ethanol, commonly known as alcohol, ethanol gasoline is one kind of new alternative energy and various food processing plant fibers into fuel ethanol and regular gasoline compounding formed by a certain percentage. According to the national standards, ethanol gasoline is blended with 90 percent and 10 percent of regular gasoline fuel ethanol.
1. Noun interpretation ethanol gasoline
ethanol, commonly known as alcohol, ethanol gasoline into a plant by a variety of food and fiber processing regular gasoline fuel ethanol and mixed is formed by a certain percentage the new alternative energy. According to the national standards, ethanol gasoline is blended with 90 percent and 10 percent of regular gasoline fuel ethanol.
2. Detailed ethanol gasoline
Ethanol can effectively improve the performance and quality of the oil, to reduce carbon monoxide, hydrocarbons and other major pollutants. It does not affect the car’s driving performance, but also reduce emissions of harmful gases. Ethanol gasoline as a new clean fuel, renewable energy is currently the world’s development priorities, in line with our strategy of alternative energy and renewable energy development, technically mature safe, reliable, fully applicable in our country, with good economic and social benefits. China’s first production of ethanol fuel companies Henan Nanyang days crown group, the national focus of pilot enterprises, the first pilot to ethanol fuel is also in Henan, Zhengzhou, Luoyang, Nanyang three.
now mainly based on sweet sorghum-based ethanol, sweet sorghum and low-input high-yield, all benefits and biomass greatest potential for development.
3. The basic description of ethanol gasoline
means a vehicle ethanol gasoline containing no methyl tertiary butyl ether (MTBE), specific oxygen-containing gasoline additive component of the oil , by adding a certain proportion of the volume ratio (percentage of tentatively 10) in denatured ethanol fuel, ethanol gasoline by the deployment center point according to the quality requirements of the national standard GB18351-2001, compounded by a specific process from generation clean environment car fuel.
ethanol gasoline research octane number divided by the number 90, 93, 95 three grades.
flag is raised before the gasoline reference letter E, indicated as a unified vehicle ethanol gasoline, gasoline grades are three kinds of sign “E90 gasohol No. 90”, “E90 gasohol 93 “,” E90 gasohol 95. ” Ethanol gasoline is suitable for all types of vehicles equipped ignition engines, no matter how large the carburetor or fuel injection lubrication method, medium and small vehicles. Disadvantage
4. Ethanol gasoline of
● thermal value of the ethanol conventional vehicle 60 percentage gasoline reportedly relevant information, if the car does not make any changes on the use of ethanol containing 10 when the percentage of the blended gasoline engine fuel consumption would have been five percentage.
● large latent heat of vaporization of ethanol, the evaporation temperature is greater than the stoichiometric air regular gasoline. The impact of the mixture formation and combustion rate, resulting in decline in automobile power performance, economy and cold start properties, is not conducive to the acceleration of the car.
● ethanol produced during the combustion of acetic acid, particularly copper corrosive to metal car. For tests showed that the ethanol content in gasoline at 10 ~ 0 percentage, substantially no corrosion of the metal, but when the alcohol content exceeds 15 percentage must add effective corrosion inhibitor.
● ethanol is a good solvent, prone to slight corrosion of the car seal rubber and other synthetic non-metallic materials, swelling, cracking, or softening effect.
● be inhaled ethanol in water, ethanol gasolineAfter the moisture content exceeds the standard indicators, liquid phase separation occurs readily.
