In terms of its octane rating, ethanol has a rating of 113. As mentioned above, fuels with a higher octane rating reduce engine knocking and perform better. Also, almost all gasoline in the US contains 10 percent ethanol. When you mix 10 percent 113 octane ethanol with 85 octane gasoline it increases the octane two points to the normal 87 octane most consumers use. So the higher the ethanol content, the higher the octane. The octane rating for E15 (15% ethanol) is 88 octane and. Ethanol's Octane Increase Many oil refiners have lowered the target octane of gasoline leaving the refinery to take advantage of subsequent blending of ethanol downstream from the refinery. We estimate that approximately 80-85% of all gasoline leaving the oil refineries in the United States is around 83- 84 octane (AKI. • Ethanol's pure component octane number is 100 AKI. • But it's blending octane number is 109-119 AKI, depending on the octane of the finished fuel. • Ethanol's blending octane number is highest when used with lower-octane 108hydrocarbon blendstock
The octane rating (octane number) of ethanol gasoline in China is 90.0, 93.0 and 95.0 RON test method ( ASTM D2699 ). The octane number of ethanol gasoline is determined by the professional octane engine according to RON and MON test methods Where the octane number is raised by blending in ethanol, energy content per volume is reduced. Ethanol energy density can be compared with gasoline in heat-of-combustion tables. It is possible for a fuel to have a Research Octane Number (RON) more than 100, because iso-octane is not the most knock-resistant substance available
Best estimates of the actual octane rating of pure ethanol place it at about 100 octane. This is probably a conservative value but it is one we are comfortable with. If you see octane claims for ethanol in the 112 range, be suspicious that the octane number might be incorrectly based on BOV As mentioned above, fuels with a higher octane rating reduce engine knocking and perform better. Also, almost all gasoline in the US contains 10 percent ethanol. So the higher the ethanol content, the higher the octane. The octane rating for E15 (15% ethanol) is 88 octane and E85 (85% ethanol) is 108 octane. Click to see full answer We focus on the value of ethanol in the gasoline blend as an octane enhancer because there is ample evidence the market value of ethanol is related to its relatively high octane rating. While certainly not equivalent to a complete mathematical treatment of gasoline blending, a direct comparison of the price of ethanol and alternative sources of octane does shed some light on the question of the marginal value of ethanol as an octane enhancer. We first addressed the issue of the relationship. In Europa wird an den Tankstellen meist als Zapfsäulen-Oktanzahl die ROZ (Researched Oktanzahl) angegeben, in den USA dagegen meist die AON (Average Octane Number). Die AON muss dabei relativ aufwendig nach der Formel AON = (ROZ+MOZ):2 berechnet werden. Da die ROZ-Werte höher als die von MOZ oder AON und dazu noch einfacher zu berechnen sind, hat sich an den europäischen Tankstellen die ROZ durchgesetzt ELITE OCTANE OFFERS DIRECT DEPOSIT.

From January 2011, all 95-octane fuel in Finland is E10, and 98E5 octane fuel is also available. Mandatory blending of ethanol was approved in Mozambique, but the percentage in the blend has not been specified. South Africa approved a biofuel strategy in 2007, and mandated an 8% blend of ethanol by 2013 the lower chart is that ethanol has nearly twice the octane increase compared to toluene if adding up to 30% by volume. This is a huge economic benefit for consumers in the future when they can purchase E30 for less than E10 Regular, yet have more octane performance than any E10 Premium fuel in the market today Ethanol has a research octane number (RON) 108 . This is higher than gasoline, which is typically RON 92 to 97 . Ethanol has been widely accepted as a transportation fuel either in its pure form or in a blend with gasoline. Ethanol acts as an octane enhancer and its addition to gasoline helps to increase the mixture's octane number and thereby reduce tendency to knock . It has been. How does ethanol change gasoline and octane? If playback doesn't begin shortly, try restarting your device. Videos you watch may be added to the TV's watch history and influence TV recommendations.
Ethanol's pure component octane number is 100 AKI. But its blending octane number is 109-119 AKI, depending on the octane of the finished fuel. Ethanol's blending octane number is highest when used with lower-octane hydrocarbon blendstock Ethanol has a high octane rating and can be added to gasoline to produce high octane fuel blends. Understanding the octane increase with ethanol blending is of great fundamental and practical importance. Potential issues with fuel flow rate and fuel vaporization have led to questions of the accuracy of octane measurements for ethanol-gasoline blends with moderate to high ethanol content (e.g. 91 octane No Ethanol • Ethanol is political quackery at its best, just a way to subsidise farmers. • Ethanol is neither environmentally friendly, nor efficient in ANY way - effectively an abomination of biblical... • Ethanol reacts extremely badly with plastic gas tanks and especially seals, hoses.
