This works about the engine performance and emissions characteristics of NOME biodiesel on diesel engine. Overall, the engine performance of the NOME biodiesel and its blends was only poorer performance than diesel at full load condition. From the view of emissions, NOx emissions were slightly higher in NOME than diesel while un-burnt hydrocarbon emissions were higher for NOME than diesel fuel. The aim of the present work is to prepare Neem oil methyl ester as a diesel fuel substitute. High viscosity and poor volatility are the major limitations of Neem oil for utilization as a fuel in diesel engines. This works discusses the results of investigations carried out on a 4 stroke 4-cylinder, direct injection, diesel engine operated on methyl esters of Neem oil blended with various blend like pure diesel, B05 (Biodiesel 5% and Diesel 95%), B10 (Biodiesel 10% and Diesel 90%), B15 (Biodiesel 15% and Diesel 85%) , B20 (Biodiesel 20% and Diesel 80%) and B100 (100 % Biodiesel).The performance parameters For different NOME blends were found to be very close to diesel and the emission characteristics of engine improved significantly. At maximum load, Brake thermal efficiency of blend B5 (5% biodiesel + 95% mineral diesel) found 34.03 % lower than that of diesel. For B5, brake specific fuel consumption 10.98 Kg/hr. observed was higher than that of diesel at higher load. HC emissions were increased from 2 to 19 for B5 blends as compared to diesel. HC emission were increased when the Neem oil methyl ester proportion were increased.CO emission decrease for different blend of methyl ester of Neem oil and diesel. CO2 emission was increased for the blends of Neem oil methyl ester as compared to diesel.
