| Abstract: | Based on the mechanisms and principles of diesel engine noise generation, the main factors and improvements for reduction noise were proposed. The noise level of D114 diesel engines were reduced by 3~4 dB(A) with the combination of controlling combustion noise, optimizing block structure, reducing radiated noise of small thickness parts and gear train noise, and adding fan clutch. |
