Abstract

Inflation in fuel prices and unprecedented shortage of its supply has promoted the interest in development of the alternative sources for petroleum fuels. In the present study, investigations were carried out on single cylinder, four stroke and water cooled diesel engine. The evaluation of performance, emission and combustion characteristics of sunflower methyl esters blended with diesel fuel were carried out. To characterize the performance at different blending, four blending percentages by volume like 25%, 50%, 75% and 100% were chosen and are named as B25, B50, B75 and B100 respectively. Tests were conducted over entire range of engine operation with varying loads. The engine performance parameters such as specific fuel consumption, brake thermal efficiency, exhaust gas temperature and exhaust emission (CO, CO2, HC, O2 and NOx) were recorded. From the performance characteristics it is noted that, the lower the blend percentage of sunflower methyl esters increases the brake thermal efficiency and reduces the specific fuel consumption. The exhaust gas emissions are reduced with increase in sunflower methyl esters concentration. The experimental results proved that the use of sunflower methyl esters in compression ignition engine is a viable alternative to diesel.
