发动机功率不足故障因涉及面广,一下子难以理顺它的关系,即使对一个老机手来说也是一个感到头痛的事,但经过多次实践,不断总结,采取广阔思路,推理分析,集中要害,顺藤摸瓜的办法比较有效。也就是说要“八看八查”。 一、看上、下冒烟查磨损 在发动机工作时,打开加机油的口盖,如有一股股浓烟从口盖冒出,说明缸壁活塞环各间隙磨损过大或超限,在活塞压缩及爆发行程,从各大间隙渗到曲轴箱,并从加机油口中冒出,称下冒烟。若各间隙不符合要求应及时修理。
Insufficient engine power Because of its wide range of implications, it is hard to rationalize its relationship at a stroke. It is a headache even for an experienced aircraft carrier. However, after many times of practice, it has been concluded that a wide range of thinking, reasoning and analysis are necessary Essential, straightforward approach is more effective. That is to say “eight to eight check.” First, fancy, under the smoke check wear and tear in the engine work, open the mouth to add oil, if a Unit of smoke from the flap pops up, indicating cylinder wall piston ring wear excessive or excessive clearance, the piston Compression and explosion stroke, seepage from the major gap to the crankcase, and from the Canadian oil port in the rise, said the next smoke. If the gap does not meet the requirements should be promptly repaired.
