The feedstock used in our experiment for the production of biodiesel was Yellow Grease. The whole experiment was divided into two parts: Production and Testing. Production involves Transesterification of free fatty acids in yellow grease to form yellow grease alkyl esters. The process of testing involved calculation of the physio – chemical properties, acid value, density, kinematics viscosity and various performance characteristics. The properties obtained were similar to the standards of biodiesel set by ASTM D6751. The conclusions derived from the experiments conducted were that the break thermal efficiency with biodiesel blends was little lower than that of diesel. The break specific energy consumption for B20, B40, B60, B80 and B100 is slightly higher than neat diesel. At all loads, diesel was found to have the lowet exhaust tempearture and the temperature for the different blends showed the upward trend with increasing concentration of biodiesel in the blends.
