Exhaust species tracking and notification system

An exhaust aftertreatment system, comprising:

• a catalyst;
• a sensor configured to receive information regarding an exhaust gas temperature entering the exhaust aftertreatment system;
• and
• one or more processing circuits comprising one or more memory devices coupled to one or more processors, the one or more memory devices storing instructions that, when executed by the one or more processors, cause the one or more processors to:
• receive information from the sensor;
• 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.

A method, comprising:

• receiving information indicative of at least one of an engine out temperature, a time at idle, or a mass flow of exhaust gas;
• determining a catalyst health management criteria based on the information;
• determining a catalyst health indicator based on the catalyst health management criteria being met;
• comparing the determined catalyst health indicator to a predetermined health threshold criteria;
• and
• providing a notification based on the determined catalyst health indicator being less than the predetermined health threshold criteria.
