一般來說，裝載機產生的排氣噪聲，主要是排氣系統輻射出來的總噪聲，它包括三個方面：一個是管壁的輻射噪聲，一個是消音器壁的輻射噪聲，還有一種是尾管出口的啟動輻射噪聲。
In general, the exhaust noise Shandong loader, is mainly the total noise radiated from the exhaust system, it includes three aspects: one is the radiation noise of the pipe wall, a radiation noise silencer wall, there is a start

radiation noise of tail pipe outlet.  

裝載機產生噪聲的原因，是在裝載機柴油機工作過程中，在排氣閥的地方，氣體流動不穩定，氣流以壓力波動的方式傳到了排氣系統的出口，在尾管出口處，連速度波動產生了不規則噪聲，我們也可以簡單的理解是排氣系統內氣流不穩定引發了排氣噪聲。
Shandong loader noise, is in the loader working process of diesel engine, the exhaust valve in place, gas flow instability, the airflow to the pressure fluctuation of the way to the exhaust system outlet pipe outlet in the tail, even the speed fluctuation produced irregular noise, we can simply understand air exhaust system instability caused exhaust noise.  

裝載機產生輕微的噪聲是正常的，如果一旦產生產生異常的噪聲，必須停機檢查，必要時要找專業維修師傅排查原因。
Shandong loader to produce a slight noise is normal, if there is an abnormal noise, it must be shut down, if necessary, to find a professional maintenance of the cause of the investigation.
