What is the impact of ethanol gasoline on cars?

[VonGemma]

Ethanol gasoline has the following impacts on cars: 1. Reduced power performance. Since ethanol gasoline has a lower calorific value than pure gasoline and a higher evaporation temperature, its slower vaporization during combustion affects the formation of the air-fuel mixture, ultimately leading to decreased power output. 2. Difficulty in cold starts. Ethanol gasoline has a high latent heat of vaporization and absorbs more heat. During vaporization, it absorbs a significant amount of heat from the surrounding environment, which lowers the working temperature inside the engine cylinder, making it harder to start in cold conditions. 3. Cleaning effect: Ethanol gasoline not only reduces vehicle emissions but also has excellent cleaning properties. It effectively removes deposits and condensation of fuel impurities in the fuel tank and fuel system, particularly phenomena like gum formation, providing good fuel system cleaning and unclogging effects.
