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 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. In the United States, the exact ratio of fuel ethanol to hydrocarbon may vary according to ASTM 5798 that specifies the allowable ethanol content in E85 as ranging from 51% to 83%. [1]
Ethanol fuel is fuel containing ethyl alcohol, the same type of alcohol as found in alcoholic beverages. It is most often used as a motor fuel, mainly as a biofuel additive for gasoline. Several common ethanol fuel mixtures are in use around the world.
15 Φεβ 2024 · E85 is an ethanol-gasoline blend that may contain up to 85 per cent fuel ethanol and 15 per cent petrol. It’s found favour as a race fuel, and E85-powered vehicles are said to produce lower net CO2 emissions.
16 Μαρ 2018 · Ethanol is often mistaken or linked with a fuel called methanol, a wood- or petroleum-based alcohol that is especially corrosive when stored in solution with bare aluminum. Ethanol is not an acid and has little effect on aluminum fuel system components.
The general chemical formula for alcohol fuel is CnH2n+1OH. Most methanol is produced from natural gas, although it can be produced from biomass using very similar chemical processes. Ethanol is commonly produced from biological material through fermentation processes.
23 Απρ 2021 · Ethanol is a fuel used in combustion engines and is becoming more readily available at local gas stations. It is normally sold as “E85” and is made up of 85% ethanol and 15% unleaded gasoline (i.e. it’s content). Hence the name E85.
