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.

Present Experimentation

The present experimentation is carried out on a diesel engine using biodiesel as a fuel. The combination of lemongrass and tamarind seed methyl ester has replaced the diesel at various percentages. This investigation used three blends of biodiesels i.e. 10% of mixed methyl ester and 90% of pure diesel (B10) similarly B20, and B30. From the obtained results it was observed the enhanced brake thermal efficiency (BTE) for biodiesel blends as compared to the diesel. The blend B20 shows enhanced BTE than other samples, being around 20% higher than the diesel. The biodiesel blends show a reduction in HC and CO emissions and enhancement in CO2 and NOX emissions than the diesel. The highest heat release rate observed for B20 at a crank angle of 355° is 68.77 J/deg.

Ignition Delay Period

In this study, different characteristics of sustainable renewable biodiesels (those have a high potential of their production worldwide and in India) were compared with the characteristics of neat diesel to determine optimistic biodiesel for the diesel engine at 250 bar spray pressure. Optimistic fuel gives a comparatively lower level of emissions and better performance than other selected fuels in the study. Rubber seed oil methyl ester was investigated as an optimistic fuel among the other selected fuels such as sunflower oil methyl ester, neem seed oil methyl ester, and neat diesel. To enhance the performance characteristics and to further decrease the level of emission characteristics of fuel ROME, further experiments were conducted at higher spray (injection) pressures of 500 bar, 625 bar, and 750 bar with varying ignition delay period via varying its spray timings such as 8°, 13°, 18°, 23°, 28°, and 33° before top dead center. Spray pressure 250 bar at 23° before top dead center was investigated as an optimistic operating condition where fuel rubber seed oil methyl ester gives negligible hydrocarbon emissions (0.019 g/kW h) while its nitrogen oxide (NOX) emissions were about 70% lesser than those observed with neat diesel, respectively.
