ABSTRACT:
A method of monitoring operation of a dosing system for treating exhaust of an engine includes monitoring a downstream temperature of an exhaust downstream of the dosing system and injecting a dosing agent. A control module determines a temperature differential threshold based on an amount of dosing agent injected and calculates a temperature differential. The control module further evaluates operation of the dosing system based on the temperature differential and the temperature differential threshold.
