At 0.5 kW load the BSFC for diesel and karanj oil was 889.41 and 1037.28 g/kW.h respectively. While at full load (3.7 kW), the BSFC was 320.50 g/kW.h and 648.01 g/kW.h for diesel and karanj oil respectively. The BSFC of the blends varied in between, depending upon the percentage of diesel in blend. The BSFC for karanj oil and its blends was greater due to the fact that it has lower heating value than diesel. To generate the same amount of power, more quantity was required. The BSFC of all the test fuels was least near full load.
