Exhaust management system control

An exhaust management control method comprising the steps of: immediately following a cold start of an engine (14), adsorbing hydrocarbons from engine exhaust into a hydrocarbon adsorber (30); determining when a catalytic converter (32) catalyst light-off is obtained and thereafter purging the adsor...

Beschreibung
Zusammenfassung:	An exhaust management control method comprising the steps of: immediately following a cold start of an engine (14), adsorbing hydrocarbons from engine exhaust into a hydrocarbon adsorber (30); determining when a catalytic converter (32) catalyst light-off is obtained and thereafter purging the adsorber (30), wherein a first regeneration of the adsorber (30) is obtained; detecting an engine off condition of the vehicle; and injecting air through the adsorber (30) following the detected engine off condition while the adsorber (30) is hot enough that coke deposits thereon are oxidized and thereby removed from the adsorber (30), wherein a second regeneration of the adsorber (30) is achieved.
