内燃机噪声研究的现状与发展

The Current Status and Its Development of Research of Internal Combustion Engine Noise

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。很长时间以来,内燃机工作者在分析内燃机噪声的机理、进行噪声测试和声源识别、研制降噪产品等方面作了大量研究工作。文中将近年来内燃机噪声研究的发展及成果作了简略综述。

The internal-combustion engine produce the strong noise at the time of the work, no matter which kind of occasion it applies, noise reduction is all a very important problem. For a long time, internal-combustion engine researchers make a large amount of work in analyzing noise mechanism of internal-combustion engine, noise testing, noise identification and developing noise reduction product. This text study internal-combustion engine noise in recent years development and achievement of technology and act as a simple survey.
