We sent 22 of the most popular in-tank fuel pumps to be flow tested at an independant testing facilty so we can see which pumps flow more than others at various pressures and voltages, and then we made the results public to everyone. Because of its low price (less than $2.00/gal in some places) and high availability in certain areas people have started to turn to using it in place of high-end racing fuels, which typically cost over $10.00/gal. Flex fuel, or flexible fuel, is an alternative fuel made of a combination of gasoline and methanol or ethanol. [3] 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. A FREE E85 ethanol content fuel tester is included with every conversion. c Retail hydrogen stations accept payment at the point of sale. The tests have shown very little consistency if any at all because there are too many variables involved. For example, E85 is less volatile than gasoline or low-volume ethanol blends, which results in fewer evaporative emissions. 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. 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. The most common blend of ethanol is E10 (10% ethanol, 90% gasoline). As more effort is put into maximizing an engine to take advantage of E85's higher "octane", engines achieve greater power advantages. In the United States, to realize equivalent fuel economy at the pump with an FFV, the price of E85 must be much lower than gasoline. Shipping address: 8517 Idlewild Rd. Prices start at only $395/4150 and $435/4500. [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. Ethanol is also available as E85 (or flex fuel)—a high-level ethanol blend containing 51% to 83% ethanol, depending on geography and season—for use in flexible fuel vehicles. [16][17] Flex fuel gas mileage tends to be somewhat less than standard gasoline mileage. Utilizing OEM fuel and electronic connectors, the Ethanol Sensor Kit measures the ethanol content of fuel being fed to the motor. Because of the lower heating value E85 has a cooler intake charge—which, coupled with its high stability level from its high octane rating—has also been used as a "power adder" in turbocharged performance vehicles. The 85% fraction is commonly sold at pumps worldwide (outside the US), and when specifically supplied or sold as E85 is always 85% ethanol (at pumps or in barrel). 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. Understanding why E85 makes better power than pump gas is important. There are a few major differences between FFVs and non-FFVs. Alternative Fuel and Advanced Technology Vehicles, Project Assistance & Funding Opportunities. [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.

In Brazil, ethanol fuel is neat at the pumps, hence flexible-fuel vehicles (FFV) including trucks, tractors, motorbikes and mopeds run on E100. Fuel injection control systems have a wider range of pulse widths to inject up to 34% more fuel (which in turn produces more power). However, E85 can further reduce emissions of certain pollutants as compared to conventional gasoline or lower-volume ethanol blends. E85 advocates counter that concern by pointing out that over 93% of all corn grown in the United States is never fed directly to people, but is instead used as livestock feed[citation needed]. For a flex-fuel vehicle, E85 is already compatible with all engine parts. All you need to worry about is optimization. E15, another blend, is increasing its market presence. Because E85 is predominantly ethanol, the exhaust emissions are very different from those of regular gasoline. However, in Australia, where Holden has sold more than 70,000 FFVs since 2010, the difference in combined consumption on similar V8 variants in a family sedan is between 10% and 20%. Other measures taken by Congress to jump start ethanol production include the 2004 VEETC bill, which provided for a Small Ethanol Producer Tax Credit which gave tax credits to small ethanol producers. [12] E85 as a fuel is widely used in Sweden; however, most of it is imported from Italy and Brazil. 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%. 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. A complete plug and play solution enabling users to convert their supported Subaru WRX to a Flex Fuel configuration. The screen as set up here reveals an ethanol percentage of 50.6, the engine is idling at 12.7 inches of mercury (“Hg), Lambda is currently at 0.95 (equivalent to a 13.95:1 air-fuel ratio), and the fuel temperature is 70.6 °F. This page was last edited on 5 January 2021, at 00:02. It is approved for use in model year 2001 … They claim that some ethanol engines have already produced 22% more miles per gallon than identical gasoline engines.[2]. 200 GPH Dominator In-Line Billet Fuel Pump. This gauge uses a factory GM flex fuel sensor to quickly calculate the percentage of ethanol in the system. I need to get some E85 gas right now. E85 was formerly available from the Maxol chain in Ireland, where it was made from whey, a byproduct of cheese manufacturing. About Us. