Design and Analysis of Effective Automotive Silencer

Condensation of exhaust gases creates an acidic environment that can damage the car’s exhaust system. Silencers often break down before their time due to corrosion. The current two-wheeler silencer is made of ferrous materials, which corrode in an acidic atmosphere. Material 1, a stainless-steel composite is recommended here as a replacement for mild steel silencers with a wall thickness of 2 mm; Material 2, a glass fiber composite, and Material 3, a carbon fiber composite. In this work, we construct silencers out of a variety of corrosion-resistant materials (Composites) and examine the stresses and strains they experience. After that, we determine the optimal use for each material. We will compare Mild steel, the current material, to the following materials we have chosen. Steel, glass fiber, and carbon fiber are all good examples. These materials were chosen because of their great strength and corrosion resistance. The proposed model employs a computational fluid dynamics (CFD) study with Ansys Fluent for structural analysis to determine the force stand-in on the silencer. FEA is used to study the proposed materials and their effects on the silencer geometry with wall thicknesses of 2, 1, and 0.5 mm. Material 3, with a wall thick of 1 mm in the suggested silencer type, is certainly the safest option.
