Biodiesel is an alternative diesel fuel that can be produced from vegetable oils and animal wastes. Waste chicken fat can be used to produce biodiesel. The performance characteristics of a single cylinder diesel engine is made by using chicken waste biodiesel and blended with diesel fuel. An experimental investigation has been carried out for various blends B20, B40, B60 and the results were compared with diesel fuel. The biodiesel produced from waste chicken fat biodiesel was prepared by a method of transesterification. The effects of biodiesel addition to diesel fuel in the performance, emissions and combustion characteristics of a naturally aspirated DI compression ignition engine are examined. The engine performance was studied in a single cylinder 4-stroke diesel engine set up. Parameters like fuel consumption at different loads for pure diesel fuel and various combinations of blend with diesel fuel. Brake power, brake specific fuel consumption and brake thermal efficiency were calculated and there was a slight increase in performance fueled with different blends. The use of transesterified chicken waste oil can be partially substituted for the diesel fuel at most operating conditions in terms of the performance parameters and emissions without any engine modification.
