Abstract

The escalating global energy demand and finite fossil fuel reserves necessitate the development of sustainable fuel alternatives for internal combustion engines that also comply with stringent emission standards. Tamarind seed biodiesel presents a renewable option; however, its widespread adoption is challenged by its tendency to elevate nitrogen oxide (NOx) emissions. This research investigates a novel strategy combining magnetite (Fe₃O₄) nanoparticle additives with exhaust gas recirculation (EGR) to optimize the combustion, performance, and emission profiles of a variable compression ratio (VCR) diesel engine. Experimental trials were conducted on a single-cylinder engine utilizing TB20 (20% tamarind biodiesel, 80% diesel) and its nano-enhanced variants, TB20N50 (50 ppm Fe₃O₄) and TB20N100 (100 ppm Fe₃O₄).

The study systematically evaluated engine operation across various loads (0% to 100%) and EGR rates (0%, 10%, 20%). Key findings indicate that the inclusion of Fe₃O₄ nanoparticles significantly improved brake thermal efficiency by 2.61% and reduced specific fuel consumption by 3.34% for TB20N100 compared to TB20. Furthermore, combustion characteristics, including cylinder pressure and heat release rate, showed an increase of 2.5–5% with nanoadditive incorporation, suggesting enhanced fuel utilization and potential for emission mitigation.
