Experimental investigation of Multi Cylinder DI Diesel Engine Fuelled with Dual Bio - Fuels

Abstract: In this experimental study, the performance and emission characteristics were investigated for dual bio fuel (Jatropha oil and Rubber seed oil) in a Multi cylinder diesel engine by retarding the injection timing maintained at standard injection timing of 24?. The blends used in B20 (Biodiesel - 20%), B40 (Biodiesel - 40%), B60 (Biodiesel - 60%) with pure diesel fuel. This paper reveals about the influence of dual bio fuel blends with pure diesel fuel. The performance and emission parameters considered for the tests are SFC (Specific Fuel Consumption), CO (carbon monoxide), NOX (nitrogen oxide) and UHC (unburned hydro carbon). These parameters were analyzed for different load conditions varying from zero to 100 % load. From the test results, it was observed that SFC is lower for B20 blend compared to that of pure diesel fuel whereas B40 and B60 blends have slightly higher values but are closer to B20 blend. It is also found that the emissions of CO, UHC were reduced with increase in blends of biodiesel in the fuel mixture but NOx emission is increased with increase in blends of biodiesel in the fuel mixture.
