| Abstract |
This report reviews the state-of-the-art for internal combustion engine noise reduction and presents new techniques for reducing engine block vibration and radiated noise. A vibration analysis technique based on measured mobilities was developed as a diagnostic tool for identifying noise sources and vibration transmission paths. This technique makes it possible to identify and rank order the sources of noise within the engine. New design techniques using resilient bearings and modified cylinders liners are also described. |
