Abstract: Prosopis juliflora methyl ester (PJME) was produced from a non edible feedstock found in the arid and semi-arid regions all over the globe. The Biodiesel from this species was produced with respect to optimum transesterification process variables. An experimental investigation was done using the Methyl ester in a DI diesel engine to estimate the performance, combustion and emission characteristics at a brake power of 5.2 KW and an unvarying speed of 1500 rpm. Experimental studies on the methyl ester revealed that there was a decrease in the brake thermal efficiency by 8.34 % and increase in the emission of Carbon monoxide (CO), unburnt hydrocarbon (HC) and smoke by 10.7 %, 16 % and 11 %, respectively. PJME exhibited NOx emission of 10.71 %, lower heat release rate (HRR) of 23 %, and 7 % peak pressure when compared to neat diesel under 100 % loading condition. From the successive experiments conducted with Prosopis juliflora methyl ester, B20 Biodiesel blend was found the best suitable blend for marine engines as the results almost matches with the neat diesel. Also, biodiesel from this non edible species proved that it was an inherent source for alternative fuel, with environmental benefits.
