Experimental and simulation study to evaluate effect of radial air injection on performance of motorcycle silencers

Abstract

The effectiveness of engine exhaust silencers in reducing noise is crucial for addressing environmental and regulatory concerns. In this study, the effects of radial air injection at pressures of 2, 2.5, and 3 bar on temperature, sound pressure levels, and emissions are assessed to optimize the silencer performance. To investigate this, the study employs ANSYS for detailed 3D modelling of the silencers. This model is then carefully constructed to enable simulation studies to examine the impacts of radial air injection and temperature distribution. Experimental validation is carried out to validate simulation results to verify robustness and reliability. The findings show that three radial air jets effectively reduce carbon monoxide (CO) emissions and temperature. The most promising results are observed at 3 bar of radial air injection, where a temperature reduction of 217 K, a 2.94% decrease in CO emissions, and a 7.84 dB reduction in sound pressure levels are achieved. The agreement between simulation and experimental data demonstrates the potential of radial air injection in improving silencer performance, providing insights for developing more efficient and environmentally friendly exhaust systems.
