1, different features: ethanol gasoline uses fuel ethanol as gasoline additive, which is environmentally friendly, clean and renewable. However, ordinary automobile gasoline uses chemical agent MTBE as gasoline additive, which has great pollution to the environment. Many countries have successively banned MTBE and other additives.

2. Different evaporation potential: ethanol has a greater evaporation potential, which is twice that of gasoline. This characteristic can improve the thermal efficiency of the engine and the favorable factors for cooling the engine.
