Abstract
A device for cooled recirculation of exhaust gas of an internal combustion engine charged with the aid of an exhaust gas turbocharger, the internal combustion engine having a fresh gas system and an exhaust gas system, which are connected to a two-stage exhaust gas cooler via an exhaust gas recirculation line. A device by way of which a sufficient amount of exhaust gas may be recirculated by simple means is provided. This is achieved in that exhaust gas recirculation line 8a, 8b is connected to an exhaust gas collecting line 7a, 7b of the exhaust gas system upstream from turbine 6 of exhaust gas turbocharger 5 in the direction of flow, an exhaust gas recirculation valve 9a, 9b being connected upstream from first stage 10a, 10b of the exhaust gas cooler in exhaust gas recirculation line 8a, 8b, and a nonreturn valve 11a, 11b is inserted into a continuation line 12a, 12b leading to the second stage of the exhaust gas cooler.
