In this research work prospects and opportunities of utilizing 100% biodiesel and increasing biodiesel-diesel blend ratio as fuel in diesel engine has been investigated by varying compression ratio. The properties of these were compared with the characteristics required for internal combustion engine fuels specially diesel engine. Experiments were performed for three compression ratio i.e.14,16 and 18 using biodiesel diesel blends i.e. B20, B30, B40, B60, B80 and pure biodiesel with load variation from no load to full load and compared with base cases i.e. engine using diesel as a fuel. Biodiesel was prepared from the raw honge oil (jatropha oil) by the trans-esterification process. The kinematic viscosity of the biofuel was found several times greater than that of diesel. This higher viscosity value of biofuel 7.12 mm²/s as compared to 4.5 mm²/s for diesel at 40°C leads to many problems in pumping, atomization and others that necessitated the trans-esterification process. Further investigations are made to study the sole effect of the use of the blends of PPME and diesel in diesel engines. The experiments are conducted in a diesel engine coupled with an exhaust gas analyzer to study the performance characteristics and the extent to which the jatropha oil could replace diesel.
