Is VIB gasoline ethanol gasoline?
1 Answers
VIB gasoline is ethanol gasoline. VIB gasoline is a fuel product that meets the China VI-A (Phase 1) standard, which is more environmentally friendly compared to the China V standard fuel. Here is more relevant information: 1. Ethanol gasoline: Ethanol gasoline has very high environmental requirements, is highly susceptible to water, and has a short shelf life. Therefore, the blending, storage, transportation, and sales of ethanol gasoline are much stricter than those of regular gasoline. Generally, small gas stations do not sell ethanol gasoline. Therefore, extra caution is needed when choosing ethanol gasoline, as it may otherwise cause significant trouble for the vehicle. 2. The impact of ethanol gasoline on vehicles: (1) Increased fuel consumption: Since the calorific value of ethanol is about 33% lower than that of gasoline, the energy density of ethanol gasoline is lower compared to pure gasoline of the same volume. With the same fuel tank, ethanol gasoline results in higher fuel consumption. (2) Reduced power performance: Due to the lower calorific value of ethanol gasoline compared to pure gasoline and the higher evaporation temperature of ethanol, the slower vaporization speed during combustion affects the formation of the air-fuel mixture, ultimately leading to a decrease in power. (3) Difficulty in cold starts: Ethanol gasoline has a high latent heat of vaporization and absorbs more heat. During vaporization, it absorbs more heat from the surrounding environment, leading to a decrease in the working temperature inside the engine cylinder and causing difficulty in starting at low temperatures.
