Summary: | A device is provided for exhaust gas recirculation (EGR), in particular in diesel engines, from the exhaust gas tract into the fresh air path of the engine, wherein a cooling device connected to the cooling system of the engine is provided within an EGR section as an exhaust-gas (EG)/coolant heat exchanger, with which an EGR valve for proportioning the EG recirculation rate is associated. The EGR valve is connected to a coolant, and the cooling device comprises an EG pre-cooler and an EG main cooler connected downstream of the EG pre-cooler. The EGR valve is installed between the EG pre-cooler and the EG main cooler in a valve housing between the EG pre-cooler and the EG main cooler. A method for EGR is provided as well. |
