Systems And Methods For Monitoring The Health Of A Mid Bed Oxidant Injection System
Abstract: A system includes a controller programmed to determine an oxidation state of a three-way catalyst (TWC) assembly based on a first signal representative of a measured oxygen (O2) storage of the TWC assembly received from a radio frequency (RF) probe disposed within the TWC assembly, to determine whether a temperature of a fluid flowing into an ammonia slip catalyst (ASC) assembly is within a desired temperature operating range based on a second signal representative of the temperature of the fluid adjacent an inlet of the ASC assembly, to determine whether a concentration of nitrogen oxides (NOx) in the fluid exiting an outlet of the ASC assembly is within desired limits based on a third signal representative of the concentration of NOx in the fluid, and to determine whether to perform diagnostics on a component of an exhaust aftertreatment system based at least on the first, second, and third signals.
