What Is E85 Ethanol???

E85 is an alcohol fuel mixture of 85% ethanol and 15% gasoline, by volume. Ethanol is derived from crops (bioethanol) is a biofuel. Ethanol is a renewable resource.

E85 as a fuel is widely used in Sweden and is becoming more common in the United States, mainly in the Midwest where corn is a major crop and is the primary source material for ethanol fuel production.

E85 is usually used in engines modified to accept higher concentrations of ethanol. Such flexible-fuel engines are designed to run on any mixture of gasoline or ethanol with up to 85% ethanol by volume. The primary differences from non-FFVs is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system, the use of fuel pumps capable of operating with electrically-conductive (ethanol) instead of non-conducting dielectric (gasoline) fuel, specially-coated wear-resistant engine parts, fuel injection control systems having a wider range of pulse widths (for injecting approximately 30% more fuel), the selection of stainless steel fuel lines (sometimes lined with plastic), the selection of stainless steel fuel tanks in place of terne fuel tanks, and, in some cases, the use of acid-neutralizing motor oil. For vehicles with fuel-tank mounted fuel pumps, additional differences to prevent arcing, as well as flame arrestors positioned in the tank's fill pipe, are also sometimes used

Use of E85 in non-FFV vehicles is generally experimental, with some users recommending light blends as low as 20%, while others have successfully run 100% E85. The main attraction of burning E85, of course, is the lower price per gallon at the pump of E85 versus gasoline. Other advantages include the common benefits of renewable energy sources, such as less environmental impact and less reliance on foreign energy.

Use of E85 results in reductions of greenhouse gas emissions and energy use for each gallon burned, compared to the emissions and energy use for the gasoline it replaces.

Using corn based fuel ethanol production, E85 has a significant impact on total fossil fuel / energy usage and greenhouse gas (GHG) emissions. As process efficiency increases over the coming years, these benefits are expected to continue to improve.
