在汽车发动机工作时,汽缸内燃料—空气混合气燃烧瞬时温度可高达2000℃,为使发动机在最佳工作状态(冷却水温度在80～90℃),特别是组成燃烧室的活塞、汽缸套、汽缸盖以及汽缸垫不被高温烧蚀,燃烧室周围都有循环冷却水及时将热量带走,经散热水箱散发到大气中。但因维修、使用不当,导致冷却水进入汽缸,发动机工作异常的故障时有发生。下面是几种汽缸进水的现象和预防方法,可供维修诊断参考。
In the car engine work, the cylinder fuel-air mixture combustion instantaneous temperature up to 2000 ℃, in order to make the engine in the best working condition (cooling water temperature at 80 ~ 90 ℃), especially the composition of the combustion chamber piston, cylinder liner , The cylinder head and the cylinder pad are not ablated by the high temperature, and the circulating cooling water around the combustion chamber takes away the heat in time and is distributed to the atmosphere through the hot water tank. However, due to maintenance, improper use, leading to cooling water into the cylinder, the engine malfunction occurred from time to time. The following is the phenomenon of several cylinder water and prevention methods for maintenance diagnosis reference.
