Experimental Analysis on the Influence of Biofuel Amalgamated Al₂O₃ Nano Particles on the Performance and Emission Attributes of a C.I. Engine

Abstract

With the growing energy demands and the usage of fossil fuels in various energy sectors contributing heavily towards the global warming scenario is of greater concern. With high consumption of the fossil fuels leading to its depletion, alternative and clean energy sources currently play an important role in establishing a cleaner environment while fulfilling the energy demands without affecting the economic growth. Biofuels have emerged as one of the potential alternate energy suitors in today’s time and is starting to find its usability in various sectors including transportation and industries. This paper showcases the production of biofuel from the Madhuca Indica seed oils through the transesterification technique. The paper focusses on the addition of Al₂O₃ nanoadditive on the prepared Madhuca Indica biodiesel blends. Various physiochemical properties were investigated for the prepared biodiesel blends. Experiments were conducted at engine loadings of 0, 25, 50, 75 and 100% to analyse the performance and emission attributes of a C.I. engine accompanied by the utilization of Madhuca Indica biodiesel along with the incorporation of Al₂O₃ nanoadditives to the same. The Al₂O₃ nanoparticle blend B30 MIBD 30 Al₂O₃ and B30MIBD 60 Al₂O₃ were seen to exhibit higher BTE than the primary biodiesel B30 MIBD blend. Lower NO_X emissions were recorded with the 60 ppm Al₂O₃ nanoparticle addition in the test fuels for the entire range of engine load conditions. The inclusion of nanoparticles was seen to illustrate boosted engine performance and curtail emissions.
