Ethanol, an alcohol fuel, is an important fuel for the operation of internal combustion engines that are used in cars, trucks, and other kinds of machinery. 1  Ethanol was first isolated from wine in approximately 1100 and was found to burn shortly thereafter. Ethanol production rises to the 4-billion-US-gallon (15,000,000 m 3) level. 2  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.
Engine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work.There are two classifications of thermal engines-. 1  Internal combustion (gasoline, diesel and gas turbine, i.e., Brayton cycle engines) and.2  External combustion engines (steam piston, steam turbine, and the Stirling cycle engine).ngine efficiency of thermal engines is the relationship between the total energy contained in the fuel, and the amount of energy used to perform useful work.
