Method for exhaust-gas aftertreatment with reduced emissions
Abstract:
An exhaust-gas recirculation device for an internal combustion engine, a method for controlling an exhaust-gas recirculation device, a drive for a motor vehicle having an exhaust-gas recirculation device, and a motor vehicle having a drive of said type are described. The exhaust-gas recirculation device comprises a turbine, and an exhaust-gas aftertreatment device. The exhaust-gas aftertreatment device has an inlet connected to an outlet of the turbine, and is configured to reduce a pollutant content in the exhaust-gas flow. An electric grid heater is arranged between the outlet of the turbine and the inlet of the exhaust-gas aftertreatment device and is configured to heat the exhaust-gas flow.
