Abstract
The invention provides a NOx adsorber aftertreatment system for internal combustion engines which utilizes a plasma fuel converter operatively coupled to at least one NOx adsorber to aid in the regeneration of the NOx adsorber. Fuel and engine exhaust is injected into a plasma fuel converter upstream of a NOx absorber producing reductant such as H.sub.2, and CO, which are inlet into the NOx absorber. Reductants such as H.sub.2 and CO acting along and together help to efficiently regenerate the NOx Adsorber which in turn releases exhausts products such as CO.sub.2 and N.sub.2. Using the reductants generated by the plasma fuel converter NOx adsorbers, catalytic soot filter, and the like can be regenerated at exhaust temperatures less than 250.degree. C. The plasma fuel converter, NOx adsorber regenerating aftertreatment system of the present invention may be used with any suitable control system.
