Experimental investigation on the performance of CI engine using dual biodiesel

In this present work focused on combination of two different biodiesel blends with diesel. The present study brings out an experiment of two bio diesels from jatropha oil (B20J), Mahua oil (B20M) and Dual biodiesel(B10M+B10J) they are blended with diesel. The effects of dual biodiesel works in engine and exhaust emissions were examined in a single cylinder, direct injection, air cooled and high speed diesel engine at various engine loads with constant engine speed of 1500 rpm. Results showed that at full load conditions the brake thermal efficiency B20J is higher than other blends. BSFC lowest for diesel compare to other blends. The emissions of CO and HC of dual biodiesel are lower than that of diesel. But NOx is higher in dual biodiesel compare diesel.
