GAS BACKGROUND INSTALLATION AND PROCEDURES FOR OPERATING A GAS BACKGROUND INSTALLATION

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.
