normal oil pressure gauge reading
It is generally maintained at 0.2-0.5mpa. When the engine is idling, the oil pressure shall not be less than 0.1MPa. If the oil pressure is too low, the lubrication condition of the engine will be damaged, resulting in poor lubrication, cooling and cleaning, and adhesion and wear of parts. Excessive clearance between crankshaft main journal and connecting rod journal and bearing, low oil viscosity and broken filter element will cause low oil pressure.
High oil pressure, although rare, will also destroy normal lubrication conditions. If the oil viscosity is too high, the oil is deteriorated and gelled, the filter element and oil passage are blocked, and the pressure regulating valve is improperly adjusted or cannot be opened, the oil pressure will be too high. Excessive oil consumption. The ratio of normal engine oil consumption to gasoline is 0.5% - 1%. If it is greater than 1%, it is abnormal. The reason for excessive oil consumption is not only oil leakage, but also oil burning. Oil pressure gauge, commonly known as oil gauge, indicates the lubricating oil pressure of the main oil passage of the lubricating system when the engine is running.As for the amount of oil in the oil pan, it needs to be measured by the oil dipstick next to the engine. Nowadays, most cars use warning lights instead of oil pressure gauges.
How to check oil pressure gauge:
First of all, the oil pressure gauge should be reset to zero, that is, when the engine is at rest and there is no oil pressure, the oil pressure gauge should be reset to zero fatal frame! Because the oil pump is a mechanical pump, the oil pressure will increase with the increase of engine speed when the engine is running. Therefore, the higher the running speed of the engine, the higher the oil pressure supplied by the oil pump. The turbine flow meter indicates the technical state of the lubrication system according to the engine oil pressure; Conversely, whether the technical state of the lubrication system is normal can also be reflected from the oil pressure gauge. Once the indication of the oil pressure gauge is abnormal, stop the machine immediately for inspection and troubleshooting.
The oil pressure is always very low. No matter the engine is at low speed or high speed, db2r8 low temperature or high temperature, the oil pressure gauge always indicates below 01mpa, accompanied by the flashing of the oil pressure alarm light, which is the low oil pressure. The reasons should be checked from the following aspects:
First, unscrew the oil dipstick to see whether the oil in the oil pan is enough and whether the oil is too thin. Second, check whether the oil pressure gauge and the sensing plug are out of order. Remove the sensing plug wire and ground it directly.
