Abnormal display of engine oil pressure indicator
原因分析:当表的指针显示油压不正常时,说明发动机部件有故障。如果油表指针显示压力偏低或是仪表指针显示波动大,可能是由于机油泵磨损大、滤清器被脏物阻塞、吸油滤网置露出油面、机油液面低、油路中混入空气以及压力表有故障等原因造成的。另外,润滑油粘度偏低,油路密封和润滑性差、润滑油过冷粘度太大、润滑油油泥沉积太多等也会引起机油压力指示表显示异常。
Cause analysis: when the pointer of the gauge shows that the oil pressure is abnormal, it indicates that the engine components are faulty. If the pressure indicated by the pointer of the oil gauge is low or the indication of the pointer of the instrument fluctuates greatly, it may be caused by large wear of the oil pump, blockage of the filter by dirt, exposure of the oil suction screen, low oil level, mixed air in the oil circuit and failure of the pressure gauge. In addition, the low viscosity of lubricating oil, poor sealing and lubricity of oil circuit, too high supercooling viscosity of lubricating oil and too much sludge deposition of lubricating oil will also cause abnormal display of oil pressure indicator.
解决:应及时到修理厂进行换修理。
Solution: go to the repair shop for replacement and repair in time.
拧开散热器盖发现总有一些油渍飘浮在水面上,而且发现换机油时有水分。
When unscrewing the radiator cap, it was found that there were always some oil stains floating on the water, and there was water when changing the oil.
原因分析:发动机有两大循环系统,一个是冷却液循环系统,另一个是润滑油循环系统,两大系统互不贯通。如果水中有油或油中有水,说明两个循环系统中的某个隔离地方出现了问题。“油进了水”与“水进了油”是两种不同性质的故障。“油进了水”是发动机机体本身出了毛病,而“水进了油”则多是发动机配件引起的,其故障性质不一样。
Cause analysis: the engine has two major circulation systems, one is the coolant circulation system and the other is the lubricating oil circulation system. The two systems are not connected with each other. If there is oil in the water or water in the oil, there is a problem in an isolated place in the two circulating systems. "Oil into water" and "water into oil" are two different faults. "Oil into water" is the fault of the engine body itself, while "water into oil" is mostly caused by engine parts, and its fault nature is different.
解决:应及时到修理厂进行换修理。
Solution: go to the repair shop for replacement and repair in time.
汽车加速时机油压力指示灯会点亮
The oil pressure indicator will light up when the car accelerates
原因分析:机油灯点亮有实与虚两种情况。所谓实,就是机油压力确实低,低到指示灯发出警告的程度,说明润滑系统确有故障,必须予以排除。所谓虚,正像怀疑的那样,机油润滑系统没有故障,而是机油压力指示灯系统发生了故障,错误地点亮了指示灯。
Cause analysis: there are real and virtual situations when the machine oil lamp is on. The so-called reality means that the oil pressure is really low, so low that the indicator light sends a warning, indicating that there is a fault in the lubrication system and must be eliminated. The so-called virtual, just as suspected, the oil lubrication system is not faulty, but the oil pressure indicator system is faulty and the indicator is wrongly lit.
解决:这种故障虽不会影响发动机的正常工作,但也应及时找到根源,排除为妙。通常情况下实症的可能性较大,应作为判断故障的主要思路。
Solution: Although this fault will not affect the normal operation of the engine, the root cause should be found and eliminated in time. Under normal circumstances, the possibility of actual symptoms is large, which should be used as the main idea to judge the fault.
