According to Consumer Reports, "ethanol isn’t as energy-dense as regular gasoline so you will see worse fuel economy with E15 gas.” [67] In March 2009, a lobbying group from the ethanol industry, Growth Energy, formally requested the U.S. Environmental Protection Agency (EPA) to allow the ethanol content in gasoline to be increased from 10% ...
For each billion ethanol-equivalent gallons of fuel produced and combusted in the US, the combined climate-change and health costs are $469 million for gasoline, $472–952 million for corn ethanol depending on biorefinery heat source (natural gas, corn stover, or coal) and technology, but only $123–208 million for cellulosic ethanol ...
Typical label at the gas pumps warning drivers of ethanol content up to 10%, used as oxygenate additive instead of MTBE. Miami, Florida. In 1826 Samuel Morey experimented with an internal combustion chemical mixture that used ethanol (combined with turpentine and ambient air then vaporized) as fuel.
The government will raise the limit on ethanol concentration in gasoline for some cars. The Environmental Protection Agency will raise the limit to as much as 15%, from the current 10%, for ...
The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. Simple calculations of the BTU values of the ...
A dish of ethanol aflame. Various alcohols are used as fuel for internal combustion engines.The first four aliphatic alcohols (methanol, ethanol, propanol, and butanol) are of interest as fuels because they can be synthesized chemically or biologically, and they have characteristics which allow them to be used in internal combustion engines.
The Alternative Motor Fuels Act (AMFA) enacted in 1988 [15] provides Corporate Average Fuel Economy (CAFE) incentives for manufacturing alternative fuel vehicles (AFVs) that are powered by ethanol, methanol, or natural gas fuels, either exclusively or in conjunction with gasoline or diesel fuel.
Most gasoline used in the United States is blended to E10, which contains only 10% ethanol. The May 2015 rule changes thus created modest incentives to make greater use of E85 and E15, which contain more ethanol. [8] Many in the biofuel industry argue that the EPA abused its waiver authority by setting RVOs lower than the statutory minimums.
