摘要： A dual NOx trap system for reducing NOx emissions from an internal combustion engine. The system is plumbed and controlled such that the NOx adsorption time of a trap is decoupled from the NOx regeneration time. A trap is taken out of service for regeneration only for the minimum required regeneration time and then is placed back into service. Because regeneration times are short relative to adsorption times, during most of the working life of the assembly both of the traps are in service in NOx-trapping mode. Thus, higher NOx-trapping efficiencies are provided over most of the working life of the system because each unit volume of catalyst is in service for more than 50% of the time, permitting a smaller volume of catalyst for each trap than in a prior art system. Further, shorter off-line regeneration times result in reduced cooling of the traps during regeneration.

摘要： A motor vehicle exhaust aftertreatment system includes an exhaust conduit that includes a NOx adsorber, a particulate filter, a reformer for generating reformate containing hydrogen and carbon monoxide from a fuel source, a reformate conduit, and an oxygen sensor. In response to a pressure drop through the particulate filter attaining a threshold value, reformate is introduced under selected controlled flow conditions into the exhaust conduit and caused to undergo combustion. The resulting exotherm maintains the temperature within the particulate filter within a selected range that is effective to cause oxidation and removal of soot from the particulate filter. Introduction of reformate into the exhaust conduit is discontinued when the pressure drop through the particulate filter is decreased to a selected value.

摘要： A scaleable inter-digitized tine non-thermal plasma reactor element includes at least one pair of inter-digitized tine end connectors connected together defining gas passages between the tines. The prepared inter-digitized tine reactor element has a scaleable height, width, and length. Connectors are defined that enable efficient non-thermal reactor element fabrication for widely varying applications having various flow throughput and constituent reduction requirements. An inter-digitized tine reactor element is provided having several zones that are selectively powered so that the effective length of the reactor can be adjusted during operation for optimal efficiency over a range of operating conditions Structural carrier connectors and structural conductor connectors are provided. Structural carrier connectors have tines defined in a side to side basis comprising a high-k dielectric layer, electrode layer, structural dielectric, electrode layer, and high-k dielectric layer. Structural conductor connectors have tines defined in a side to side basis comprising a high-k dielectric layer, structural conductor, and high-k dielectric layer. The scaleable reactors include double, single or null dielectric barrier inter-digitized tine non-thermal plasma reactors. The double dielectric barrier reactor has plasma cells bounded by a dielectric barrier in the plasma direction. The single dielectric barrier reactor has plasma cells bounded by a dielectric barrier on one side and by an electrode on the opposite side, in the plasma direction. The null dielectric barrier reactor has plasma cells bounded by electrodes on each side, in the plasma direction.
