摘要： An exhaust-gas recirculation device for an internal combustion engine, in particular for a diesel engine of a passenger car, includes an air-supply line connected to an air inlet of the internal combustion engine and includes an exhaust-gas line connected to an exhaust-gas outlet of the internal combustion engine. A turbine, which drives a compressor disposed in the air-supply line, is disposed in the exhaust-gas line. The exhaust-gas line is connected to the air-supply line via an exhaust-gas recirculation line branching off in flow direction behind the turbine. An adjustable throttle is disposed in the air-supply line in flow direction in front of the compressor in order to achieve higher exhaust-gas recirculation rates. A method for operating an exhaust-gas recirculation device for an internal combustion engine is also provided.

摘要： An internal combustion engine has a high-pressure exhaust-gas recirculation line and a low-pressure exhaust-gas recirculation line with a low-pressure exhaust-gas recirculation valve. The low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system downstream of a turbine of an exhaust-gas turbocharger and opens into a fresh-air system upstream of a compressor of the exhaust-gas turbocharger. An exhaust-gas flap is disposed in the exhaust-gas system downstream from where the low-pressure exhaust-gas recirculation line branches off from the exhaust-gas system. At least one pressure sensor is disposed in the low-pressure exhaust-gas recirculation line and configured such that the at least one pressure sensor determines a pressure difference in the low-pressure exhaust-gas recirculation line between a point upstream of the low-pressure exhaust-gas recirculation valve and a point downstream of the low-pressure exhaust-gas recirculation valve. A method for operating an internal combustion engine is also provided.
