Abstract:
An exhaust emission control system can include a reformer a fuel source disposed upstream of and in fluid communication with the reformer, and a NOx adsorber disposed downstream of and in fluid communication with the reformer. The NOx adsorber can include a NOx adsorber catalyst having an acid adsorber disposed on the substrate and a base adsorber disposed over the acid adsorber.
