Ethanol is commonly known as alcohol. In layman's terms, cars that use ethanol as fuel can also be called alcohol cars. The use of ethanol to replace petroleum fuels has a long history. Both production and application technologies have been mature. Recently, due to the shortage of petroleum resources, the diversification of automobile energy has intensified, and ethanol cars have been on the agenda.
At present, there are more than 40 countries in the world that use ethanol vehicles to varying degrees, and some have reached a large-scale promotion, and the status of ethanol vehicles is increasing.
