Abstract: Systems, apparatuses, and methods for monitoring a catalyst health parameter are provided. A system includes one or more processing circuits having one or more memory devices coupled to one or more processors. The one or more memory devices store instructions that, when executed by the one or more processors, cause the one or more processors to: receive a temperature of exhaust gas entering the aftertreatment system; determine a catalyst loading based on the temperature; determine a catalyst health notification threshold based on the catalyst loading and an amount of time relating to the catalyst loading; and output a notification indicative of the health notification threshold being met.

Abstract: Systems and apparatuses include a circuit structured to receive information indicative of a catalyst health, determine a catalyst health management criteria has been met based on the information, determine a catalyst loading based on the information and the catalyst health management criteria being met, and compare the determined catalyst loading to a predetermined loading limit. A notification circuit is coupled to the circuit and structured to provide a notification when the determined catalyst load exceeds the predetermined loading limit.

Abstract: Systems, apparatuses, and methods for monitoring a catalyst health parameter are provided. A system includes one or more processing circuits having one or more memory devices coupled to one or more processors. The one or more memory devices store instructions that, when executed by the one or more processors, cause the one or more processors to: receive information indicative of at least one of a temperature of exhaust gas entering the aftertreatment system, a time at idle, or a mass flow of exhaust gas; determine a catalyst health management criteria based on the information; determine a catalyst health indicator based on the catalyst health management criteria being met; compare the determined catalyst health indicator to a predetermined health threshold criteria; and provide a notification based on the determined catalyst health indicator being less than the predetermined health threshold criteria.

Abstract: Systems and apparatuses include a circuit structured to receive information indicative of a catalyst health, receive information from a sensor array indicative of a catalyst activity, determine a catalyst health management criteria has been met based on the information, determine a catalyst age based on the information indicative of the catalyst activity and the catalyst health management criteria being met, compare the determined catalyst age to a predetermined age threshold, and provide a notification when the determined catalyst age exceeds the predetermined age threshold.
