Performance and Emission Characteristics of Four Stroke Diesel Engine Using Methyl Ester of Nerium Oil with Ethanol Fuel

S. Prabhakar, V.N. Banugopan, K. Annamalai


The major fuel used for commercial vehicles in India is the diesel fuel. This is non- renewable fuel is also depleting oil resource. Diesel is well suit for the commercial transportation purpose compare to the other fuel including gasoline. Thus the various blends are used, as it is same as that of diesel properties. In this direction, an attempt has been made to investigate the performance, combustion and emission characteristics of esterifies Nerium oil mixed with ethanol. The fuels considered are 5%, 10%, 15%, 20% of ethanol (biodiesel) blended with 95%, 90%, 85%, 80% esterifies nerium oil oil. The results derived from the test shows that Nerium oil mixed with ethanol has a kin performance characteristics as that of diesel and better emission characteristics. Hence bio-fuels of Nerium oil mixed with ethanol can replace the diesel without compromise in engine performance. At present neither Nerium oil nor bio-diesel of Nerium oil is available in the market. Hence for our work, well grown Nerium seeds are collected from different parts of Tamil Nadu (India). Then after proper filtration, esters of Nerium oil are prepared using the bio-diesel plant available in the department.
