ZHANG Zhongdo,ZHOU Houcha,WEI Hua,CHEN Hengbin
Abstract: Aiming at the high noise level at the engine intake port of an extended-range electric bus,the authors design a muffler and optimize its structure through acoustic performance and internal flow field simulations.They ensure that the muffler reduces the noise without affecting the efficiency of the air intake.Finally,they validate the muffler's noise reduction effectiveness through experiment.
Key words: extended-range electric bus; intake port noise; muffle
