Performance And Emission Characteristic of Single Cylinder CI Engine Using Fish Oil as a Bio diesel with Varying injection Pressure

The latest biodiesel research in India obtains its attention towards fish-oil based biodiesel. In this work, biodiesel obtained from the fish-oil extracted from fish types was used as fuel in diesel engine to investigate its performance and emission characteristics of unmodified common-rail diesel engine operating with biodiesel. The different blends of fish-oil biodiesel with diesel, B20, B40, B60, B80 and B100 were used in the experiments and the results shows that brake specific fuel consumption (BSFC) and brake thermal efficiency (BTE) were higher with B100 fuel than that of diesel. The exhaust gas temperatures of B100 were lesser than that of diesel at the different loads. At full load, B100 fuel produced higher smoke, CO in %, HC in ppm, CO2 in %volume and NOx in ppm emissions of 0.28%, 8ppm, 4.03%, and 462ppm respectively with reference to diesel fuel. The present research work is meant to examine experimentally the recital and exhaust emission characteristics of a diesel engine fuelled with conventional diesel 0fuel, fish oil biodiesel and the blends of diesel-biodiesel in different percent volumes over the entire range of load.
