THE PERFORMANCE ANALYSIS AND EMISSIONS ANALYSIS OFAN SI ENGINE WITH VARIOUS BLENDS OF ETHANOL- GASOLINE

Abstract

As energy crunch loom large. Fossil fuel stocks are falling. Oil price have broken the $70barrier 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 on ethanol compatible vehicles has increased in recent years with a focus on six areas of importance: the engine, engine control system, cold starting strategy, emissions control, compatible materials, and safety. This major project report is concentrated on high energy content of different ethanol Gasoline Blends E5, E10, E15, E20 and an effort to cover all the other important areas of concern.
