Tequila: E85 Fuel A mixture of 85-percent ethanol and 15-percent gasoline, E85 is considered by many to be a poor-man’s race fuel – and for good reasons. Stanford University’s Mark Jacobson estimates that E85 fuel in “flex-fuel” vehicles may increase ozone-related mortality, asthma, and hospitalizations by 4 percent compared to gasoline by 2020 for the U.S. as a whole and 9 percent in Los Angeles alone. The motor racing industry has always preferred ethanol- or methanol-based fuels because these fuels tend to give performance vehicles more thermal efficiency and increased torque. Get detailed expert vehicle reviews and ratings for every car on the market. In Finland E85 is available from 52 St1 chain locations and 71 ABC chain locations. E85 also has higher octane content, which can provide more engine power. And because its distilled it burns colder thus allowing more advance in timing = "mo fun" For gas i get that 11AFR at Wot is utilized to keep heat down. There are many differences between E85 and gasoline. The percentage of ethanol depends on the geographical location and time of the year. In the United States, government subsidies of ethanol in general and E85 in particular have encouraged a growing infrastructure for the retail sale of E85, especially in corn growing states in the Midwest. On the face of it ethanol actually has a slightly lower energy content than gasoline per kilogram, but it also has a much richer stoichiometric AFR (9.8:1 for E85 vs 14.7:1 for pump gas) which means we need to use more of it to mix with the same mass of air. Joined Feb 9, 2008. The percentage of ethanol depends on the geographical location and time of the year. But an interesting change occurs with E85. The make and model of the vehicle, the way in which the ethanol was produced and the vehicle's overall fuel efficiency all play a large role in the overall outcome of each study. We use a BSFC of .55 for forced induction. Bear2013. [8], A study by Purdue University found that the economic benefit of E85 is highly dependent on the price of crude oil. Some say that cellulosic ethanol produced from waste materials or fast growing non-food crops such as switchgrass is much more beneficial, but not yet economically practical at large scale. It takes a while to start. Ethanol has been such a boon to the fuel industry that many gas companies are combining it with regular gasoline. These emissions are hydrocarbons (HC), oxides of nitrogen (NOx), carbon monoxide (CO) and carbon dioxide (CO2). Tailpipe emissions result from fuel combustion in a vehicle's engine. So I have been debating this for a while.. well since its Winter, and there's nothing else to really do. 1. Examples of octane mis-citation can be found at the Iowa Renewable Fuels Association titled "E85 Facts"[4] which cites a range of 100-105, and a document at the Texas State Energy Conservation Office titled "Ethanol",[5] which cites a 113 rating. Producers add more ethanol in the summer as opposed to the winter. On the other hand, E85 or 85% ethanol gasoline requires approximately a 9.85:1 AFR to achieve stoichiometric. All 2001-model standard vehicles and newer can run on E15 but can't handle the corrosiveness of higher ethanol percentages. Brazil makes theirs from sugarcane. There are a few major differences between FFVs and non-FFVs. Browse up-to-the-minute automotive news and analysis, including expert reviews of the latest cars on the market, at Cars.com. E85 advocates say that corn prices have increased due to manipulation of the commodities markets and because American corn companies sell more and more US-grown corn to Mexico and China, creating more competition for corn buyers, and therefore driving up its price. 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. It should be viable only within three months of packaging. E85 is an alternative fuel supported by many automakers on a wide range of cars. In Brazil, ethanol fuel is neat at the pumps, hence flexible-fuel vehicles (FFV) including trucks, tractors, motorbikes and mopeds run on E100. Kyle Brixey’s Trailblazer SS is no stranger to boost. 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%. 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 vs. GGE also compares gasoline to fuels sold as a gas (natural gas, propane, hydrogen) and electricity. [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. The most common use of manufactured ethanol is as a vehicle fuel for internal-combustion engines. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume.. However, vapor pressure for low-level ethanol blends can be adjusted to adhere to the same volatility standards as gasoline. E15 is gasoline with 15% ethanol content, and E85 is a fuel that may contain up to 85% fuel ethanol. 1,876 167. Tumelo. The tests have shown very little consistency if any at all because there are too many variables involved. Influence of ethanol-gasoline blended fuels on brake-specific fuel consumption. This compiled set of data showed that on average all emissions that are federally regulated showed a decrease or no statistically relevant difference between E85 and gasoline. The 2019 Ford F-150 provides a wide array of powertrain solutions to meet the requirements of a diverse group of owners. The average street engine usually runs about a .5 BSFC, so that is the figure we use for naturally aspirated engines. October 21, 2019 Reply . General Discussion. It can only be used in fuel systems designed specifically for E85 blends. 3. This fuel, which is popular in the US and sold under the E10, E20, e15 and E85 branding, is made up of up to 10% ethyl alcohol, which degrades very quickly. Most gasoline sold in the U.S. contains some ethanol, which is added as an oxygenator that reduces emissions. Gasoline gallon equivalent (GGE) or gasoline-equivalent gallon (GEG) is the amount of alternative fuel it takes to equal the energy content of one liquid gallon of gasoline.GGE allows consumers to compare the energy content of competing fuels against a commonly known fuel—gasoline. One is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system. Because ethanol is corn-based, E85 gas is readily available in the Midwest region of the United States. Fewer air pollutants released into the atmosphere, Less energy per gallon, leading to fewer miles per gallon. E85. There’s been a lot of controversy, but ethanol in petrol is here to stay. Outside the United States, ethanol producers often use alternative crops. 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%. For us, the E85 trip was about $30 more expensive — about 22.9 cents per mile on E85 versus 18.7 cents per mile with gasoline. David Freiburger and Steve Dulcich at Engine Masters wanted to find out which makes more power and by how much.So they grabbed a 489-cubic-inch, 13.5:1 compression big block Chevy, teamed up with our partners at Summit Racing for a couple of key parts, and started playing..
