PERFORMANCE AND EMISSION INVESTIGATION ON DI DIESEL ENGINE RUN BY MANGO SEED BIO-DIESEL BLEND WITH NANO PARTICLES

MECHANICAL ENGINEERING

In this study, the bio-diesel was prepared from raw mango seed oil by trans-esterification process subjected to temperature of 650°C. The properties of mango seed oil have been found to be amazingly near to that of petroleum fuels with calorific value 41 MJ/Kg. The bio fuel which is a mixture of diesel and nano particles of bio diesel were prepared and tested in a single cylinder direct injection (DI) diesel engine. The performance and emission characteristics of the engine were under five engine load at the speed of 1500 rpm. Here the Aluminium Oxide is used as an additive to enhance the combustion. The different combination of blends namely (B25, B25+2 ppm of nano particles, B25+4 ppm of nano particles, B25+6 ppm of nano particles) were tested in engine. The results are compared with neat diesel operation. The effect of test fuels on engine Break Specific fuel consumption, Break thermal efficiency, Carbon monoxide (CO), Hydro carbon (HC), and Oxides of Nitrogen (NOx), Emissions was investigated.