Highlights Higher ethanol blend levels are projected for US gasoline. Ethanol has greater Research Octane Number (RON) and heat of vaporization (HoV) than gasoline. Linear molar octane blending model is used to quantify RON potential from ethanol and blendstock. Cooling octane from fuel evaporation in DI engines is estimated. Future engine efficiency increases are enabled by increased knock. With use of E85 ethanol and appropriate tuning, we saw a net gain of 64 WHP & 38 WTQ over 93 octane gasoline! The gains do not stop there either, E85 enables the limits to be pushed to levels typically only seen with race gas! Depending on how you use your vehicle, switching to ethanol may or may not be the right choice for you When you mix 10 percent 113 octane ethanol with 85 octane gasoline it increases the octane two points to the normal 87 octane most consumers use. So the higher the ethanol content, the higher the octane. The octane rating for E15 (15% ethanol) is 88 octane and E85 (85% ethanol) is 108 octane Ethanol's high latent heat ability cools the inlet air which lowers the engine's octane requirement. This may not sound like much but consider a study completed by the OE's back in the 1970s. The test determined that for every 25 degrees reduction in inlet air temperature, the engine's octane requirement was lowered by 1 full number
. To put that simply, higher octane gas resists detonation, so it burns rather than exploding. But raising the octane level of gasoline. Unleaded 88, also known as E15, consists of 15% ethanol and 85% gasoline. This fuel has a higher octane rating than regular 87 octane fuel, offering your engine a boost, and it burns cleaner than regular unleaded, improving our air quality and reducing greenhouse gas emissions Also question is, does premium gas have ethanol in Canada? You can get our 94 octane premium gas at over 700 locations in Alberta and Ontario. You can also find our equivalent SuperClean 94 at 215 locations in Quebec. Yes, all of our grades of gas, including our Ultra 94 high octane fuel, contain up to 10% ethanol content.. is Canadian Tire premium gas ethanol free Ethanol blending into gasoline yields a wide range of octane rating responses, most frequently synergistic (i.e., greater than expected by linear blending), but also linear or antagonistic. A new approach to modeling ethanol octane blending, applicable for both research octane number (RON) and motor octane number (MON), is proposed, which predicts different ethanol blending responses in base.

Audi to compete in Dakar Rally in 2022 with series-hybrid electric prototype; factory team leaving Formula E Ethanol has a high octane rating and can be added to gasoline to produce high octane fuel blends. Understanding the octane increase with ethanol blending is of great fundamental and practical importance. Potential issues with fuel flow rate and fuel vaporization have led to questions of the accuracy of octane measurements for ethanol-gasoline blends with moderate to high ethanol content (e.g., E20-E85) using the Cooperative Fuel Research (CFR™) engine. The nonlinearity of octane. Ethanol has a research octane number (RON) 108 . This is higher than gasoline, which is typically RON 92 to 97 . Ethanol has been widely accepted as a transportation fuel either in its pure form or in a blend with gasoline. Ethanol acts as an octane enhancer and its addition to gasoline helps to increase the mixture's octane numbe Can ethanol boost gasoline's octane rating? Yes. Ethanol has a much higher octane rating (about 109) than gasoline. Refiners usually blend ethanol with gasoline to help boost its octane rating—most gasoline in the U.S. contains up to 10% ethanol. Blends of up to 15% ethanol are available in some areas, and several manufacturers approve using this blend in recent-model vehicles
Ethanol blends synergistically with n -heptane and isooctane in octane numbers Q. Can Ethanol Boost Gasoline's Octane Rating? A. Yes, adding ethanol will boost gasoline's octane rating. Ethanol has an octane rating of roughly 110, give or take a few This calculator will calculate the octane and percent of ethanol from a mixture of E85/Ethanol and gasoline. (one could use straight ethanol or even methanol, use appropiate octane rating) Calculate Ethanol % of Mixture: Fuel Mix: GALLONS: (Ethanol) Octane: % Ethanol: Fuel Mix : GALLONS: Gas Octane: % Ethanol: Input All Data, Please The equivalent octane of E85 can be from 105 to 109 or so.
