What are the advantages of Ethanol blending in fuels ?
Ethanol blending is a process of blending ethanol with petrol. Ethanol is obtained from sugar industries which is a by-product of sugarcane molasses. Ethanol blending was started in India in 2001. Ethanol blending reduces carbon monoxide and carbon-dioxide emissions up-to 30%, cleans the car engine and dirt from pipes and chambers. It also acts as an anti-knocking agent results in decreasing engine knocking. Comparing with petrol ethanol burns cleaner and completely. 5% of ethanol blending replaces a large amount of crude oil. Till 2017 5% of mixing Ethanol was allowed in India now it’s increased to 20%. Few countries like U.S. blending is allowed up to 10%.
Ethanol has a higher octane number than gasoline, which provides increased performance and power. For example, Indianapolis 400 drivers often fuel their race cars with E98 because of its high octane. There are currently projects underway, including the Co-Optimization of Fuels and Engines initiative, to understand the potential for improving engine efficiency through the use of it’s blends and other high-octane biofuels.
