When an experiment is started, oil is filled in the floater liquid level regulator, the floater body floats upwards around the fixed rotating shaft in a swinging mode, the thimble surface is made to contact with a contact plane of the needle, the needle is jacked upwards, the needle is in a closed state, after oil is consumed in a standby mode, the oil in the second cavity descends, the floater body swings downwards around the fixed rotating shaft, the needle descends, the outlet of the needle valve is opened, the oil in the first cavity enters the second cavity through the needle valve assembly, then the oil enters the engine to be tested through the second cavity, the oil outlet channel and the real-time consumption pipeline, and consumed oil is replenished in real time.
