Abstract
Systems and methods for controlling and managing ammonia slip are provided. A method includes: receiving, by a controller, data regarding operation of an exhaust aftertreatment system; determining, by the controller, that a condition for ammonia slip is present based on the data regarding operation of the exhaust aftertreatment system; determining, by the controller, that a condition for ammonia storage is present based on the data regarding operation of the exhaust aftertreatment system; and, commanding, by the controller, a heater to activate and warm a component of the exhaust aftertreatment system to reduce the stored amount of ammonia.
