Abstract
AbstractVehicular emissions significantly contribute to environmental pollution, including noise and air pollution. Given the growing population and increasing vehicle usage, mitigating these effects is crucial. This study investigates the efficacy of a modified silencer utilizing asbestos fibres as a noise-absorbing and pollution control material. Experimental tests were conducted on a 100cc Suzuki, four-stroke, petrol engine. The results demonstrate a notable reduction in exhaust frequency (11.3%) and noise level (20%) compared to a conventional silencer, making this modified design a promising solution for commercial applications.Keywords: Noise pollution, Exhaust gas analysis, Modified silencer, Asbestos fibre1. IntroductionThe rapid growth of the global population and increasing reliance on vehicular transportation have led to a significant rise in environmental pollution. Noise pollution, in particular, has become a major concern, with prolonged exposure to high levels of noise leading to adverse health effects. Furthermore, vehicular emissions contribute substantially to air pollution, posing serious risks to both human health and the environment. In response to these challenges, researchers and engineers have been exploring innovative solutions to mitigate the negative impacts of vehicular pollution. One such approach involves the development of modified silencers designed to reduce noise levels and emissions. This study focuses on the design and testing of a modified silencer utilizing asbestos fibres as a noise-absorbing and pollution control material, with the aim of evaluating its efficacy in reducing noise and emissions.