Compared to poisonous lead and carcinogenic benzene-based octane boosters that the oil industry prefers, ethanol is a superior gasoline octane booster. Today's cars require higher octane for better efficiency and lower emissions. The U.S. Department of Energy recently singled out E30 blends as the best way for automakers to get the higher-octane gasoline they need. Premium E30 blends would save consumers at the pump, and substantially reduce harmful emissions Ethanol actually raises octane. A bunch of gas stations have made it so only the highest grades are ethanol free, as a way to rip off the older engine community. Overall, ethanol is a high octane fuel. Understanding octane is another matter entirely for most of the public though. They think high octane increases power or efficiency. It doesn't have anything to do with either. It has to do with detonation at a compression psi . A government investigation headed by then Treasury Secretary Andrew Mellon concluded tetra-ethyl lead (TEL) was a safe additive, despite overwhelming historical evidence to the contrary. Mellon was owner of Gulf Oil, the exclusive distributor of leaded gasoline in the South. A.
Nick Bowdish is responsible for the overall management of Elite Octane and has a track record of executing the tasks needed to meet the strategic goals and objectives of operating a dry mill ethanol plant. Mr. Bowdish currently provides these services as President of N Bowdish Company, formed in 2013 to provide project development and management services to the grain and ethanol industries. In addition to Elite Octane, N Bowdish Company provides services consistent with the role of President. Il en résulte que le mélange eau/éthanol pompé puis injecté dans les cylindres possède un indice d'octane inconnu et aléatoire dont les conséquences potentielles sont une détérioration de la pompe d'injection, des buses d'injecteurs mais surtout un fonctionnement anarchique du moteur se soldant à terme par une fragilisation prévisible voire une casse des organes internes, les plus exposés étant encore une fois les coussinets, les pistons, les soupapes et dans une moindre mesure la culasse
Ethanol's high octane value and green advantages have also led ethanol to the world of motorsports. The cars in the 2012 Indy 500 ran on E85 while from 2011, NASCAR's top three national series raced with Sunoco Green E15, which contains 15% ethanol. As at November 2013, over five million miles have been driven using Sunoco Green E15. Tweet Other Facts. Ethanol and the Economy. Ethanol. When expressed using volumetric concentrations (as is industry practice), the addition of relatively small amounts of ethanol or methanol (e.g., 10% by volume) to gasoline appears to result in disproportionately large, nonlinear increases in research octane number (RON) and motor octane number (MON). As a result, volumetric blending octane numbers are of limited value for estimating the octane number of alcohol−gasoline blends because they vary with alcohol content and base gasoline. Ethanol Content: 85%. Effective Octane: 112. Specific Gravity: 0.783 at 68° F. Street Legal: No. No MTBE, nitromethane, or lead. One Ethanol S is high performance E85 fuel built for racers with powerful engines requiring precise and consistent ethanol content. S is intended to be used in forced induction, nitrous, and N/A engines that typically use race fuels with an octane rating of 100 to 112 Ethanol's 113 octane rating makes it a desirable octane booster in gasoline-ethanol blends, but if low-octane fuels begin to become acceptable in the marketplace, despite automaker warnings and environmental concerns, ethanol's high-octane rating won't carry as much value. To be fair, refiners would probably continue blending ethanol to bring the lower octane base fuels up to whatever. 90 octane Ethanol free gas or 93 octane 10% ethanol...

Thread starter #1 Which would you run? Just wondering what your thoughts are. I have a buddy who has a large car collection and everything he drives uses the ethanol free.
It could be that I'm giving the wrong impression here but on a cold winter's evening there is nothing I like so much as a small glass of whisky. Settling into my favourite armchair alongside the dying embers of a log fire and savouring the delights to come, I watch carefully as the dash of tepid water (not too much now!) is added to the tumbler and then slowly mixes. That it does so is one of. Pure ethanol is 113 octane so adding 10% to 93 gasoline adds to the octane rating. E85 is 108 octane, that's why is a big plus. Remember, the octane ratings at the is E85 is 108 octane, that's why is a big plus
ManicMechanicMD said: The only ethanol-free fuel available in my area is 87 octane only. Even the 10% ethanol Premium fuel is only 91 octane. My question for you all is your opinion on that More than 98% of U.S. gasoline contains up to 10% ethanol to boost octane, meet air quality requirements, or satisfy the Renewable Fuel Standard. E10 does not qualify as an alternative fuel under the Energy Policy Act of 1992(EPAct). E15 E15 is a low-level blend composed of 10.5% to 15% ethanol and gasoline This paper reports the Research (RON) and Motor (MON) Octane Numbers of gasoline blended with an oxygenated compound ethanol. The ethanol concentration was varied from zero to 20%, resulting. Worldwide, the leading gasoline octane improvers are fuel ethanol, MTBE, methanol (primarily in China), and ETBE. TAME is the smallest of the major octane improvers. Most of the growth of fuel ethanol consumption is mandated by government regulations designed to reduce vehicle emissions. The United States is the largest consumer of gasoline and gasoline octane improvers, nearly all of which is fuel ethanol. In the United States, reformulated gasoline (RFG) - gasoline blended to burn more.
