Investigation on Improvement and Design of Automotive Muffler


Article Preview

Improving design of some automotive muffler is introduced, according to the existing problem of original exhaust muffler in is modified, using sound software attenuation characteristic is analyzed, and pressure distribution of muffler inner is performed to calculate adopting three-dimension flow field tool, and the muffler is tested on engine bench. Result shows that Compared with the original muffler, power loss is decreased by about 30%, set-net noise of the original muffler all has dropped dramatically, and it is in the target.
