Beschreibung
Zusammenfassung:	The invention discloses an EGR cooling system, an EGR system and a control method for the EGR cooling system. The EGR cooling system comprises a cooling pipeline, an air cylinder water jacket, a flowcontrol valve and a cooling source module which are arranged at an EGR cooler; the cooling source module, the cooling pipeline and the air cylinder water jacket are connected in sequence; the coolingpipeline comprises a liquid inlet and a liquid outlet; the flow control valve is arranged between the liquid inlet of the cooling pipeline and the cooling source module; and the flow control valve isused for being opened at different opening degrees so as to control the flow rate of cooling liquid entering the air cylinder water jacket from the cooling source module. According to the EGR coolingsystem, the flow control valve for controlling the flow rate of the cooling liquid is arranged at the liquid inlet of the cooling pipeline of the EGR cooler, so that the flow rate of the EGR cooling liquid is adjusted so as to a
