THE PERFORMANCE AND EMISSIONS ANALYSIS OFA MULTI CYLINDER SI ENGINE WITH VARIOUS BLENDS OF ETHANOL-GASOLINE

Abstract

As energy crunch loom large. Fossil fuel stocks are falling. Oil price have broken the $140 barrier par gallon. Many countries are switching to bio-fuels. The EU has decided to use 5.75 % bio fuels like ethanol for motor cars by 2010. China plans to use 10%bio-fuels by 2010. The US already produces about 10 million tones Ethanol. Interestingly, Henry Ford, the father of modern automobile was an ardent advocate of ethanol as a fuel for motor cars. He was a great believer in recycling. Presently we are using 5% ethanol blend with petrol which can be increased to 10%.Brazil is already using 10% ethanol blended with petrol in motor cars which can be increased to 100% ethanol dedicated vehicle. Researchers have shown that the use of high ethanol fuels can results in up to a 66 % reduction of hydrocarbon emissions. Hydrocarbon typically represents 80 % of total vehicle emission. Current vehicle are capable of using E 10, a blend of 90 % gasoline and 10% ethanol. The production and...
