Abstract. This study explores the use of biogas and nanoparticle-doped biodiesel as sustainable options for compression-ignition (CI) engines, driven by worries about the depletion of fossil fuels and their environmental effect. This study provides a complete overview of the interconnected impacts of engine load, nickel oxide nanoparticle doping rate, Neem biodiesel mix ratio, and biogas flow rate on the performance and emissions of a CI engine. Response Surface Methodology (RSM) provides a means to comprehend and conduct organized experiments, while Artificial Neural Network (ANN) is capable of capturing intricate non-linear interactions. Both models undergo thorough statistical analysis utilizing several assessment metrics to reveal the impact of each input parameter on important outcomes. This study also extensively explores the important field of optimization, focusing on the progress achieved in RSM and ANN models. RSM’s desirability function optimized the output parameters at 67.45% engine load, 96.06 ppm NDR, 10.7 % BBR and 0.85 kg/h BFR, while ANN with Harris Hawks Optimization (HHO) optimized the output parameters at 67.01% engine load, 98.39 ppm NDR, 8.41% BBR and 0.846 kg/h BFR. This integrated approach offers a robust framework for enhancing the sustainability and efficiency of CI engines, presenting practical solutions for transitioning toward cleaner energy systems.
