Abstract
Majority of the automobiles run with internal combustion engines such as spark ignition (SI) and compression ignition (CI) engines which use conventional fuels such as Petrol, Diesel etc. The use of automobiles increasing day by day in the human life .As the use of the automobiles increase, the consumption of the fuels like petrol, diesel also increases and due to the increased consumption of the fuels depletion of fuel resources occurs. Along with the depletion the emissions emitted from the automobile engines increases and there by affect human health, and environment. The main emissions like hydrocarbons(HC) , carbon monoxide (CO) ,nitrogen oxides(NOx) and oxides of sulphur (SOx) emitted from automobile engines affect human lungs and also affects the environment which causes global warming and acid rains. From the above reasons in order to reduce the emissions various researches going on petrol and diesel engines. The petrol engines are used in light weight motor vehicles where as diesel engine are used in heavy duty motor vehicles. The petrol engines are very popular from the time of their invention; most of the automobiles are run by these engines mainly because of its simplicity and ease of operations, they are the choice for number of researches. As crude oil reserves are decreasing and increasing price of petrol alternative fuels are coming in to picture. Now a day’s most of the alternative fuels like ethanol, methanol, orange oil, eucalyptus oil are biomass derived and easily available. Alternative fuels which are renewable and also eco friendly reduce the dependency on fossil fuels and they help to preserve the atmosphere by reducing the emission levels. Alternate fuels can be in the form of solid, liquid, and gaseous fom. The solid fuels are not used in ic engines due to their physical properties, the liquid fuels are alcohols (ethanol, methanol) and vegetable oils (edible and non edible), and the gaseous fuels are LPG, CNG, H2, biomass and producer gas. Liquid fuels are easy to handle and calorific value of these types of fuels is more.. Many alternative fuels blends has been introduced in past and they gave satisfying results. Therefore, in this project the eucalyptus oil which is high octane biomass derived fuel is blended with petrol 15% by volume that is Eu15 and used as fuel in four stroke multi cylinder petrol engine and pollution characteristics were studied and analyzed using ANSYS-FLUENT software
