Rice Bran Oil-Fueled IC Engine Performance and Emission Characteristics Improved by Nanoadditives

Abstract

In day-to-day life, fossil fuels play an important role in transportation and power generation. The consumption of fossil fuels increasing rapidly with increase in emission from engines. Due to habituation over fossil fuel, both the economy and environment are suffering. The researchers are in the position to find the best alternative for fossil fuels. The employment of biodiesel is taken to be the classy replacement for this snag. According to scores of research, using additions of nanoparticle is the greatest way to control emissions and improve engine performance. Here the assessment was employed though rice bran (RB) oil, rice bran oil blended with aluminum oxide (RB Al2O3), and rice bran oil blended with cerium oxide (RB CeO2). Rice bran oil is extracted and converted into biodiesel by transesterification process. And the nanoadditives are prepared using the two-step method. The addition of nanoadditives showed an improved performance in the engine as well as emission parameters. The congruent assessment clearly demonstrates the improvement of brake thermal efficiency by around 28% for RB-Al2O3 and an improved brake-specific fuel of 16%. Both the blends exhibit good part loading traits.
