摘要： The invention relates to a power generation system with a continuously operating fuel reformer. Preferably, the fuel reformer is either off, warming up, or operating with an essentially constant fueling rate. Some of the reformed fuel is intermittently used to regenerate a NOx trap that treats the exhaust of an internal combustion engine. Any reformed fuel not used for other purposes is supplied to a fuel cell. The fuel reformer does not shut down between NOx trap regeneration cycles except when the engine is also shut down. The invention substantially eliminates issues of reformer response time as they relate to NOx trap regeneration.

摘要： One aspect of the invention relates to a particulate filter useful in treating exhaust from a diesel-power vehicle. The particulate filter comprises filter elements for removing particulate matter and an ammonia SCR catalyst. Ammonia can be produced during regeneration of an NOx adsorbant. The adsorbant can be contained in a separate device upstream of the particulate filter or be incorporated within the particulate filter. Another aspect of the invention relates to a method of cleaning exhaust comprising passing the exhaust over an NOx adsorber to adsorb a portion of NOx from the exhaust; passing the exhaust through a particulate filter to remove particulate matter from the exhaust; and removing a further portion of NOx from the exhaust by reducing it with ammonia over an ammonia SCR catalyst. Preferably, a catalyst contained within the adsorbant provides NO2 for continuously regenerating the particulate filter.

摘要： One concept of the inventors relates to a system and method in which a particulate filter comprises at least about 40% by weight of an NOx adsorbant. The filter can be used as both an NOx trap and a particulate filter. By constructing the filter elements using a substantial amount of NOx adsorbant, a large volume of NOx adsorbant can be incorporated into the particulate filter, which substantially reduces the volume and expense of an exhaust system that includes both a catalytic diesel particulate filter and an NOx trap having a large quantity of NOx adsorbant. In a preferred embodiment, the filter also oxidizes NO to NO2. In another preferred embodiment, an SCR catalyst is position downstream of the filter elements.

摘要： One aspect of the invention relates to an exhaust treatment apparatus having an NOx reduction system comprising first and second catalyst beds in series with associated first and second ammonia injectors. The first catalyst bed with its associated ammonia injector preferably targets removing only about 80 to about 95% percent of the NOx in the vehicle exhaust. The second catalyst bed with its associated injector preferably target removing about 70 to about 100% of the remaining NOx. Staging the reduction system in this manner improves control over NOx reduction and reduces the risk of ammonia slip. Other aspects of the invention relate to methods of treating vehicle exhaust to remove NOx and an SCR reactor comprising a housing having an entrance port, an exit port, and an ammonia injection port, wherein the injection port is configured to inject ammonia in between SCR catalyst beds contained in the housing.

摘要： A method is provided for regenerating a LNT in a diesel engine exhaust aftertreatment system. Typically, the aftertreatment system comprises a fuel reformer, a LNT, and a SCR catalyst in that order. Over the course of the regeneration, the concentration or flow rate of syn gas is increased, peaked, and then reduced. Preferably, the syn gas concentration or flow rate and the fuel reformer temperature are simultaneously controlled using at least a fuel injector and an engine intake air throttle. The pattern of increasing the syn gas concentration or flow rate during a first part of the regeneration and decreasing the syn gas concentration of flow rate in a latter part of the regeneration reduces the fuel penalty for the regeneration and improves the ammonia production rate as compared to a system in which the syn gas concentration or flow rate is essentially constant throughout the regeneration.

摘要： A solenoid drive circuit includes a boost energy storage device, such as a capacitor, that captures energy from and discharges energy to a solenoid. Switches control the connection between the boost device, the solenoid, and a power source. This allows the solenoid response time to be variable based on the characteristics of the boost device as well as the solenoid. By providing two different solenoid current rise and decay rates and by capturing and re-using energy stored in the solenoid, the inventive drive circuit enhances solenoid response and increases efficiency.
