Study of Performance, Combustion and Emission Characteristics of DI Diesel Engine Fuelled with Neem Biodiesel with Carbon Nano Tube as Additive

To tackle one of the major environmental issues concerning modern day mankind, that is air pollution and to reduce dependency on other countries for conventional fuel, finding an alternative fuel is of high priority. Biodiesel is one such alternative. Adding nanoparticles like Carbon nanotubes (CNT) leads to reduction in emissions and enhancement in performance. In this context, in the present paper an experimental investigation was carried out on a computerized single cylinder water cooled diesel engine coupled with an eddy current dynamometer to determine the impact of blending CNT with biodiesel (Neem Oil Methyl Ester or NOME) and a comparative study of various blends using diesel as the baseline was done. The concentration of CNT used were 25 ppm, 50 ppm and 100 ppm CNT blended with B20 biodiesel. The blends were prepared using homogeniser. Readings were recorded for different loads for all the blends and comparative graphs were drawn for performance, combustion and emission characteristics. There was an improvement in the performance characteristics with 8.1% increase in BTE, lowered emissions with 0.0785% decrease in CO and 8.15% decrease in UBHC emissions along with improved combustion relative to diesel when CNT (50 ppm) was added to B20 biodiesel.
