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.
In line with the observations in Japan, hydrous ethanol is known to be less corrosive than anhydrous ethanol. The reaction mechanism is 3 EtOH + Al -> Al(OEt) 3 + 3 ⁄ 2 H 2 at lower-mid blends. When enough water is present in the fuel, aluminum will react preferably with water to produce Al 2 O 3 , repairing the protective aluminum oxide layer.
However, the fuel systems of cars, trucks, and motorcycles sold before the ethanol mandate may suffer substantial damage from the use of 10% ethanol blends. Flexible-fuel cars, trucks, and minivans use gasoline/ethanol blends ranging from pure gasoline up to 85% ethanol . By early 2013 there were around 11 million E85-capable vehicles on U.S ...
For the 2011 model year many of the models available are trucks and sport-utility vehicles that get less than 20 mpg ‑US (12 L/100 km; 24 mpg ‑imp) when filled with gasoline. [22] The following table compares fuel economy, carbon footprint, and petroleum consumption for several popular gasoline-powered vehicles and their flex-fuel versions:
Ethanol production rises to the 4-billion-US-gallon (15,000,000 m 3) level. Between 1997 and 2002, three million U.S. cars and light trucks are produced which could run on E85, a blend of 85% ethanol with 15% gasoline. Almost no gas stations sell this fuel however.
Stellantis’ new Ramcharger pickup, expected to go on sale late next year, will be an “electric” truck, the company says. But really, it’ll be a hybrid, with a gasoline engine under the ...
A high-octane-rated fuel, such as liquefied petroleum gas (LPG), has an overall lower power output at the typical 10:1 compression ratio of an engine design optimized for gasoline fuel. An engine tuned for LPG fuel via higher compression ratios (typically 12:1) improves the power output.
