It can be said that E85 can be manufactured simply by blending ethanol with gasoline. (100% ethanol around 115/120 octane, E85 is around 100/105 octane and it drops quickly after that) It is suggested that 100 octane be used for E85 in this calculator to give a more accurate octane rating when mixed (diluted) with gasoline. Like all consumer products, there are pros and cons to using E85. However, E85 can further reduce emissions of certain pollutants as compared to conventional gasoline or lower-volume ethanol blends. Eric Kvaalen, Philip C. Wankat, Bruce A. McKenzie. Some In countries like Australia where E85 is always 85% ethanol (and pump fuel with varying fractions is called "flex fuel"), performance motoring enthusiasts and motor racing clubs/championships use E85 extensively (without the need for any FFV certification). It also aids Molecular Formula. However comparing energy expressed as a value of heat does not reflect the total work from an Otto Cycle[citation needed]. The pros include: Ethanol is an alcohol fuel derived from several different plant materials, including corn, sugar cane, or various grasses. [9], E85 critics contend that production of ethanol from corn (maize) drives up world food prices, causing corn to be unaffordable or even unavailable. Use of alcohol (ethanol and methanol) in motor racing history parallels the invention of the automobile, favoured due to inherent combustion characteristics such as high thermal efficiency, raised torque and with some advanced engines, better specific fuel consumption. Flex-fuel vehicles in Brazil run on E100 as opposed to the E85 that is for sale in most parts of the world. Fuel sold as E100 is always 100 percent ethanol, while fuel sold as E85 always contains 85 percent ethanol. It's less available in other regions, especially New England and the Pacific Northwest. Research by the U.S. Energy Information Administration shows that pure ethanol has a lower heating value than gasoline, so it makes it harder to start a car's engine in areas with a cold climate. According to the manufacturer, this is due to the cooling properties of ethanol. E85 critics contend that ethanol producers may not reduce carbon emissions due to the petroleum and natural gas used in raising corn and refining it. Stainless steel fuel lines, sometimes lined with plastic, and stainless-steel fuel tanks in place of terne fuel tanks have been used. E85 gas (also known as flex fuel) is a high-level combination of ethanol and gasoline that consists of 51 percent to 83 percent ethanol blended with gasoline. E85 advocates say that corn prices have increased due to manipulation of the commodities markets and because American corn companies sell more and more US-grown corn to Mexico and China, creating more competition for corn buyers, and therefore driving up its price. E85 gas is suitable for use in any vehicle designated as a flex-fuel vehicle by the manufacturer. Some vehicles can be converted to use E85 despite not being specifically built for it. Ethanol, C2H6O, is ethane with a hydrogen molecule substituted by a hydroxil radical. In contrast, ethanol critics contest the benefits of E85 by focusing on the fact that E85 has 33% lower heating value compared to the higher heating value of gasoline. The regular gasoline is made up of hydrocarbons with between 5-12 carbon Speculations relate that Other measures taken by Congress to jump start ethanol production include the 2004 VEETC bill, which provided for a Small Ethanol Producer Tax Credit which gave tax credits to small ethanol producers. They can run on anything from 100-percent gasoline to blends containing 85 percent ethanol. powder. The mixture or mash from the cookers is chilled so that the secondary enzyme can be mixed to let the liquified starch to dextrose or turn into fermentable sugars. Because energy content does not factor certain latent or specific heat values[citation needed], nor combustion pressure, so looking at heat alone in the combustion equation does not determine efficiency or work according to the laws of thermodynamics. [3] The production of ethanol, including E85, receives a lot of commendations especially when it was utilized as fuel to substitute [clarification needed] most in demand commodity in the country today. With regard to the efficiency of E85, calculations say that even though ethanol contains lesser energy than gasoline, E85 has higher All 2001-model standard vehicles and newer can run on E15 but can't handle the corrosiveness of higher ethanol percentages. Because E85 is predominantly ethanol, the exhaust emissions are very different from those of regular gasoline. Another component of E85 is gasoline or petroleum. Studies have shown that the utilization of ethanol fuel reduces air pollution and lessens the need for imported oil. The motor racing industry has always preferred ethanol- or methanol-based fuels because these fuels tend to give performance vehicles more thermal efficiency and increased torque. Producers add more ethanol in the summer as opposed to the winter. In Brazil, sugar cane is a prominent source of ethanol. Outside the United States, ethanol producers often use alternative crops. In the latest study, USDA states that the production of ethanol produces 34% more energy than what is utilized in planting and harvesting grains and purifying or distilling them into ethanol. E85 also has higher octane content, which can provide more engine power. SCHEMBL730334. It is colorless, flammable and a moderately toxic chemical compound that has a unique, perfume-like smell. Ethanol can be blended with gasoline to produce alternative transportation fuels like E85, a blend of 85% ethanol and 15% gasoline. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. It is a renewable resource that is produced domestically rather than imported. [citation needed], E85 promoters and the Society of Automotive Engineers contend that automotive manufacturers currently fail to equal the fuel consumption of gasoline because they fail to take advantages of characteristics which are superior in ethanol-based fuel blends.
