Application of Taguchi Method: Design of Experiments for Optimization of Heat Shielding of Two-wheeler Muffler

With rising need for enhanced vehicle performance, muffler designs must address heat dissipation effectively. Utilizing SP’s high thermal resistance and absorbent properties, the study evaluates heat transfer reduction through experimental and computational methodologies. This specific focus allows for a deeper investigation into optimizing heat shielding, a critical aspect of rider safety and muffler efficiency. A full factorial Design of Experiments (DOE) approach and the Taguchi method were employed to optimize material type, thickness, and operating temperatures. This research investigates the effectiveness of various materials and thicknesses of these materials in heat-shielding in two-wheeler mufflers at different temperatures. Results indicate that SP, with an optimal thickness of 2 mm and operating at 200°C, significantly reduces muffler surface temperature, providing a sustainable and efficient solution for two-wheelers. This demonstrates Sodium Polyacrylate’s superior performance compared to traditional materials like aluminized steel and stainless steel, which have higher thermal conductivity and lower temperature thresholds.
