An exhaust gas recirculation system for an internal combustion engine, which comprises an intake plenum, an exhaust gas system, and a fresh-air feed line and an exhaust gas recirculation line connected to the intake plenum, includes a sensor, arranged in the intake plenum for measuring an amount of an exhaust gas component, and a controller constructed for outputting a correcting variable based on the sensor and adjusting the percentage by mass of inert gas in the intake plenum on the basis of the correcting variable. The sensor arranged in the intake plenum is a gas concentration sensor which is equipped for determining the air ratio, the oxygen concentration or the carbon dioxide concentration in the intake plenum and to output as sensor variable a variable representing the air ratio, the oxygen concentration or the carbon dioxide concentration to controller.
An exhaust gas recirculation system for an internal combustion engine having an intake plenum and a fresh-air feed line coupled to the intake plenum, the engine further having an exhaust gas system coupled downstream of it, the system comprising:
A method for controlling the mixing ratio of exhaust gas to fresh air in an exhaust gas recirculation system of an internal combustion engine, the engine having an exhaust gas system coupled downstream of it, the engine further having a fresh-air feed line and an exhaust gas recirculation line coupled to an engine intake plenum, the method comprising:
