Biodiesel blends were tested under various EGR rates (5%, 10%, and 15%) to analyze key performance parameters such as brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), and emissions including nitrogen oxides (NOx), carbon monoxide (CO), unburned hydrocarbons (HC), and particulate matter. To effectively model the nonlinear behavior of the engine system, a fuzzy logic-based approach was employed. The fuzzy logic model (FLM) was developed using inputs such as engine load, EGR rate, and biodiesel blend ratio, with outputs being engine performance and emission indices. Experimental results indicated that moderate EGR rates significantly reduced NOx emissions, though with slight reductions in thermal efficiency and increases in BSFC. The fuzzy model accurately predicted engine responses, demonstrating its suitability for decision-making and optimization in dual-fuel, EGR-assisted diesel engine systems. The integration of biodiesel and fuzzy-controlled EGR offers a promising approach to achieving cleaner combustion while maintaining acceptable engine performance. |
