1柴油机压缩力不足的分析与检查压缩力是指柴油机工作时汽缸产生的压力,汽缸压力不足的原因主要有以下3个方面。(1)压缩系统漏气由于磨损损坏、松动和错位,使构成压缩系统的零件间出现不应有的间隙,不起密封作用,导致汽缸内的空气在压缩过程中泄漏。(1)汽缸垫边缘漏气,致使压缩和做功的行程时有气体窜出。产生汽缸垫漏气的原因有:汽缸盖固定螺栓预紧力不足,或没有按要求的旋紧顺序分次均匀的旋紧;
Analysis and inspection of a lack of compressive force of a diesel engine Compressive force refers to the pressure that the cylinder produces when the diesel engine is working, the reason that the cylinder pressure is insufficient mainly has the following 3 respects. (1) compressed system leakage due to wear and tear damage, loosening and dislocation, the compression system components to make an unwanted gap between, can not afford to seal, resulting in the air cylinder leak during compression. (1) Leakage on the edge of the cylinder liner, resulting in gas escapes during compression and work. Leakage caused by the cylinder liner are due to: the cylinder head bolts less than the pre-tightening force, or not in accordance with the requirements of the tightening sequence evenly tightened;
