Zusammenfassung:	The utility model discloses a cold end EGR bypass valve. The utility model belongs to the technical field of engines, key points of the technical scheme are as follows, bypass valve body, a waste gaschannel is formed in the bypass valve body; a center rod and a driver assembly are installed on the bypass valve body. Wherein the driver assembly is fixedly installed on one side of the bypass valvebody through a support, the driver assembly is fixedly connected with the center rod through two M6 nuts, two threaded holes are formed in the center rod, valve plates are connected to the two threaded holes in a threaded mode, and the center rod is inserted into a waste gas channel of the bypass valve body after the valve plates are assembled. The cold-end EGR bypass valve is arranged behind an EGR cooler (at the cold end), the bypass valve body is made of a die-casting aluminum material, the weight is light, the working temperature of the EGR bypass valve is not high, internal parts do not need to be made of a high-t
