Abstract
The present invention relates to a method and a corresponding system for catalytic aftertreatment of the exhaust gas of an internal-combustion engine. Two spatially separate catalyst devices are provided in the exhaust gas system. The first of these catalyst devices is arranged in a position close to the engine, and the second catalyst device is arranged in a position away from the engine. An exothermal reaction is caused to take place during warm-up for heating the second catalyst device.
