What is one benefit of ethanol when blended with gasoline?

One significant benefit of blending ethanol with gasoline is its ability to help prevent harmful substances in emissions. Ethanol acts as a cleaner-burning fuel that contributes to reducing the levels of carbon monoxide, hydrocarbons, and other emissions associated with conventional gasoline combustion. The presence of ethanol in the fuel mixture can enhance the combustion process, leading to more complete burning and fewer pollutants being released into the atmosphere.

Ethanol is also known for its higher octane rating compared to conventional gasoline. When used in the fuel blend, it helps to improve engine performance by preventing knocking or pinging during combustion, further contributing to overall emission reductions. This cleaner combustion characteristic of ethanol is especially beneficial in meeting regulatory emissions standards, making it a favorable choice for both environmental considerations and engine efficiency.
