The use of ethanol in cars can increase the octane number of the fuel, increase the oxygen content, make the combustion in the car cylinder more complete, and reduce the emission of harmful substances in the exhaust gas.
Fuel application methods of ethanol vehicles: 1. Blending, which refers to the blending application of ethanol and gasoline. In the mixed fuel, the ratio of ethanol to volume is represented by "E". If ethanol accounts for 10% and 15%, it is represented by E10 and E15. At present, blended combustion accounts for the majority of ethanol vehicles. 2. Pure burning, that is, single burning ethanol, which can be expressed by E100%. It is currently not widely used and belongs to the trial stage; 3. Denatured fuel ethanol refers to ethanol produced by adding a denaturant after ethanol is dehydrated. This is also a test application Step; Fourth, flexible fuel means that the fuel can be gasoline, ethanol or methanol mixed with gasoline, or hydrogen, and can be switched at any time. For example, Ford and Toyota are experimenting with flexible fuel vehicles (FFV).
