dual gauge electric oil pressure water temp
The oil temperature of the normal operating temperature of the engine when the car is running normally is about 90~110 ℃. The normal operating temperature of the engine is about 90~110 ℃. Before the operating temperature is reached, due to the low temperature of the fuel supply system, it is impossible to effectively gasify the gasoline. In this state, it is not easy to burn and start the engine. Normal oil pressure must be maintained when the engine is operating. If the oil pressure is too low, the friction surfaces will wear faster due to insufficient lubrication; If the oil pressure is too high, it is easy to damage the oil seal and oil pipe and consume engine power. When the vehicle is running.
1. If the oil pressure is too low, the lubrication condition of the engine will be damaged, resulting in poor lubrication, cooling and cleaning, which will cause adhesion and wear of parts. Too large clearance between crankshaft main journal and connecting rod journal and bearing, too low oil viscosity and broken filter element will cause too low oil pressure.
2. Too high oil pressure is rare, but it will also damage the normal lubrication conditions. If the oil viscosity is too high, the oil is deteriorated and gummed, 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.
3. The engine oil consumption is excessive. The ratio of normal engine oil consumption to gasoline is 0.5% - 1%. If it is greater than 1%, it is abnormal. In addition to oil leakage, the reason for excessive oil consumption is more oil burning. The main reasons are: the clearance between piston and cylinder wall is too large; The piston ring is worn or the elasticity is insufficient; The valve guide is excessively worn; The valve stem oil seal is damaged. The sealing performance of piston rings can be greatly improved, worn internal parts can be repaired, and the consumption of engine oil can be reduced by using the ultra strong repair agent of Chinip engine.
The gasoline engine works normally at a constant temperature of 80 degrees, and the cooling fan higher than 80 degrees will rotate. When the air conditioner is turned on, it will decrease because the air conditioner fan is running all the time. The normal operating temperature of the diesel engine is generally 45-75 ℃. The cooling fan is always running when the machine is started. Only 75 ℃ can be reached when the heavy goods are loaded on a slope in hot weather.
