Systems and apparatuses include a controller including at least one processor coupled to a memory storing instructions that, when executed by the at least one processor, causes the at least one processor to: receive data indicative of at least one of a current route or of a current performance of a vehicle; correlate at least one of the current route or the current performance to a control strategy; and determine at least one of a timing or a duration of an active regeneration event for an aftertreatment system based on the correlated control strategy.

Systems and methods for management of exhaust aftertreatment systems using predictive analytics

Systems, apparatuses, and methods include predicting a sulfur exposure of one or more copper-zeolite catalysts deployed in an exhaust aftertreatment system; comparing the predicted sulfur exposure to a predefined sulfur exposure threshold; and responsive to the determination, heating the exhaust aftertreatment catalyst to a predefined heat treatment temperature for a predefined time period to desulfate the one or more copper-zeolite catalysts.

Systems and methods for selective catalytic reduction and/or ammonia slip catalyst sulfur protection

A diagnostic system () is provided and includes a sensor () disposed downstream from an exhaust gas aftertreatment system. Also included in the diagnostic system () is a central diagnostic unit () configured to diagnose a condensation condition associated with the sensor () for mitigating a sensor failure due to water condensation on the sensor (), the central diagnostic unit () performing the diagnosis on the condensation condition based on water storage and release information related to a component of the exhaust gas aftertreatment system. The sensor () is activated based on the water storage and release information.

System and method to mitigate sensor failures due to water condensation

A method of recovering selective catalytic reduction catalysts relates to metal-Zeolite based catalysts. A selective catalytic reduction catalyst service event where a metal-Zeolite based selective catalytic reduction catalyst of an exhaust aftertreatment system may perform below a threshold level of performance is determined. The selective catalytic reduction catalyst then exposed to a recovery fluid selected to facilitate movement of metal ions.
