What is the difference between unleaded gasoline and ethanol gasoline?
1 Answers
The following are the differences between unleaded gasoline and ethanol gasoline: 1. Different additives: Gasoline is a fraction collected from petroleum, which is a hydrocarbon (mainly alkanes, with a small amount of olefins). It does not contain lead by itself. However, because gasoline is unstable and prone to explosion, lead-containing anti-knock agents were originally added to gasoline. 2. Different levels of pollution: After gasoline is burned, it is discharged from the exhaust pipe, causing certain pollution. Nowadays, gasoline mostly uses unleaded anti-knock agents, which means it is unleaded gasoline. (Most of the 90#, 93#, and 97# gasoline on the market is lead-free). Ethanol gasoline is gasoline mixed with a certain amount of ethanol, approximately 15%. The purpose of this is that ethanol is a renewable energy source and is relatively inexpensive, making its use more economical. This type of gasoline is called ethanol gasoline. (It should be emphasized here that the essence of ethanol gasoline is still gasoline, just containing ethanol).
