Abstract—In the present investigation, experimental work has been carried out to analyze the emission and performance characteristics of a single cylinder 3.7 kW, compression ignition engine fuelled with mineral diesel and biodiesel blends at an injection pressure of 200 bar. Methyl ester of Pongamia (PME), Jatropha (JME) and Neem (NME) were derived through transesterification process. Experimental investigations have been carried out to examine Properties, Performance and Emissions of different blends (B10, B20, B40 and B100) of PME, JME and NME in comparison to diesel. Results indicated that B20 have closer performance to diesel and B100 had lower brake thermal efficiency mainly due to its high viscosity compared to diesel. However, its diesel blends showed reasonable efficiencies, lower smoke, CO, HC and higher NOx emissions. Pongamia methyl ester gave better performance compared to Jatropha and Neem methyl esters.
