Abstract:
1. An exhaust-gas recirculation device for an internal combustion engine, the exhaust-gas recirculation device comprising: a turbine, wherein a turbine inlet is connected to an exhaust manifold and wherein the turbine is configured to convert kinetic energy contained in an exhaust-gas flow through the exhaust manifold into rotational energy; an exhaust-gas aftertreatment device, wherein an exhaust-gas aftertreatment device inlet is connected to an outlet of the turbine, the exhaust-gas aftertreatment device configured to reduce a pollutant content in the exhaust-gas flow, the exhaust-gas aftertreatment device comprising an electric grid heater arranged between the outlet of the turbine and the exhaust-gas aftertreatment device inlet and configured to heat the exhaust-gas flow; a medium pressure exhaust-gas recirculation loop, wherein the medium pressure exhaust-gas recirculation loop has an inlet connected to an outlet of the electric grid heater, and is arranged upstream of the exhaust-gas aftertreatment device; and a temperature sensor, wherein the temperature sensor is arranged downstream of the electric grid heater and upstream of the exhaust-gas aftertreatment device and measures a temperature of the exhaust-gas flow.
