Abstract:

This investigation has the purpose of enhancing both the emission and performance behavior of a 25%Tamarind Oil Methyl Ester blend with diesel (75% Diesel+ 25% Tamarind Oil Methyl ester- TME25). Comparative analysis was done to add different dosages of titanium nanoparticle (TiO₂) at various operating conditions. Various ratios of test fuels were prepared with diesel, TME25, TME25 with 50 ppm of TiO₂ (named TME25T50), and TME25 with 100 ppm TiO₂ (named TME25T100) nanoparticle as additives. The findings of the experimental tests showed that, when related to TME25 without TiO₂ additive, the Brake Specific Fuel Consumption (BSFC) decreased by 8.0% and enhanced the brake thermal efficiency (BTE) by 2.6%. At full power, CO, HC, and smoke emissions have been lowered by 40, 16, and 50%, correspondingly, but NO emissions significantly diminished by 13%. Because TiO₂ improves engine efficiency and combustion, adding it to TME25 raises cylinder pressure and Heat Release Rate (HRR). Finally, it is recommended that a TME25 mixture with 100ppm of TiO₂ nano additive be utilized in diesel engines to advance the combustion characteristics, engine performance and exhaust gas emissions.
