PROTON SATRIA MAIN MUFFLER DEVELOPMENT FOR EUROPE HOMOLOGATION PASS BY NOISE TESTS
Keywords:
KeywordsAbstract
A pass by test was carried out on Satria Gti to fu lfill some regulation requirements before the car is sold to Europe. Three sources ofnoise were identified and noise ranking method was used to identify the highest contr ibution of noise level. The exhaust system was identified as the main source and a modified main mujjle r lVas developed and fabricated which successfully reduced noise level below 74 dB(A).
