REGULATING STRATEGY FOR A CATALYTIC CONVERTER CONCEPT FOR EXHAUST-GAS AFTERTREATMENT HAVING A PLURALITY OF NITROGEN OXIDE STORAGE CATALYTIC CONVERTERS |
摘要 |
The present invention relates to a regulating strategy for a special catalytic converter for exhaust-gas aftertreatment. The catalytic converter concept is distinguished in that at least two nitrogen oxide storage catalytic converters are used in the exhaust section of a vehicle. The first, possibly close-coupled unit is followed by one or more nitrogen oxide storage catalytic converters, which are possibly situated in the underbody of the vehicle. The nitrogen oxide storage catalytic converters are then regenerated as a function of the exceedance of nitrogen oxide threshold vales downstream thereof. |
