K S Babulal , A.Pradeep P.Muthukumar

The present study investigates the performance and emission analysis of Compression Ignition (C.I) engine fuelled with biodiesel and petroleum diesel fuel. The test is done with three fuels namely, petroleum diesel, biodiesel B40 and B100. The engine performance parameters like brake power (BP), brake specific fuel consumption (BSFC), brake thermal efficiency (BTE) and exhaust emission have been studied. BSFC for brake power 0.5 KW with petroleum diesel, B40 and B100 are 0.46 kg / kWh, 0.5 kg / kWh and 0.62 kg / kWh respectively. BTE at full load (3.75 kW) with petroleum diesel, B40 are close to 33 %, but BTE with B100 is about 28 %. NOx with B40 is increased about 2 % when compared to petroleum diesel, whereas with B100 is about 10 %. CO decreased about 20% with B40 and about 50 % with B100. The results conclude that biodiesel mixture of B40 can be the best substitute for petroleum diesel.
