The lubricating oil is used as a working medium of an engine lubricating system, and the temperature of the lubricating oil directly influences the working state of the engine and the service life of parts. Too high temperature of the lubricating oil can accelerate the aging of the engine oil, reduce the viscosity of the lubricating oil, influence the pressure and the lubricating effect of the engine oil, accelerate the surface abrasion of each part of the engine, and seriously cause the problems of rough engine operation, pull shoe, abnormal sound, bearing locking, engine damage and the like; too low a temperature of the lubricating oil will result in a higher viscosity of the engine oil, higher pressure of the engine oil, higher friction resistance, loss of mechanical power and increased fuel consumption of the engine; in particular, modern engines are equipped with variable oil pumps, which have more severe requirements on the oil temperature.
Therefore, when the engine bench test is performed, the temperature of engine lubricating oil needs to be studied to ensure safe and stable operation of the engine so as to obtain accurate test data, obtain the most reasonable lubricating oil temperature when the engine works, and provide verification and improvement schemes for the design and development of the engine and the lubricating cooling device.
