A noise reduction technique in internal combustion engines: A multidisciplinary approach

This research paper delves into the various noise reduction techniques employed in internal combustion engines (ICE), highlighting the multidisciplinary approach needed to address this complex issue. By combining mechanical engineering, materials science, and acoustic engineering, the study investigates both traditional and innovative methods to mitigate engine noise. Key sources of noise, including combustion, mechanical, flow-induced, and structural vibrations, are analyzed. The paper further explores advanced materials such as sound-absorbing compounds, lightweight alloys, and smart materials, as well as novel design approaches, including computational fluid dynamics (CFD) and structural optimization. Active noise control systems are examined as a cutting-edge solution. The integration of these techniques into modern engine design, while balancing efficiency and performance, is crucial for meeting regulatory standards and improving user comfort. The paper aims to provide a comprehensive review of current technologies and future prospects for noise reduction in internal combustion engines.
