The invention discloses a controllable EGR system with double-inlet integrated cold and hot EGR valves. The system comprises a double-inlet integrated EGR valve body and an exhaust pipe. The double-inlet integrated EGR valve comprises a first inlet, a second inlet, a hot EGR outlet and a cold EGR outlet which are communicated with one another. The exhaust pipe comprises a first exhaust manifold and a second exhaust manifold; the first exhaust manifold is connected with the first inlet and the air inlet end of the turbine. The second exhaust manifold is connected with the second inlet and the air inlet end of the turbine, the cold EGR outlet is connected with the air inlet end of the cooler, the air outlet end of the cooler, the hot EGR outlet and the air outlet end of the air compressor are all connected with the air inlet end of the mixer, and the air outlet end of the mixer is connected with the engine through the air inlet pipe. By means of the design, the adjusting range of EGR temperature and EGR rate is wider, the adjusting and controlling capacity is high, and the structure simplicity is high.
