Bear2013. Advertisement. The ethanol content of most of the motor gasoline sold in the United States does not exceed 10% by volume. Since its 85% ethanol Vs 10% ethanol (Gas) And proportionally the octane in gas is 91-93 Vs E85 being 100. [12] E85 as a fuel is widely used in Sweden; however, most of it is imported from Italy and Brazil. E85 (or flex fuel) is a term that refers to high-level ethanol-gasoline blends containing 51% to 83% ethanol, depending on geography and season (see Fuel Properties and E85 Flex Fuel Specification). Sunoco E85-R is an unleaded racing fuel containing 85 volume % ethanol. Gas mileage with ethanol free vs 10% ethanol. One is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system. Gasoline or E85 ethanol-blended fuel? JK 3.8 Stage 2 vs. To better judge ethanol's strengths and weaknesses, we decided to buy a flex-fuel vehicle (FFV) and put E85 to the test. Stage 3 Let's take it back to 2008, our owner and founder, Wes, had just finished a 5.7 HEMI swap for a ... E85 Ethanol vs. 93 Octane Gasoline [1] This is due to the lower heating value of neat ethanol making it difficult to crank engines in relatively cold climates without pre-heating air intake, faster cranking, or mixing varying fractions of gasoline according to climate. E85 vs. !!!!!10/29/2014! In Finland E85 is available from 52 St1 chain locations and 71 ABC chain locations. In Austalia, E85 is the preferred fuel among motor racing clubs and sports car enthusiasts. Regular gasoline sold in the U.S. usually contains up to 10 percent ethanol. Critics of E85 and ethanol, in general, argue that its lower heating value outweighs any benefits.

On the other hand, E85 or 85% ethanol gasoline requires approximately a 9.85:1 AFR to achieve stoichiometric. However comparing energy expressed as a value of heat does not reflect the total work from an Otto Cycle[citation needed]. The Renewable Fuels Association defines a flex fuel as a blend of ethanol and gasoline that contains more than 15 percent ethanol and less than 83 percent ethanol. If you can't afford to go electric or fuel cell right now and want a cleaner burning fuel in place of gasoline, choose E85. ! Others say that the world can easily replace all of its use of petroleum by simply making ethanol from the many crops that yield more ethanol per acre than corn yields, with existing technology, not future technology,[11] and that certain elements in the cellulosic ethanol field are more interested in patent rights than in producing the greatest amount of ethanol at the lowest price point. The octane rating of pure ethanol is 100, but when it’s blended with gasoline, it performs as if it’s 112. The variation of brake power with speed was obtained at full load conditions for E5, E10, E20, E30, E50, and pure gasoline E0. So I have been debating this for a while.. well since its Winter, and there's nothing else to really do. Feb 7, 2013 #1. E85 was at least 20% less expensive in most areas as recently as 2011. The 2008 Farm Bill reduced the VEETC's 51-cent tax credit to 45 cents. All 2001-model standard vehicles and newer can run on E15 but can't handle the corrosiveness of higher ethanol percentages. Using a guaranteed fraction of ethanol makes it easier for a vehicle to reach peak performance and fuel economy. While it has been around for quite some time, it is just now starting to take hold in the US. [6] To address the problem of inaccuracy, engineers at the National Renewable Energy Laboratory combined data from all applicable emissions studies and compiled them into one data set. https://afdc.energy.gov/fuels/ethanol_e85.html, https://www.eia.gov/todayinenergy/detail.php?id=18551, https://www.cars.com/articles/what-is-a-flex-fuel-vehicle-410045/, https://www.caranddriver.com/features/a15122210/ethanol-injection-systems-explained-tech-dept/, https://www.fueleconomy.gov/feg/ethanol.shtml, https://www.caranddriver.com/features/a15145172/ethanol-promises/, https://www.sae.org/publications/technical-papers/content/2002-01-2743/, 627-HP 2022 BMW M5 CS Will Be the Ultimate M5, Mach-E California Route 1 EPA Range Revealed, Biden to Replace U.S. Fleet Vehicles with EVs, Tested: Genesis GV80 2.5T Has a Powerful Four, This content is created and maintained by a third party, and imported onto this page to help users provide their email addresses. The most common use of manufactured ethanol is as a vehicle fuel for internal-combustion engines. October 21, 2019 Reply . General Discussion. The Society of Automotive Engineers and other supporters of E85 usage argue that if automotive manufacturers would recognize and take advantage of ethanol-based fuel's superior traits, they could make an ethanol engine that was as efficient as one powered by gasoline.
