摘要： The present invention provides for an NOx adsorber aftertreatment system for internal combustion engines which utilizes a parallel arrangement of an adsorber catalyst and a bypass. The exhaust flow from the engine is routed through the adsorber during lean operation. At a predetermined regeneration time (for example, when the adsorber catalyst is 20% full), the exhaust gas flow is reduced through the parallel leg that contains the adsorber catalyst to be regenerated (e.g., 20% through the catalyst leg, 80% of the flow to the bypass leg). A quantity of hydrocarbon is injected into the reduced-flow catalyst leg in order to make the mixture rich. Since the flow has been reduced in this leg, only a small fraction of the amount of hydrocarbon that would have been required to make the mixture rich during full flow is required. This will result in a substantial reduction in the fuel penalty incurred for regeneration of the adsorber catalyst. Once the leg has been regenerated, the exhaust flow is switched to flow 100% through the adsorber leg.
摘要翻译：本发明提供一种利用吸附剂催化剂和旁路的并联排列的内燃机的NOx吸附器后处理系统。在稀薄运行期间，来自发动机的排气流通过吸附器。在预定的再生时间（例如，当吸附剂催化剂为20％满时），排气流通过含有待再生的吸附剂催化剂的平行管路（例如，通过催化剂塔的20％，80％流向旁路支路）。为了使混合物富集，将一定量的烃注入减流催化剂载体中。由于在这条腿上已经减少了流量，所以只需要在全流量期间使混合物富集所需的碳氢化合物的一小部分。这将导致吸附剂催化剂再生所引起的燃料损失的显着降低。一旦腿已经被再生，排气流被切换成100％通过吸附器腿。

摘要： 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.

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 H2, and CO, which are inlet into the NOx absorber. Reductants such as H2 and CO acting along and together help to efficiently regenerate the NOx Adsorber which in turn releases exhausts products such as CO2 and N2. 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.

摘要： An apparatus, system, and method are disclosed for regenerating an exhaust gas treatment device. A controller module directs an injector to provide reductant to an exhaust gas treatment device over a plurality of rich intervals during a regeneration cycle. In addition, the controller module directs the injector to reduce the reductant provided to the exhaust gas treatment device over a lean interval between the rich intervals to create a lean environment within the exhaust gas treatment device. In one embodiment, the controller module modifies the reductant provided during each rich interval, the number of rich intervals, the length of the rich intervals, and the length of the lean intervals in response to an exhaust gas state.
