Ethanol e-85

Ethanol e-85Bend Oregon's Only E-85 station. E85 is an alcohol fuel mixture that typically contains a mixture of up to 85% denatured fuel ethanol and gasoline or other hydrocarbon (HC) by volume. A University of Nebraska study in 2009 showed corn ethanol emits 51% less greenhouse gas than gasoline, & the U.S. Department of Energy has published facts stating that current corn-based ethanol results in a 19% reduction in greenhouse gases, and is better for the environment than other gasoline additives such as MTBE. There has been some debate about E-85s environmental impact in recent years. It is important that adversaries of E-85 studied first gernation ethanol. This could be compared to studying the first IBM computer in 1980 and then saying well it took more time to work it than it saved. Second generation ethanol from corn, as a fuel available now, and cellulose ethanol in the future, are both much better fuels for the environment. Ethanol derived from sugar-beet as used in Europe or sugar-cane as grown in Brazil in industrial scale is generally seen as having a very positive CO2 balance with up to 80% reduction in well-to-wheel CO2. E-85 ethanol is used in engines modified to accept higher concentrations of ethanol. Such flexible-fuel vehicles (FFV) are designed to run on any mixture of gasoline or ethanol with up to 85% ethanol by volume. There are a few major differences between FFVs and non-FFVs. One is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system. Another is that fuel pumps must be capable of operating with electrically conductive ethanol instead of non-conducting dielectric gasoline fuel.
