Does New Energy Gasoline Harm Vehicles?
2 Answers
Harmful to vehicles. Such as ethanol. The specific manifestations of new energy gasoline harming vehicles are as follows: 1. Affects starting and operation: Ethanol gasoline has a higher latent heat of evaporation, approximately more than twice that of regular gasoline. This results in vaporized ethanol gasoline absorbing more heat than regular gasoline after entering the cylinder and evaporating. Consequently, vehicles using ethanol gasoline face relatively more difficulty starting in extremely cold climates and require longer warm-up times. The key issue, however, is that ethanol gasoline is primarily promoted in cold northern regions, which is inevitably unacceptable to northern vehicle owners. 2. More noticeable corrosion: After combustion, ethanol not only produces water and carbon dioxide but also acetic acid, which corrodes automotive metals, especially copper. This corrosion becomes more pronounced when the ethanol content in gasoline exceeds 15%. 3. Prone to deterioration and engine damage: Domestic ethanol gasoline is susceptible to deterioration, leading to oil-water separation when left unused for extended periods, which is undoubtedly fatal to automotive engines. 4. Increases fuel consumption: Ethanol cleans the dirt (mainly a mixture of gum and rust) from the fuel tank and pipelines and sends it to the cylinder. Domestic ethanol gasoline is a blend of base gasoline and ethanol. Due to process issues, domestic base oil contains significant amounts of gum and sulfur, leading to increased accumulation of dirt and gum in the intake system or on the fuel injectors. This results in decreased engine combustion efficiency and increased fuel consumption.
Lately, I've been frequently asked about ethanol-blended gasoline. Having driven for twenty years and used all kinds of fuels, I don't think it's particularly harmful to cars. Modern vehicles are designed with the characteristics of ethanol-blended fuel in mind from the factory, especially new cars which are fully compatible. However, older cars require some caution, particularly when left unused for extended periods. Ethanol tends to absorb moisture, which can make the fuel tank damp and potentially clog fuel injectors over time. I always make sure to check the fuel grade before filling up and avoid mixing different brands. In winter, ethanol-blended fuel is less prone to freezing, while in summer, its faster evaporation rate is actually convenient. I recommend adding a fuel system cleaner every six months and avoiding overly aggressive driving. Generally speaking, there shouldn't be any major issues.