Ethanol also reduces Greenhouse Gas (GHG) It is a high-octane fuel that generates more power in higher compression engines. Available now, ethanol helps to reduce global dependence on fossil fuels and can be used to diversify a country's energy matrix. Click here to learn from Brazilian experience on a cleaner air.

General Discussion. patrickmc5 July 4, 2016, 9:58pm #1. My father-in-law just introduced me to a site where you can see locations of gas pumps in the U.S. that provide ethanol free gas. After taking a look around my area, I found that there is a station close by that provides ethanol free, however it.
When the ethanol sinks out of the gasoline, it lowers your octane rating significantly, but that's the least of your worries at this point. The water can corrode your gas tank leading to rust, and you're in for a world of hurt if that water gets sucked into your engine. The only way to fix phase separation once it has occurred is by completely draining your gas tank The 88 octane non-ethanol is probably better that the 91 with ethanol. #10. Phoenix101 likes this. Saltboxlad, Nov 13, 2019 #11. Saltboxlad Long timer. Joined: Jan 13, 2015 Oddometer: 3,883 Location: Wales, UK. The only bike Ive ever noticed a significant performance difference with high octane was my BM K1300GT. They advised 97 for full performance and economy but you could run it on 95 #11. The octane premium ranged from about $5 billion to about $24 billion dollars and averaged $13.8 billion (Figure 10). The calculated net value of ethanol in the domestic gasoline blend ranged from -$8.56 billion in 2016 to $14.3 billion in 2012 (Figure 11)
In fact, pure ethanol has an octane rating of 113! So if you're looking for some homegrown, clean burning power for you engine, fill up like the pros and use E15 or E85. DDGS. When we talk about ethanol, we can't forget that all of that corn that goes into an ethanol plant doesn't just come out as fuel but 1/3 of the corn comes back out as DDGS. What are DDGS? If you ask a cow, it's the. Without the ethanol, where's the octane coming from? Marketers seem to be blending regular and premium CBOB together to make the desired octane of the product they offer for sale. A 50/50 blend of 84 octane regular CBOB + 90 octane premium CBOB (East of the Rockies) should create an 87 octane gasoline. (Caution the BOBs are not always at the octane rating assumed in the previous statement. REC-90 is an ethanol-free, 90 octane unleaded gasoline blend designed for use in recreational/marine engines which can be damaged by the ethanol found in other gasoline blends. It is also usable in some aviation engines and automotive engines, though it has not been thoroughly tested for cars and trucks Refiners add ethanol to gasoline to increase the fuel's oxygen content and to comply with federal law. As a side benefit, ethanol is one of a few gasoline components with a high octane rating. Nonoxygenated gas doesn't contain ethanol, so it eliminates corrosion problems when left in the fuel system for long periods.Feb 28, 2020
Ethanol's octane value. In the US, a step-up of one grade of gasoline (regular to mid-grade, or mid-grade to premium), costs $0.238 this week at retail, according to the US Energy Information Administration. That's for two points in octane rating. From that, we can imply a retail value of 11.9 cents per octane point, in today's market. Ethanol has a 32 point octane blending value. Ethanol is a low cost source of octane - Since 2010, ethanol has been cheaper than either alkylate or reformate by over 0.7 cents per octane liter. Source: Derived from Platts, Argus, and OPIS data . Ethanol vs. MTBE Blending Economics • Since 2010, MTBE has been more expensive than ethanol by ~16.6 cents per liter. • Since 2010, a 10% ethanol blend of finished gasoline (3.5% oxygen) is. Common anti-knock additives include 101-octane benzene, 111-octane touline, 117-octane xylene, 118-octane isopropanol, 129-octane ethanol and 133-octane methanol. Almost all of these have, at various points, been used as race fuels by themselves; touline was used in Formula 1 for some time, and ethanol and methanol are still used today. Most of these are types of alcohols, like the ethanol or. The ethanol injection suppresses knock so that higher compression ratio and/or engine downsizing from increased turbocharging or supercharging can be used to increase the efficiency of the engine. Fuel management system for variable ethanol octane enhancement of gasoline engine It's quite possible for the stations that sold the 94 octane Husky/Mohawk (at least back when they did), it may have had significant ethanol content to allow them to have 87 octane non-ethanol? As for fuel economy, the best I've got out of the 2UZFE was 13.3L/100km on Shell 91V power, next closest was CT Premium at 13.5L/100km. The best I could.
