As more effort is put into maximizing an engine to take advantage of E85's higher octane rating, engines achieve greater power advantages. 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 horsepower on E85 than on gasoline. According to the manufacturer ...
High percentage ethanol mixtures are used in some racing engine applications as the very high octane rating of ethanol is compatible with very high compression ratios. Ethanol fuel mixtures have "E" numbers which describe the percentage of ethanol fuel in the mixture by volume, for example, E85 is 85% anhydrous ethanol and 15% gasoline. Low ...
In the aftermath of Hurricane Katrina in 2005, the price of E85 rose to nearly on par with the cost of 87 octane gasoline in many states in the United States, and was for a short time the only fuel available when gasoline was sold out, but within four weeks of Katrina, the price of E85 had fallen once more to a 20% to 35% lower cost than 87 ...
lower octane gas can be sold if labeled as "sub-standard" or "sub-regular" [11] South Dakota: 85/87 87/89 91 85 octane must be sold with a warning label displayed at the pump. [12] 85 and 86 octane can be sold as regular fuel only in the counties of Butte, Custer, Fall River, Harding, Lawrence, Meade, Oglala Lakota, Pennington, and Perkins.
Zimbabwe: 93 octane available with no other grades of fuels available, E10 which is an ethanol blend of fuel at 10% ethanol is available the octane rating however is still to be tested and confirmed but it is assumed that it is around 95 Octane. E85 available from 3 outlets with an octane rating AKI index of between 102 and 105 depending on the ...
The world's top ethanol fuel producer in 2010 was the United States with 13.2 billion U.S. gallons (49.95 billion liters) ... E15 is a higher octane fuel, it is ...
High percentage ethanol mixtures are used in some racing engine applications as the very high octane rating of ethanol is compatible with very high compression ratios. The first production car running entirely on ethanol was the Fiat 147, introduced in 1978 in Brazil by Fiat. Ethanol is commonly made from biomass such as corn or sugarcane.
Both alcohols have a high octane rating, with ethanol at 109 RON (Research Octane Number), 90 MON (Motor Octane Number), (which equates to 99.5 AKI) and methanol at 109 RON, 89 MON (which equates to 99 AKI). [2] Note that AKI refers to 'Anti-Knock Index' which averages the RON and MON ratings (RON+MON)/2, and is used on U.S. gas station pumps ...
