[0036] The specific operating principle is:

[0037] When using this device, you first need to pull the adjusting member outward to drive the adjustable rear shell so that the adjustable rear shell moves outward along with the sliding of the second slider in the second slide groove until it moves to the end of the second slide groove away from the fixed rear shell and stops moving. At this time, rotate the adjusting member so that the first rotating member and the adjustable rear shell rotate synchronously by 90° and then stop rotating. At this time, push the adjusting member inward to drive the adjustable rear shell so that the adjustable rear shell moves inward along with the sliding of the second slider in the second slide groove until it moves to the end of the second slide groove close to the fixed rear shell and stops moving. At this time, the second slider is fixed to the fixed groove (not shown in the figure), and the middle of the rear side of the adjustable rear shell and the fixed rear shell are left and right.

The various parameter information monitored by the sensors, position sensors and liquid level sensors are transmitted to the ECU in the form of electrical signals. The ECU imports the processed data into the digital twin model in the digital twin model carrier in the form of electrical signals. The digital twin model runs simulations based on various data, studies the performance of the engine and generates feasible improvement plans. The digital twin model then transmits the data of the improvement plan to the ECU in the form of electrical signals, allowing the ECU to adjust the operation of various components in the engine in a timely manner. When it is necessary to study and analyze the simulation plan formed by the digital twin model through the digital twin model carrier, only The controller controls the two electric push rods to extend and drive the digital twin model carrier, so that the digital twin model carrier gradually moves upward as the first slider slides in the first slide groove under the push of the electric push rod. At the same time, as the digital twin model carrier moves upward, the impact force on the baffle causes the baffle to gradually change from a horizontal state to a vertical state as the second rotating part rotates. When the first slider slides to the top of the first slide groove, it stops sliding. At this time, the digital twin model carrier is completely outside the main shell (the collection process of the digital twin model carrier is the opposite, which will not be elaborated here). At this time, the user can study and analyze the simulation scheme formed by the digital twin model.
