工程机械用柴油机的工作环境恶劣，工况变化繁杂，抱缸是最常见的一种故障。造成的主要原因是：润滑被破坏、运动件配合不当和冷却不良等。针对发动机水箱水温偏高问题，曾采取提高风扇转速、增加风量、增大散热面积等措施，但抱缸问题始终未得到解决。几次抱缸事故现场看到的 Engineering machinery diesel engine harsh working conditions, changes in conditions complicated, hold cylinder is the most common kind of fault. Caused by the main reasons are: lubrication is damaged, with improper movement and poor cooling and so on. In view of the high water temperature in the water tank of the engine, measures such as increasing the fan speed, increasing the air volume and increasing the cooling area have been taken, but the problem of holding the cylinder has not been solved yet. Hold the cylinder several times to see the accident scene
