Abstract

A motor vehicle combustion engine includes an air supply section and an exhaust gas recirculation section that includes a particle filter and an SCR exhaust gas purification component. A first exhaust gas turbocharger includes a turbine arranged upstream of the particle filter in the exhaust gas section. A first exhaust gas recirculation line, which diverges from the exhaust gas section upstream of the turbine of the first exhaust gas turbocharger, and a second exhaust gas recirculation line, which diverges from the exhaust gas section downstream of the particle filter are provided to recirculate the exhaust gas from the exhaust gas section into the air supply system. An SCR catalyst is arranged in the second exhaust gas recirculation line.
