EMISSION TEST ON S.I ENGINE USING ALTERNATIVE FUELS AND ETHANOL

The uses of automobiles are increasing day by day and increased Air pollution. Increasing global concern due to air pollution has generated much interest in the environmental friendly alternative fuels. Alternative fuels for IC engines are also becoming important because of diminishing gasoline reserves and increasing air pollution. Also one of method to use tri-fuels (Petrol and Kerosene) with additives of ignition in combustion chamber improves the rate of combustion and reduce the Air pollution. The Air-fuel mixture gets ignited and the flame travel for complete combustion in the chamber. The emission outcomes phenomena are to be analyzed and also efficiency of the engine checked by constructing the load test method. Ethanol is good candidates as alternative fuel. In this study, the effect of ethanol fuel blends and spark plugs ignition are investigated on 2- stroke single cylinder SI engine for analyzing the performance and combustion characteristics. The tests were performed using an electric dynamometer while running the engine and different load conditions. Exhaust gases namely, carbon dioxides (CO2), carbon monoxide (CO2) and unburned hydrocarbons (HC) are measured using multi exhaust gas analyzer. Exhausts emissions of the fuels is founded.
