Effect Of Exhaust Gas Recirculation On Performance And Emission Charecteristics Of Corn Oil Methyl Ester Blended Fuel C.I. Engine

Petroleum diesel consumption increases leads to depleting the diesel fuel and increasing the environmental pollution. One of the alternatives is producing a biodiesel to meet the energy demand. Corn oil methyl ester (COME) is produced by transesterification process and prepared the blends (B0, B20, B40, B60 & B100) with diesel to compare the Engine performance and Emission characteristics with and without exhaust gas recirculation (EGR) at different loads. The result shows the brake thermal efficiency (BTE) and emissions of B20 is almost nearer to diesel. The BTE with EGR is higher than the BTE without EGR for all the blends. The BSFC and EGT with EGR is lower than values obtained without EGR for all the blends. Emissions of CO and HC of engine for all blends are slightly increased, while NOx emissions are found to get decreased with use of EGR. The better engine characteristics were obtained with use of EGR compare to without use of EGR.
