摘要

The growing demand for sustainable and cleaner alternatives to fossil fuels has intensified research into biodiesel-based fuels and emission control strategies. This study investigates the combined effects of magnetite (Fe₃O₄) nanoparticles (NPs) and exhaust gas recirculation (EGR) on the performance, combustion, and emissions of a single-cylinder diesel engine fueled with tamarind biodiesel. Tamarind biodiesel was produced via transesterification and blended with diesel in a 20% ratio (TB20). Magnetite NPs with an average particle size of 50 nm were dispersed in a TB20 blend at a dosage of 50 ppm using an ultrasonicator. Engine tests were performed under different load conditions and EGR rates of 0, 10, and 20%. Results showed that the addition of Fe₃O₄ NPs improved brake thermal efficiency (BTE) by 4.47% relative to the baseline TB20 fuel without nanoparticles, along with significant reductions in carbon monoxide (CO), hydrocarbons (HC), and smoke emissions compared to TB20 alone. However, increasing EGR rates led to a reduction in BTE by 2.65% and 6.03% at 10% and 20% EGR, respectively. In contrast, NOx emissions were significantly reduce, with a maximum decrease of 52.9% at 20% EGR compared to the 0% EGR condition for the same nanoblend fuel. Additionally, artificial neural network (ANN) models have been used to forecast engine performance and emissions, demonstrating high R² values ranging from 0.98743 to 0.9995 and MAPE values ranging from 1.4448 to 6.5075. The study concluded that a 10% EGR rate combined with the nanoblend offers an optimal balance of enhanced performance and reduced emissions compared with the TB20 blend, making it a promising approach for cleaner diesel engine operation.
