gauge for temp oil pressure and fuel

1. There is a great and negative correlation between oil pressure and temperature.

2.When the temperature is low, the oil pressure can rise, indicating that there is no problem with the oil pump. If oil with low viscosity is used, the oil pressure will be low. The oil temperature of 105 ℃ is not high. The diesel engine can exceed 120 ℃, so there is a special oil radiator. Because the load of gasoline engine is small, it is not necessary to set up a special radiator. The oil pump hardly goes wrong,Whether the engine can operate normally depends largely on the engine cooling water temperature, oil pressure and oil temperature. The water temperature, oil temperature and oil pressure are in the normal range, which is of great significance for giving full play to the efficiency of the engine, prolonging the service life of the engine and reducing the consumption. The role of oil is more important. Whether the oil pressure and oil temperature are normal is directly related to whether the engine can work normally.

Oil Temperature and Oil pressure

Viscosity is an important index of engine oil. Only the oil with proper viscosity can form an oil film between the friction surfaces to ensure good lubrication of the parts; And take away the metal chips generated by friction to cool some parts that cannot be cooled by water or air flow (such as piston and bearing). The cooling capacity of lubricating oil does not simply depend on its thermal conductivity and other properties. It mainly depends on the oil flow through the friction surface. If the viscosity is too small, the oil is easy to be lost from the fitting clearance. Therefore, it is extremely important to maintain the proper viscosity of the oil. The viscosity is mainly affected by temperature. Therefore, maintaining normal oil temperature is an important condition to maintain oil viscosity.

The oil pressure must be sufficient to overcome the resistance of each pipeline in order to reliably supply the oil to all places required. The influence of oil pressure on the lubrication condition of parts is too high or too low, which will cause poor lubrication and cooling of mating parts, especially the main bearing, connecting rod bearing, bearings and copper sleeve, resulting in severe wear, even burning and more serious accidents.
