What is the difference between ethanol gasoline and regular gasoline?
2 Answers
Ethanol gasoline and regular gasoline differ in performance: the ethanol in ethanol gasoline is a renewable resource, produced through fermentation of crops such as sorghum, corn, and potatoes, making it more environmentally friendly; gasoline, on the other hand, is non-renewable and emits more polluting gases. Ethanol gasoline is an alternative fuel formed by blending fuel ethanol, processed from grains and various plant fibers, with regular gasoline in a specific ratio. According to China's national standards, ethanol gasoline consists of 90% regular gasoline and 10% fuel ethanol, creating a mixture. Adding an appropriate amount of ethanol to gasoline as a vehicle fuel can help conserve petroleum resources and reduce air pollution from vehicle emissions.
I've been paying attention to environmental topics and think the biggest difference between ethanol gasoline and regular gasoline lies in their environmental impact. Ethanol gasoline blends about 10% ethanol, which comes from crops like corn, making it more renewable and releasing less carbon dioxide when burned, thus being more eco-friendly. However, the drawbacks are also evident. Pure gasoline has higher energy density, so ethanol gasoline may slightly reduce driving range and could be less fuel-efficient, especially during long-distance trips. I've also noticed that ethanol gasoline tends to absorb moisture in humid areas, potentially causing engine issues. But overall, to reduce carbon footprints, many regions are promoting its use, and I'm willing to choose it, particularly for urban commuting.
