Abstract: In this present work, biodiesel is produced from a new feedstock; Custard apple seed oil using hydrodynamic cavitation (HC), ultrasonic cavitation (UC) and conventional mechanical stirring (MS) methods via transesterification under optimum conditions: oil to methanol ratio, 1:6, in the presence of 0.75 wt.% potassium hydroxide as catalyst and 60°C operating temperature. Further, various test fuels were prepared for the engine tests by blending 20%, 40%, 60%, 80%, and 100% of Custard apple methyl ester (CAME) in diesel on volumetric basis and labelled as B20, B40, B60, B80 and B100, respectively. The BTE, in general, was found to be decreased and BSFC increased with increased volume fraction of CAME in the blends. At higher load conditions, smoke emissions were found lower for all CAME blends in comparison to pure diesel. Thus, Custard Apple seed biodiesel can become an alternative fuel in the future.
