What are the three types of biofuel vehicles?

[DeAllie]

Biofuel vehicles include methanol, ethanol, and dimethyl ether. Taking ethanol vehicles as an example, the following is a detailed introduction to the application methods of ethanol vehicle fuel: 1. Blending method: Ethanol and gasoline are mixed for use. Since no major technical modifications are required for the internal combustion engine and main components of the vehicle, the blending method is the primary method for the promotion and application of ethanol vehicles. 2. Pure burning method: Only ethanol is used as the main vehicle fuel (E85 and above). 3. Denatured fuel ethanol: Ethanol is dehydrated and then mixed with denaturants to produce denatured fuel ethanol, and denatured fuel ethanol vehicles are still in the experimental application stage. 4. Flexible fuel: It can use gasoline, ethanol, methanol, or a mixture of these with gasoline, and can also use hydrogen, with the ability to switch at any time.
