| 摘要 |
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</SUB>, and CO, which are inlet into the NOx absorber. Reductants such as H<SUB>2 </SUB>and CO acting along and together help to efficiently regenerate the NOx Adsorber which in turn releases exhausts products such as CO<SUB>2 </SUB>and N<SUB>2</SUB>. 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° C. The plasma fuel converter, NOx adsorber regenerating aftertreatment system of the present invention may be used with any suitable control system.
