Experimantal performance analysis of biodisel,traditional diesel and biodiesel with glycerine

Biodiesel, traditional diesel and biodiesel with glycerine were used as the fuel of a direct injection compression ignition engine. The torque, brake power and fuel consumption values associated with these fuels were determined under certain operating conditions. Effective efficiency, effective pressure and SFC values were calculated according to the formulae given in the Appendix. The obtained results were compared and it was noted that all fuels yielded similar results at some points. However, biodiesel and biodiesel with glycerine gave different values under the same conditions. According to these results, glycerine affects engine performance under certain engine speed conditions.
