abnormal causes of autometer oil temp water temp oil pressure gauge

• 2022-10-28

Under normal operation, the autometer water temp and oil temp are between 70 and 80 degrees. Under high load, 95 degrees is allowed for a short time, but not high temperature for a long time. The transmission oil temperature is between 60 and 90 degrees, and cannot exceed 110 degrees under high load. The normal oil pressure of a autometer is about 300kpa. The three gauges are reliability of the auto . The causes of abnormal automobile oil pressure are as follows: 1. The oil in the oil pan is too little, the oil becomes thin, deteriorated, and the viscosity decreases; 2. The oil pump is severely worn or improperly assembled; 3. The oil filter screen or filter is seriously blocked by oil sludge, making it difficult for oil to enter the main oil circuit; 4. The oil inlet pipe joint of the oil pump is not tightly sealed, causing serious air suction; 5. The oil drain plug of the oil pan is loose or the oil pipe is broken or cracked, resulting in a large amount of oil leakage. The oil pressure regulator is installed at one end of the fuel distribution pipe. Its function is: 1. Adjust the fuel pressure of the fuel supply system to make the difference between the system oil pressure and the intake manifold pressure constant at 300 kpa; 2. Pressure pulsation generated during fuel supply of buffer fuel pump and pressure fluctuation caused by intermittent fuel injection of fuel injector.

Water temperature gauge: in general, except for some more advanced vehicles, the temperature gauge can be said to be indicative (such as blue and red). For example, when the temperature is 80 ° C and 90 ° C, only blue can be seen, while the added water temperature gauge can more accurately grasp the temperature of cooling water in the water tank, which is directly expressed in figures. Oil temperature gauge: The sensor of the oil temperature gauge is usually installed near the oil pan or oil filter element, but wherever it is, the indicated oil temperature is lower than the actual oil temperature in the engine, and the oil temperature will rise when the oil volume decreases. If a sensor is installed in the oil pan, the oil temperature indication will be 5 to 10 degrees lower than the actual temperature because the high heat engine is mixed with the lower temperature oil in the oil pan.
