Abstract: An exhaust aftertreatment system having a NOX absorber-catalyst and an ammonia-SCR reactor. During regenerations, the NOX absorber-catalyst generates ammonia. The ammonia-SCR reactor captures this ammonia and later uses it to reduce NOX. A Venturi is provided in an exhaust conduit connecting the NOX absorber-catalyst to the ammonia-SCR reactor. The Venturi draws sufficient air to keep the ammonia-SCR reactor under lean conditions throughout the NOX absorber-catalyst regenerations. Maintaining lean conditions for the ammonia-SCR reactor in this manner mitigates poisoning of the ammonia-SCR reactor by hydrocarbons slipping from the NOX absorber-catalyst during the regenerations. Mitigating this poisoning improves the performance of the exhaust aftertreatment system and reduce the loss of useful ammonia to oxidation.

Accordingly, the temperature of the catalyst can be prevented simply and effectively from decreasing excessively, maintaining combustion conditions to provide a properly high thermal efficiency.

Abstract: Method of controlling the active regeneration of a particulate filter through dynamic control of the temperature at the outlet of an oxidation catalyst. A control law is defined for a hydrocarbon flow rate at the oxidation catalyst inlet, by means of the ratio between a temperature demand and a gain. The gain can be corrected so as to take account of the transient phenomena that occur in the oxidation catalyst during a gas flow rate variation. The temperature demand can comprise a precompensation term to compensate for the effects of a temperature variation at the oxidation catalyst inlet. The temperature demand can comprise a feedback term calculated by a controller whose parameters are automatically calculated by means of a physical model of the catalyst, during operating conditions variations. Any combination of these terms allows to define a suitable control law.

The electronic control unit selects the first or third control mode in the operation region where ignition is possible, and selects the second or third control mode in the operation region where ignition is not possible.
