Abstract
A method and device for regenerating an exhaust gas aftertreatment component for filtering soot particles in an engine having a first cylinder group, exhaust gases being guided through an exhaust gas channel and whose fuel/air mixture ratio is set via a fuel metering system, activated via a control unit, by a control loop for setting a lambda value using a signal of a first exhaust gas sensor, in the exhaust gas flow direction upstream from a catalytic converter, having at least another cylinder group, exhaust gases being guided through another exhaust gas channel and whose fuel/air mixture ratio is set via another fuel metering system by another control loop for setting another lambda value based on the signal of another exhaust gas sensor, in the exhaust gas flow direction upstream from a catalytic converter, the separate channels joined together downstream to form a shared channel, having a shared catalytic converter.
