油压突然增高会烧瓦发动机在使用过程中，要勤观察机油压力表的变化情况，工作油压基本保持一定值是正常情况．突然增高或降低都是因故障造成的。内燃机润滑系机油压力的变化规律是随着各配合运动零部件的磨损，间隙逐渐增大，泄漏量增加，压力逐渐降低的。然而，人们往往... Sudden increase in oil pressure will burn the engine during use, to observe the changes in the oil pressure gauge, the work of hydraulic pressure to maintain a certain value is normal. A sudden increase or decrease is caused by the fault. The change rule of lubricating oil pressure of internal combustion engine is that with the wear of each moving parts, the clearance increases gradually, the leakage increases and the pressure decreases gradually. However, people tend to ...
