发动机排气系统噪声的实验分析
The Experiment Analysis of the Engine Exhausting Noise
【摘要】 以某车型配备491发动机为例,采用实验对发动机上安装和未安装排气系统时的噪声进行了比较,同时得出了在不同频率范围排气噪声对整车噪声的影响。
【Abstract】 In this paper, for an automobile of four- cylinder engine a example, there is a comparison with a engine with exhaust system and non exhaust system in the experimentation. From the result, there are effects on the exhaust system noise for the engine in the different frequency range.
