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 ...
The E85 blend is used in gasoline engines modified to accept such higher concentrations of ethanol, and the fuel injection is regulated through a dedicated sensor, which automatically detects the amount of ethanol in the fuel, allowing to adjust both fuel injection and spark timing accordingly to the actual blend available in the vehicle's tank.
E85 is an ethanol-gasoline fuel mix, usually with a ratio of 85% ethanol to 15% gasoline. The pain at the pump is continuing for drivers as gas prices climb and climb to new records daily. Some ...
In a 2008 study, complex engine controls and increased exhaust gas recirculation allowed a compression ratio of 19.5 with fuels ranging from neat ethanol to E50. Thermal efficiency up to approximately that for a diesel was achieved. [60] This would result in the fuel economy of a neat ethanol vehicle to be about the same as one burning gasoline.
The energy content of ethanol is 76,100 BTU/US gal (5.89 kilowatt-hours per litre), compared to 114,100 BTU/US gal (8.83 kWh/L) for gasoline. (see chart above) A flex-fuel vehicle will experience about 76% of the fuel mileage MPG when using E85 (85% ethanol) products as compared to 100% gasoline. Simple calculations of the BTU values of the ...
Summary of the main ethanol blends used around the world in 2013. Several common ethanol fuel mixtures are in use around the world. The use of pure hydrous or anhydrous ethanol in internal combustion engines (ICEs) is only possible if the engines are designed or modified for that purpose, and used only in automobiles, light-duty trucks and motorcycles.
Some engines, like your high-revving, high-compression Celica engine are able to make better use of the high octane rate of E85 even with their standard motronic, thus reducing consumption a bit - but they should still require ten to twenty percent more fuel than on gas ! If your engine doesn't consume more on E85, it's running lean !
[55] [56] In the US, and based on EPA tests for all 2006 E85 models, the average fuel economy for E85 vehicles was found 25.56% lower than unleaded gasoline. [18] The EPA-rated mileage of current American flex-fuel vehicles [ 57 ] could be considered when making price comparisons, though E85 has octane rating of about 104 and could be used as a ...