Does ethanol in equal octane gasolines have performance benefits! I've seen different opinions but let's say a turbo engine that needs 91, your option is 91 Ethanol 0 or 91 Ethanol 10%. Both cars are 91 octane so their knock resistance should be the same however we know ethanol is more knock resistant. So since the anti knock index of both fuels is. Ethanol has a very high octane quality, and so is a valuable blending component for use in the production of high octane unleaded petrol. Its use in this application is limited to 5% volume and is acknowledged by a label on the pump according to the Tesco help line, although this may not always be the case. Although the EU is believed to be considering the mandatory use of bio-ethanol in. Adding ethanol to gasoline even in low percentages, such as 10% ethanol and 90% gasoline (E10), reduces carbon monoxide emissions from the gasoline and improves fuel octane Our ethanol is a high-quality, high-octane fuel which: Is made from renewable crops and resources. Reduces lifecycle greenhouse gas emissions from transportation fuels. Supports local agriculture by providing a value-added market for grains. Provides consumers with an affordable, more environmentally friendly fuel at the pump. Greenfield's commitment to sustainability is evidenced not only. Draining off the ethanol will likely lower the octane level, usually by about 3. Start with a higher gasoline level if you need a standard octane level. Start with a higher gasoline level if you need a standard octane level
Request PDF | Ethanol C2H6O + C8H18 Octane | This document is part of Subvolume A1 'Binary Liquid Systems of Nonelectrolytes. Part 1' of Volume 13 'Vapor-Liquid Equilibrium in Mixtures and. The research octane of ethanol is impressively high, which is a beautiful thing for high-compression and high-boost applications. However, its motor octane (the more extreme standard) is.

The octane enhancement effect can be estimated from the data in FIG. 2. Direct injection of gasoline results.. Interesting- but cool. I'd agree with my knowledge of fuels octane points are important 10 points to = 1 octane level. The difference between 91 and 93 is a lot... So ethanol or not- 93 is still 93. Is there 93 in STL that I'd rather use? Sure- my friends have their fav places.... No choice here though.I honestly thing the ethanol messes more with the old cars and less with fuel injected cars of new with an ECU that can sort it all out. So really, I'm just going to get really good. April 22, 2009. Ethanol (C2H5OH), otherwise known as ethyl alcohol, alcohol, or grain spirit, is a clear, colorless, flammable oxygenated hydrocarbon with a boiling point of 78.5 degrees Celsius in the anhydrous state. In transportation, ethanol is used as a vehicle fuel by itself (E100), blended with gasoline (E85), or as a gasoline octane.
One Ethanol S is high performance E85 fuel built for racers with powerful engines requiring precise ethanol content. S is intended to be used in forced induction, nitrous, and N/A engines that typically use race fuels with an octane rating of 100 to 112.

Accordingly, high RON ethanol blends containing 20 vol% t provided octane to gasoline, preventing engine knock.3 While aromatic hydrocarbons (such as benzene) and alcohols (such as ethanol) were also known octane providers at the time, lead was the preferred choice due to its Fig. 1: octane rating of gasoline, as displayed at a typical gas station L'octane est un hydrocarbure saturé de la famille des alcanes, de formule brute C 8 H 18.Il a dix-huit isomères.Ces diverses molécules comportent toutes huit [en grec ὀκτώ (octố), huit] atomes de carbone.. Utilisation. C'est le principal composé de l'essence, et est la molécule de référence de la réaction de combustion des moteurs à « essence » Any engine built in the last few years, however, is engineered and built with understanding that it will likely see ethanol blended gas, so this is not nearly the problem that it was years ago. OTOH, ethanol IS hygroscopic - so it will pull water out of humid air and into your fuel. This is a significant issue in humid areas (lakes or oceans) and Florida certainly has a lot of humidity Ethanol has very high research octane number (RON) and heat of vaporization (HoV), properties that make it an excellent spark ignition engine fuel. The prospects of increasing both the ethanol content and the octane number of the gasoline pool has th
