Performance, Combustion and Emissions of sunflower methyl esters / diesel blends in Air cooled diesel engine

Abstract In the present circumstance of fossil fuel crisis, the significance of alternative fuel investigates for diesel engines desires no emphasis. sunflower methyl esters can be used as alternative fuels to diesel since their properties are very close to diesel fuel, they are also renewable.Iin the present work, experiments have been carried out to assess the suitability of sunflower methyl esters as fuels in a diesel engine. In the present investigation tests were carried out on a 4.4 KW, single cylinder, direct injection, Air-cooled diesel engine. Sunflower methyl esters used in the present investigation is mixed with diesel with different proportions (B00, B20, B40, B60, B80 and B100) as fuel in the diesel engine. The optimum results were found out from the above investigations and the performance , emissions and combustion analysis are carried out. Different graphs plotted are BP vs SFC, efficiencies, cylinder pressure vs crank angle(p-? diagram) based on the combustion, emissions and performance analysis suitable conclusions are drawn and these results are presented as a paper. Keywords: Diesel Engine, Performance, Combustion, Emissions, Alternative fuel.
