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 engine are classified based on combustion (ignition), fuel used, cooling, application and constructions. Based on the combustion type : 1. External combustionengines and 2. Internal combustion engines. Based on fuel used : 1. Diesel engines, 2. Petrol engines, 3. CNG engines and LPG engines. Based on cooling system : 1. Air cooled engines and 2. Liquid cooled engines. Based on applications : 1. Statinary engine 2.
