what should the oil pressure gauge read
The oil pressure gauge is easy to read. It has a digital BA heat on it. This is a reading gauge with only a pressure gauge. 1mpa=10bar. The oil pressure gauge of the car is a kind of detection work for the normal operation of the engine; the general oil pressure gauge will have the words Mpa or kPa, and the oil pressure of some imported cars.
Table OLL: Under normal circumstances, it is normal for the engine oil pressure to be kept within the pressure range of 150~350kPa. If it is lower or higher than this range, it will cause the engine to fail to start or stall. First of all, look at the zeroing of the oil pressure gauge, that is, when the engine is in a static state without oil pressure, the oil pressure gauge should be zeroed! Because the oil pump is a mechanical pump, the oil pressure increases as the engine revs when the engine is running. Therefore, the higher the engine running speed, the higher the oil pressure supplied by the oil pump. The level of engine oil pressure, the turbine flowmeter indicates the quality of the technical state of the lubrication system; conversely, whether the technical state of the lubrication system is normal can also be reflected from the oil pressure gauge. Once the oil pressure gauge indicates abnormality, stop immediately to check and eliminate it. 1. The oil pressure has always been very low. No matter the engine is at low speed or high speed, low temperature or high temperature of db2r_8, the oil pressure gauge always indicates below 0.1Mpa, and the oil pressure warning light is flashing, which means that the oil pressure is too low.
The reasons should be checked from the following aspects:
First unscrew the oil dipstick to see if there is enough oil in the oil pan and whether the oil is too thin; secondly, check whether the oil pressure gauge and the induction plug are out of order, remove the wire of the induction plug and directly ground it. If the oil channel is sprayed out, the pressure is very high, and the fingers can't hold it, it means that the induction plug is damaged; then replace the test with a good oil pressure gauge, if the oil pressure is normal, it means that the crude oil pressure gauge is damaged; check the process oil plug on the body again There is no looseness, whether the oil pipe is broken, and whether the pressure valve is stuck.
2. The oil pressure suddenly drops to zero When the engine is working, the oil pressure gauge indication suddenly drops to zero from the normal value, and the oil pressure warning light flashes. At this time, you should first check whether there is oil in the oil pan. If there is no oil, it means that the oil pipe is broken, cracked or the oil drain plug of the oil pan is loose, resulting in oil leakage. Next, check whether the oil pressure gauge and the induction plug are damaged. Then check the oil pump drive shaft, whether the drive pin is broken and the oil pump stops working.
Finally, check whether the oil filter is blocked by foreign objects, whether the connecting rod bearing purification oil cavity screw plug is loose, etc., and remove it in time.