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume. [9], E85 critics contend that production of ethanol from corn (maize) drives up world food prices, causing corn to be unaffordable or even unavailable. Ethanol is a renewable fuel made from corn and other plant materials. E85 is increasingly 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. For vehicles with in-tank-mounted fuel pumps, precautions to prevent arcing, as well as flame arrestors positioned in the tank's fill pipe, are sometimes used. Some vehicles can be converted to use E85 despite not being specifically built for it. E15, another blend, is increasing its market presence. About the only thing that is the same or better is the octane rating, as ethanol does raise the octane level. also state that it is a mistake to base ethanol engine design on gasoline engine design, and that ethanol engines should be based on diesel engine design parameters instead. However comparing energy expressed as a value of heat does not reflect the total work from an Otto Cycle[citation needed]. The inadequate fuel pressure/volume when the pump was in low-speed mode was causing longer injector pulse widths to keep the oxygen sensors happy, thus fooling the PCM into inferring a much higher alcohol content than actually existed. E85 ethanol is used in engines modified to accept higher concentrations of ethanol. Search for the most efficient hybrid, diesel, and alternative fuel vehicles. Numerous studies have compared and contrasted the different emissions and the effects these emissions have on the environment, but the tests have been inconclusive. E85 advocates reply by pointing to ethanol producers who do not do so, but instead use E85 or biodiesel fuel to transport E85, and use biomass as a heat source for the distillation of ethanol instead of petro-products like natural gas. Check it out [citation needed]. Find information about ethanol blends, specifications, production and distribution, and feedstocks. This website offers a simple and easy-to-use fuel locator, after you’ve selected the category (such as ‘Diesel’ or ‘Open 24 hours’), or a particular gas company (such as Shell or BP) from the menu, you’ll be presented with maps that will show you exactly where are … According to the manufacturer, this is due to the cooling properties of ethanol. E85 is the designation for an ethanol-blended fuel where ethanol makes up 85-percent of the content, and gasoline 15-percent. This allows it to be used in higher-compression engines, which tend to produce more power per unit of displacement than their gasoline counterparts. EPA is conducting additional analysis to expand our understanding of the emissions impacts of E85. Stainless steel fuel lines, sometimes lined with plastic, and stainless-steel fuel tanks in place of terne fuel tanks have been used. Because energy content does not factor certain latent or specific heat values[citation needed], nor combustion pressure, so looking at heat alone in the combustion equation does not determine efficiency or work according to the laws of thermodynamics. About the fuel locator. Ethanol advocates[who?] The American Jobs Creation Act of 2004 created the Volumetric Ethanol Excise Tax Credit (VEETC) to subsidize production costs. The IRFA brings Iowa ethanol and biodiesel producers together to develop and grow Iowa's liquid renewable fuels industry through education and development. Charlotte, NC 28227 59 (Issue 8), Atmospheric Environment, Vol. It is approved for use in model year 2001 and newer light-duty conventional gas vehicles. The 2008 Farm Bill reduced the VEETC's 51-cent tax credit to 45 cents. E85 is an abbreviation typically referring to an ethanol fuel blend of 85% ethanol fuel and 15% gasoline or other hydrocarbon by volume.. More recently, the Tax Relief Act, Unemployment Insurance Reauthorization Act, and Job Creation Act of 2010 extended the tax cuts allowed by VEETC from the end of 2010 to the end of 2012. Today, sophisticated renewable fuel refineries use state-of-the-art technologies to convert grains, beverage and food waste, cellulosic biomass and other products called feedstocks into high-efficiency ethanol. One is the elimination of bare magnesium, aluminum, and rubber parts in the fuel system. In Finland E85 is available from 52 St1 chain locations and 71 ABC chain locations. There are four primary types of pollutants scientists study. In 2010, the cost of gas in the US averaged $3.42, while the cost for E85 averaged $3.09, or 90% of the cost of gasoline. Find laws and incentives related to ethanol in your area. Explore the benefits and considerations of using ethanol as a vehicle fuel. Using E85 also reduces carbon-monoxide emissions and provides significant reductions in emissions of many harmful toxics, including benzene, a known human carcinogen. Corn used to produce ethanol contains a high amount of starch and is not easily digestible by humans, like sweet corn. Locate ethanol fueling stations in your area and learn about ethanol fueling infrastructure. 