This chapter focuses on enhancing the performance, combustion, and emission characteristics of a novel biodiesel blend-a mix of diesel (80%) and tamarind seed oil (20%), represented as tamarind seed methyl ester (TSME) with alumina oxide (Al2O3), Carbon nano tubes (CNT), and Cerium oxide(CeO2) considered as potential nanoparticles. These were added to TSME at concentration of 50 ppm and were uniformly dispersed in the biodiesel blend with the help of a magnetic stirrer as well as an Ultrasonicator to attain stable suspension. The immersed nanoparticles in the tamarind seed oil blend exhibit multiple advantages such as an enhanced air-fuel mixing, better oxidation process, larger surface area to volume ratio results in higher brake thermal efficiency, as well as a significant reduction in smoke opacity, hydrocarbon, and carbon monoxide emissions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
