Abstract:
An exhaust gas recirculation system for a gasoline engine, including an exhaust gas line, which can be connected to an exhaust manifold of the gasoline engine and which includes a turbine, and an inlet line, which can be connected to an intake manifold of the gasoline engine and which includes a compressor. A main exhaust gas catalytic converter is provided in the exhaust gas line, and at least one exhaust gas recirculation line_I is provided which branches off from the exhaust gas line upstream of the turbine and opens into the inlet line downstream of the compressor. At least one particle filter_I is provided which is placed in the exhaust gas recirculation line_I or in the exhaust gas line upstream of the exhaust gas recirculation line_I. The particle filter_I has a 3/Ox coating, and at least one cooler_I is provided within the exhaust gas recirculation line_I downstream of the at least one particle filter.
