[0032] As described in the background technology, the engine lubrication system is an important part of the engine. Its main function is to reduce the friction and wear between the moving parts of the engine, and at the same time it plays the role of cooling, cleaning, sealing and rust prevention, which has a vital impact on the reliability and durability of the engine. The engine lubrication system mainly includes an oil pan, an oil pump, an oil filter, an oil radiator, a main oil channel, an oil distribution channel, a pressure limiting valve, an oil pressure sensor, an oil dipstick, etc. When the engine is running, the oil pump draws lubricating oil from the oil pan through the oil suction port, and delivers it to the main oil channel after pressurization, and then After that, the oil flows along the oil distribution channel to various parts that need lubrication, such as the crankshaft, connecting rod, camshaft, etc., forming an oil film on the surface of these parts to reduce friction. At the same time, the oil will also take away the heat generated by friction and play a cooling role. After lubrication and cooling, part of the oil will flow back to the oil pan, and the other part will continue to circulate. The oil filter continuously filters impurities in the oil to maintain the cleanliness of the oil. The pressure limiting valve ensures that the oil pressure is maintained in a suitable range to ensure the normal operation of the lubrication system. The oil pressure sensor monitors the oil pressure in real time and provides information for the vehicle's control system. However, the position of the oil suction port in the current engine lubrication system is fixed. During the driving process of the vehicle, the oil level in the oil pan will move relative to the oil pan as the vehicle tilts. Since the position of the oil suction port in the lubrication system is fixed, it is possible that the oil suction port is at least partially higher than the oil level, resulting in air being sucked into the lubrication system, affecting the lubrication effect of the lubrication system.
