内燃机噪声源识别与噪声控制技术研究

Study of Noise Source Identification and Noise Control of IC Engine

内燃机工作时产生强烈的噪声,无论其应用于何种场合,降噪都是一个很重要的问题。本文着重剖析了用于内燃机噪声源识别的各种方法,并分别从燃烧噪声、机械噪声、进排气噪声和风扇噪声等方面进行了分析并提出了具体的解决措施。

The internal-combustion engine produces the strong noise during work, no matter on which kind of occasion it applies, noise reduction is all a very important problem. A variety of methods for noise source identification are expounded with emphases in this paper. Measures are put forward after analysis of noises from combustion, mechanics, intake and exhaust and fan, etc.
