摘要
某车型排气声品质有2个方面的问题:在加速时具有明显的排气气流噪声,且怠速时的排气"突突"声较大。针对这两个问题,文章对排气消声器进行优化设计。优化后的排气结构成功地解决了加速气流声和怠速"突突"声,提高了排气声品质。
There are two sound quality vious flow noise at accelerating, another one is resolve these two problems. The flow noise at solved after exhaust muffler optimization. And problems of exhaust system for one vehicle ： pupu＇noise at idle. The exhaust muffler is o One is ob- ptimized to accelerating and ~pupu ~ noise at idle are successfully the exhaust system sound quality is improved.
