THE PERFORMANCE ANALYSIS OF AN SI ENGINE WITH VARIOUS BLENDS OF ETHANOL - GASOLINE

Abstract

As energy crunch loom large. Fossil fuel stocks are falling. Oil price have broken the $70 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. Research has shown that the use of high ethanol content fuels can result in up to a 66% reduction of hydrocarbon emissions. Hydrocarbons typically represent 80% of total vehicle emissions. Current vehicles are capable of using E10, a blend of 90% gasoline and 10% ethanol. The production and research o...
