What is the difference between ethanol gasoline and unleaded gasoline?

[VonEmmett]

The differences between ethanol gasoline and unleaded gasoline: 1. Price difference: Ethanol gasoline is generally cheaper, as the proportion of gasoline is reduced, and this low-cost alcohol replaces part of the gasoline. 2. The heat of combustion of ethanol gasoline is lower than that of gasoline: Therefore, using ethanol gasoline may make the car feel less powerful. 3. The same tank of fuel will yield different mileage: A tank of unleaded gasoline can run 600 kilometers, while a tank of ethanol gasoline can only run 570 kilometers. Advantages of ethanol gasoline: 1. High octane number and good anti-knock performance. 2. Ethanol has an oxygen content of up to 34.7%. Adding 10% ethanol to gasoline can achieve an oxygen content of 3.5%. 3. The use of ethanol gasoline in vehicles can effectively reduce vehicle exhaust emissions and improve the energy structure.
