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.
The External Combustion Engine is a more efficient variant of the internal combustion engine. The External Combustion Engine was first created in the early 1920s. Because it was introduced after Internal Combustion Engines had become the norm, it was widely ignored for much of the 20th century.
