Abstract
The invention provides methods for regenerating pollutant storage and catalytic components of an internal combustion engine's exhaust gas aftertreatment system. These methods include introducing reductant in to catalytic components requiring regeneration in series of discreet portions during a Scheduled Regeneration Event. Typically the flow of exhaust gas to the catalytic component undergoing regeneration is at least partially reduced.
