated fatty acid, so its solidfying point is lower, at room temperature be to exist with liquid state, be converted into (being biodiesel) behind the fatty acid methyl ester, to become the lower liquid of solidfying point, wherein the biodiesel solidfying point that changes into of bird rape seed oil can reach subzero 3-5 degree, and the solidfying point of the biodiesel of oleum sojae also can reach zero degree; It is less with part vegetable oil such as palmitic unsaturated fatty acid content to review animal, so be solid at low temperatures, be converted into fatty acid methyl ester, its solidfying point is between the 10-18 degree, if use the winter below temperature 10 degree, regular meeting has the phenomenon of solidification and crystallization to take place; With regard to reclaiming cooking oil, except that the processing of part vegetarian product is adopted the vegetable oil based on oleum sojae with oil, the comfortable processing fried or shortening of most recovery cooking oil is used oily, in order to reach specific local flavor or with the purpose of food embrittlement, usually all be mixed with low undersaturated animal oil or palm oil by the undersaturated vegetable oil of height, the solidfying point of the biodiesel of institute's output is situated between between the 3-10 degree usually.Though the part biodiesel is liquid state at normal temperatures, but the words of using in severe winter or some country situation of low temperature all the year round, oil product has the phenomenon of solidification and crystallization, and therefore the use for biodiesel is undoubtedly a kind of obstruction.
Comprehensively above-mentioned, therefore need a kind of fuel preheating device badly, not transforming under the situation of vehicle structure, can keep the oil product temperature again, to solve the biodiesel coagulation problem.
The specific embodiment
For making your juror further cognitive and understanding be arranged to feature of the present invention, purpose and function, hereinafter special relevant thin bilge construction and design-calculated theory reason with device of the present invention describes, so that the juror can understand characteristics of the present invention, detailed description is presented below:
See also shown in Figure 1ly, described figure is a fuel management method preferred embodiment schematic flow sheet of the present invention.Described fuel management method 3 is to include the following step: a characteristic information that at first carries out the fuel in the fuel tank at least one vehicle of step 30 monitoring.Described step 30 is to single car or a fleet, for example: haul truck-fleet, visit fleet, the characteristic information of the fuel in its fuel tank is monitored, the characteristic information of monitoring comprise promising fuel temperature, fuel acids base number, fuel quantity, oiling number of times, various chemical concentrations and aforesaid composition one of them.Described fuel may be selected to be biodiesel or diesel oil.Be biodiesel in the present embodiment.Wherein, the make a living concentration of matter diesel fuel composition of described various chemical concentrations (for example: fatty acid methyl ester), the concentration of glycerine, methyl alcohol, normal hexane or antioxidant includes free fatty acid, fatty acid ester.
Then carry out step 31, rely on a type of transmission to transfer to control center in described characteristic information.Can include the following step as for type of transmission: described characteristic information is transferred to control desk on the vehicle; And by described control desk transfer to described in the control center.Described console transfer to described in the mode at control center be may be selected to be global positioning system (GPS), whole packet radio (GPRS), WLAN (WLAN) and radio frequency identification communication (RFID) one of them.Wherein said control desk be may be selected to be a mobile phone, a PDA(Personal Digital Assistant) and micro computer one of them.Described middle control center then can be arranged on long-range, for example operate general headquarters or each operation branch etc.
