Abstract

The depletion of fossil fuels and the growing concerns over environmental degradation have stimulated research into renewable biofuels as sustainable alternatives to conventional diesel. This study presents an experimental investigation and optimization of a compression ignition (C.I.) engine operated with various biodiesel–diesel blends derived from cottonseed, Jatropha and Neem oils. Experiments were conducted using a single-cylinder, 4-stroke, direct injection (DI), water-cooled diesel engine under varying loads, speeds and blend ratios. The Design of Experiments (DOE) approach was implemented using the Taguchi L9 orthogonal array to evaluate the combined influence of control parameters such as blend ratio, engine load and speed on engine performance indicators—namely Brake Thermal Efficiency (BTE), Brake Specific Fuel Consumption (BSFC) and emission characteristics. Grey Relational Analysis (GRA) was employed for multi-response optimization to identify the ideal operational parameters for maximum efficiency and minimal emissions. Results reveal that a B20 cottonseed biodiesel blend at 195 bar injection pressure provided optimal performance, achieving a peak brake thermal efficiency of 34.01% with reduced specific fuel consumption and smoke density. Comparative analysis with Jatropha and Neem biodiesels confirmed cottonseed biodiesel’s superior trade-off between performance and emission control. The developed mathematical model for thermal efficiency validated experimental results with minimal error, demonstrating the potential of cottonseed biodiesel as a viable renewable substitute for conventional diesel fuel.
