| Abstract: | To evaluate the radiated noise level and to analyze the influence of diesel engine performance on its overall radiated noise are important technical approaches for low noise diesel engine design. This paper takes a high power marine high speed diesel engine as the example to elaborate the evaluation method of diesel engine structural noise and analyzes its overall radiated noise under different working conditions. |
