“…The radical-quenching properties of antioxidants assist to reduce NO x production. 21,25 The antioxidant DPA demonstrated a significant impact on reducing NOx emissions. In the B30 + DPA100 blend, the average NOx emission was lowered by 7.48 and 15.53% compared to base line diesel and the B30 biodiesel blend, respectively.…”

This study aimed to assess the inclusion of antioxidant diphenylamine (DPA) to a Jatropha biodiesel (B30) blend to affects engine performance and exhaust emissions. In this research, three fuel blends has been utilized: diesel, B30, and 100 ppm of antioxidant diphenylamine is added to the B30 blend referred to as B30 + DPA100. A Response Surface Methodology (RSM) has been employed to analyze experimental data, resulting in the development of a regression equation. Additionally, an Adaptive Neuro-Fuzzy Inference System (ANFIS) has been employed to assess and verify the consistency of the developed model. The results from the experiments revealed that the inclusion of the antioxidant had a notable impact on reducing NOx emissions with only a slight effect on brake thermal efficiency (BTHE). Specifically, B30 + DPA100 showed a 7.48 and 15.53% decrease in average NOx emissions, while the average BTHE experienced a modest 0.78% decrease and a 2.67% increase compared to diesel and B30 biodiesel blend, respectively. The Brake Mean Effective Pressure (BMEP) of B30 + DPA100 has been found to be 3.91% and 1.3% higher than diesel and B30, respectively. The Brake Specific Fuel Consumption (BSFC) was 8.68% lower than B30 but 1.49% higher than diesel. Overall, these findings suggest that B30 + DPA100 can be used in diesel engines without modification, offering reduced NOx emissions.

“…Therefore, 15% of the EGR was employed in engine. Yadav et al 25 studied the oxidation stability, performance, and emissions of waste cooking oil biodiesel blends WCO20 with antioxidant DPA, synthetic oxidants TBHQ and PY. DPA has similar oxidation stability to TBHQ, although pyrogallol was better.…”
