Patent number: 7900441Abstract: The invention provides a NOx adsorber aftertreatment system for internal combustion engines which utilizes at least one precat operatively coupled to at least one NOx adsorber to aid in the regeneration of the NOx adsorber. Fuel is injected into a precat located upstream of a NOx absorber producing heat, H2O, and reductants such as CO, HC, and volatile hydrocarbons, which are input into the NOx absorber. The combination of heat, water, and reductants help to efficiently regenerate the NOx Adsorber which in turn releases exhausts products such as CO2 and N2. Regeneration of a NOx adsorber can be performed during periods of reduced exhaust gas flow lowering the fuel penalty associated with NOx adsorber regeneration. The pre-cat, NOx adsorber regenerating aftertreatment system of the present invention may be used with any suitable control system.Type: GrantFiled: February 12, 2004Date of Patent: March 8, 2011Assignee: Fleetguard, Inc.Inventors: Rahul Mital, Bradlee J.
