Abstract:The vibration and noise level of marine diesels has big influence on the comfort property of ships, which has been the important index of engine performance as well as power density, volume and weight and so on. The development of identification and separation of noise source,the intake and exhaust noise control technique, the modern prediction method of low noise and new findings of noise control method are presented.Moreover,the status and development trend of noise control technology of internal combustion engines is proposed, which provides reference for technology investigations, product development and system design. |
