Abstracts: In world, day by day utilization of fossil fuel increases and environment climate change rapidly. they lead to development of eco-friendly alternative fuel.we are performing the experiment on four stroke diesel engine with different blends (B5,B10,B15,B20) of neem oil and diesel as various loads and the result show that BTE of all blend slightly higher than diesel at all load as well as BSFC is lower for all blend than diesel, it has been established that up to 20% of neem oil biodiesel can be use as a substitute for diesel without any engine modification thus neem oil as non-edible oil can be a good renewable raw material for biodiesel production. The engine power and pollutant emissions characteristics under different biodiesel percentages were also studied. Our experiments show that the biodiesel produced using neem oil could have lower CO2 and HC emission for B5 and B15 than diesel but slightly higher Carbon monoxide emissions. Thus, the ester of this oil can be used as environment friendly alternative fuel for diesel engine.
