[0034] The specific usage and function of this embodiment are as follows:

[0035] In this invention, an appropriate amount of engine oil is slowly poured into the test chamber 1 until the liquid level reaches a suitable height. Care is taken to avoid splashing the test oil during the addition process to prevent contamination or damage to the device. The electric cylinder 402 and adjusting plate 403 drive the drive shaft 404 up and down, thereby adjusting the vertical position of the test plate 407. This allows for precise adjustment of the immersion depth of the test plate 407 in the test oil according to different testing requirements. Then, the cylinder 104, drive block 105, and guide assembly 2 drive the chamber cover 106 downwards, sealing the test chamber 1 through the sealing ring 107 and sealing groove 101. This allows the test plate 407 to be immersed to a specified depth in the test oil. The test plate 407 is heated to a specified temperature by the internal heating wire. Based on the actual operating temperature range of the engine crankcase, the heating temperature of the test oil in the test chamber 1 is set using the heating resistance wire 103 and the existing temperature control system. The heating resistance wire 103 is then activated to begin heating the heat-conducting plate 102 and the test oil. During the heating process, the temperature of the experimental oil is monitored in real time to ensure that the temperature remains stable at the set value. The drive motor 305 is started to drive the small bevel gear 306 to rotate, which in turn drives the large bevel gear 303 and the drive cylinder 301 to rotate. By adjusting the speed of the drive motor 305, the stirring speed of the drive shaft 404 and the experimental plate 407 is controlled to simulate the mechanical stirring effect under different working conditions in the engine crankcase. According to actual needs, the stirring speed can be adjusted within a certain range to obtain more comprehensive test data. After a certain time, the cylinder 104 is started to retract its telescopic end, which drives the drive block 105 and the cover 106 to move upward and open the test box 1. The degree of corrosion of the experimental plate 407 is observed and the thickness of the oil film on the experimental plate 407 is measured. The experimental plate 407, through the design of partial immersion in the experimental oil and high-speed rotation, accurately simulates the splashing, gas-liquid coexistence and high-temperature oxidation process of oil in the engine crankcase. This mechanism makes the test results of varnish, carbon deposits and corrosion closer to the actual working conditions, providing key data support for the research and development and quality control of internal combustion engine oils.
