当发动机空气滤清器被沙尘堵塞到不能满足发动机工作时所需要的空气体积流率时,会出现下列情景: 1.轰鸣声发闷。这是因为燃油燃烧过程中缺氧,延长了燃烧时间,工作压力下降,排气门开启瞬间的压差偏小所造成。 2.加速时反应迟缓。这是因为进气量不足,工作行程的爆燃压力不够以致功率增量太少引起的。
When the engine air cleaner is clogged with dust and can not meet the required air volume flow rate when the engine is working, the following scenario will appear: 1. Roar sound boring. This is because the oxygen fuel combustion process, extending the burning time, work pressure drops, the moment the exhaust valve opening pressure caused by small. 2. Acceleration slow reaction. This is because the lack of intake air, working pressure of the deflagration enough to cause too little power increase.
