Abstract:
A system and method includes an exhaust aftertreatment system for an internal combustion engine having a reductant stored in a solid storage media. The reductant is released by heating the solid storage media to convert the reductant to gaseous form. The system and method determines the quality of the solid storage media by measuring operating parameters of the aftertreatment system and comparing the operating parameters to expected parameters stored in a memory of a controller of the system.
