| description | This study investigates the characteristics of combustion noise generation in a diesel engine under running condition using wavelet transformation and transient combustion-noise-generation model. The results show that combustion noise largely contributed to the total engine noise in the early stage of the expansion stroke. Maximum combustion impact energy had a predominant effect on maximum combustion noise power and therefore on maximum engine noise power for each cycle. The combustion noise power exponentially decayed with time. The duration of combustion noise depends mainly on the maximum combustion noise power, which is controlled by the maximum combustion impact energy and transmission-radiation rate. |