45, Issue 39, Learn how and when to remove this template message. E85 critics contend that ethanol producers may not reduce carbon emissions due to the petroleum and natural gas used in raising corn and refining it. For E85 or other high alcohol fuels, this means a richer air-fuel ratio (9.8:1) is required. In one US test, an early model 2.75-ton Chevy Tahoe FFV averaged 18 MPG (U.S. gallons) for gasoline and 13 MPG for E85, 28% worse than gasoline. In the US such FFVs are designed to run on any mixture of gasoline or ethanol up to 85% ethanol, whereas in countries such as Brazil where the climate is typically warmer, FFV run on neat alcohol. With Flex Fuel E85 and advanced diesel locations across California, Propel provides new fuel choices that are higher in performance, deliver better value and create healthier communities. By way of international price comparison, in the Cook Islands as with many of the Pacific Islands, cost of producing 100% ethanol from coconut biomass is a fraction of obtaining fossil fuels. The fleet of flexible-fuel vehicles in the United States is the second largest in the world after Brazil, and there were more than 21 million 85 flex-fuel vehicles registered in the country by the end of 2017. [citation needed], E85 promoters and the Society of Automotive Engineers contend that automotive manufacturers currently fail to equal the fuel consumption of gasoline because they fail to take advantages of characteristics which are superior in ethanol-based fuel blends. E85 was at least 20% less expensive in most areas as recently as 2011. Where the engine was previously knock limited by gasoline, power improvements are as high as 40%. E85 has an octane rating higher than that of regular gasoline's typical rating of 87, or premium gasoline's 91-93. Having a guaranteed ethanol fraction obviates the need for a vehicle system to calculate best engine tune according to maximise performance and economy. Ethanol is also available as E85 (or flex fuel)—a high-level ethanol blend containing 51% to 83% ethanol, depending on geography and season—for use in flexible fuel vehicles. However, E85 in certain engine operating conditions may increase emissions of acetaldehyde. Propel connects consumers to better fuels. In contrast, ethanol critics contest the benefits of E85 by focusing on the fact that E85 has 33% lower heating value compared to the higher heating value of gasoline. 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%. Most fuel tuners on the market have the stoich point (optimal air/fuel ratio) set for traditional gasoline. [clarification needed] Although if you were to look at the advertising, it would appear that the mileage is the same. These modifications have not only resulted in lower GHG emissions, but typically resulted in 10-12% power and torque increase at the wheels. E85 has a few issues you need to take into account before using it. 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. [19][20] In another test, however, a fleet of Ford Tauruses averaged only about 6% fewer miles per gallon in ethanol-based vehicles when compared to traditional, gas-powered Tauruses. [21], The examples and perspective in this article, The examples and perspective in this section, US EPA/OAR/Office of Transportation & Air Quality/Advanced Technology Division and FEV Engine Technology; Inc. "Economical, High-Efficiency Engine Technologies for Alcohol Fuels", Journal of the Air & Waste Management Association, Vol. Mileage is dependent upon the composition of the ethanol-gasoline blend, transmission, state of engine tune (primarily fuel-air mixture, spark timing and compression ratio). In some cases, FFVs use specific engine oil that neutralises acidity. That work continues today through Holley’s market-leading EFI products as well as through Holley’s family of best-in-industry brands. In the United States to offset this difference in fuel consumption in vehicles not optimised for ethanol, legislation has been passed to subsidize its cost. Use the map to locate the nearest E-85 petrol station to where you are, it … Non-retail hydrogen stations are only available to a … In countries like Australia where E85 is always 85% ethanol (and pump fuel with varying fractions is called "flex fuel"), performance motoring enthusiasts and motor racing clubs/championships use E85 extensively (without the need for any FFV certification). One car that has higher power on ethanol is the Koenigsegg CCXR, which on ethanol is the fifth-most powerful production car, with 20% more hp on E85 than on gasoline. [14][15] The E85 sold by St1 is labeled as RE85 and as "Eko E85" in ABC-stations to indicate it is manufactured from Finnish bio-waste. American farmers grow more corn than people purchase; there is an annual surplus of corn in the U.S.[10]. While the concept is the same today as it was then, the ethanol industry has come a long way since those days. Use of alcohol (ethanol and methanol) in motor racing history parallels the invention of the automobile, favoured due to inherent combustion characteristics such as high thermal efficiency, raised torque and with some advanced engines, better specific fuel consumption. Cold cranking in cold climates is the primary reason ethanol fuel is blended with any gasoline fraction. As of July 1, 2014, there were more than 3,300 fuel stations that offered E85 fuel. 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. Handbook for Handling, Storing, and Dispensing E85 and Other Ethanol-Gasoline Blends. This is the easiest to use and most sophisticated Flex Fuel kit on the market. [7], EPA's stringent tier-II vehicle emission standards require that FFVs achieve the same low emissions level regardless whether E85 or gasoline is used. Mileage ratings for diesel, electric, hybrid, plug-in hybrid, natural gas, and flex-fuel vehicles. For over a century Holley has driven the cutting edge of fuel-system design. [13] The availability ended in 2011, due to a severe excise-duty hike which rendered it economically unviable.
