| Abstract: | In order to achieve the dual function of exhaust purification and exhaust noise reduction for diesel engines, an integrated exhaust purification muffler is designed and analyzed. The finite element model of the muffler is established and the sound field characteristic is simulated by means of sound field analysis software Virtual Lab. The impact of the exhaust flow rate, temperature, outlet pipe reflection, intubation and cellular carrier on the muffler’s performance are investigated. The design of the integrated exhaust purification muffler is verified to be reasonable. |
