摘要
发动机整机噪声主要包括燃烧噪声和机械噪声,其影响因素很多。以某型号发动机为例进行试验,探讨了改变凸轮轴型线以及性能参数对发动机噪声的影响。
Engine noise mainly includes combustion noise and mechanical noise.And there are many factors that affect it.Taking a certain type of engine as an example to carry on experiment, influence of changing cam shaft line and performance parameters on engine noise was discussed.
