The invention relates to a centrifugal gas recirculation system, which belongs to the technical field of mechanical design. The centrifugal gas recirculation system comprises a regulating body, a rotary shaft, a rotary body, a stretching body, a centrifugal body, a ball, a pull rod and springs, wherein the rotary shaft is fixedly connected with the rotary body, both the stretching body and the centrifugal body are distributed in the rotary body, the ball is inlaid in the stretching body, one side wall of the centrifugal body makes contact with the stretching body by virtue of the ball, the other side wall of the centrifugal body is connected to the inner wall surface of the rotary body by virtue of a first spring, and the top of the stretching body is connected to the inner wall surface of the rotary body by virtue of a second spring. According to the centrifugal gas recirculation system, when the engine speed is high, a rotary plate rotates clockwise, and the high-pressure exhaust gas recirculation rate of an engine is high; when the engine speed is low, the rotary plate rotates anticlockwise, and the high-pressure exhaust gas recirculation rate of the engine is low. The centrifugal gas recirculation system has the advantages of reasonable design and simple structure and is suitable for optimal design of the high-pressure exhaust gas recirculation system of the engine.
