An exhaust gas recirculation system is provided for an internal combustion engine having reciprocating piston design with an exhaust gas turbocharger unit having an exhaust gas turbine and a supercharger. The internal combustion engine has a machine housing accommodating one or more cylinders having reciprocating pistons, which is provided with a suction unit and an exhaust gas outlet unit, which is connected to the exhaust gas turbine by way of an exhaust gas line. The exhaust gas line supplies at least a part of the exhaust gas stream to the suction unit via the exhaust gas recirculation system. To optimize the exhaust gas recirculation system, it has a pipe branch, which is connected to the exhaust gas line and is connected to an exhaust gas recirculation line with a control element interconnected. The exhaust gas recirculation line extends, on the one hand, with a first supply line section outside and, on the other hand, with a second supply line section in an interior of, a suction unit container of the suction unit. An exhaust gas stream is conveyed by the second supply line section into the suction unit container for targeted mixing of exhaust gases with the air volume contained in the suction unit container.
