为了降低中速四冲程柴油机的噪声,Wartsila进行了长达5年的针对性研究。通过多种措施的结合,可将发动机噪声降低5dB(A)。Wartsila计算和模拟部门的负责人称,解决方案基于外加装置和结构部件的设计改进,而本方案可用于任何原有机型以及正在开发
In order to reduce the noise of the medium-speed four-stroke diesel engine, Wartsila conducted a five-year targeted study. Engine noise can be reduced by 5 dB (A) through a combination of measures. The head of the Wartsila Computing and Simulation division said the solution is based on design enhancements of add-on devices and structural components that can be used with any of the original models and under development
