Abstract
Biodiesel was prepared from three different individual sources: waste frying oil, palm oil, and castor oil; to compare their performance versus conventional diesel and with respect to each other on the performance of a KUBOTA 67 kW tractor diesel engine. All tested fuels were purely used without any blending. Tractor engine was tested through a P.T.O. hydraulic brake dynamometer at the tractors testing station - Agricultural Engineering Research Institute. Engine performance characteristics and main indicators were determined: P.T.O. torque and power, engine brake power (BP), brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), brake mean effective pressure (BMEP), and air fuel ratio (AFR). The highest performance was achieved by the conventional diesel. The performance of all tested biodiesels were close to each other; and no clear preference of any specific biodiesel could be considered. Their tested properties were also very close. So, the decision of selecting a specific biodiesel (prepared from a specific source) depends mainly on its availability and economical feasibility wherever is used.
