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.
Internal combustion engine. The internal combustion engine is a heat engine in which combustion occurs in a confined space called a combustion chamber. Combustion of a fuel creates high temperature/pressure gases, which are permitted to expand. The expanding gases are used to directly move a piston, turbine blades, rotor(s), or the engine itself thus doing useful work. Internal combustion engines can be powered by any fuel that can be combined with an oxidizer in the chamber.
