摘要： The present invention provides for a system and process for enhancing internal combustion engine aftertreatment applications by superheated fuel injection. The system includes a fuel supply upstream of a fuel injector of an aftertreatment application. The system also includes a heater for heating the fuel in the fuel supply. A temperature controller can be used to maintain the heated fuel in a liquid form. When liquid fuel in the pressurized fuel supply is heated, then upon exiting the injector the pressure of the fuel drops rapidly, resulting in atomization of the liquid. The vaporized fuel thereby produced is comprised of extremely small droplets and is elevated in temperature, which reduces the possibility of condensation on internal surfaces of the aftertreatment system. This fine droplet size and resistance to condensation enhances the NOx conversion efficiency of adsorbers. Problems related to premature aging of catalysts and fuel penalties can also be reduced.

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： The present invention provides for an NOx adsorber aftertreatment system for internal combustion engines which utilizes adsorber catalysts arranged in parallel. The exhaust flow from the engine is divided in a predetermined ratio between the two catalysts during lean operation (e.g. 50-50). 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 is to be regenerated (e.g., 20% through the leg to be regenerated, 80% of the flow to the other leg). A quantity of hydrocarbon is injected into the reduced-flow 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 flow distribution between the parallel legs is reversed, and the other catalyst leg is regenerated while the other side (which is now clean) receives the majority of the exhaust flow. Another advantage of the present invention is that since NOx is being stored in one leg while the other leg is being regenerated, the regeneration operation can be performed for a longer period of time, resulting in greater regeneration efficiency. Once both catalyst legs have been regenerated, the exhaust flow is adjusted back to normal (e.g. 50-50) until the catalysts are again ready for regeneration and reduction.
摘要翻译：本发明提供一种利用并联排列的吸附剂催化剂的内燃机的NOx吸附器后处理系统。来自发动机的废气流在稀薄运行期间以两个催化剂之间的预定比例被分配（例如50-50）。在预定的再生时间（例如，当吸附剂催化剂充满20％时），废气流通过待再生的平行腿减少（例如，通过待再生的腿20％，再生的80％流向另一条腿）。为了使混合物富集，将一定数量的烃注入到减流气流中。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。一旦腿已被再生，则平行腿之间的流动分布相反，并且另一个催化剂腿被再生，而另一侧（现在是清洁的）接收大部分排气流。本发明的另一个优点是，由于在另一条腿正在再生的同时，将NOx储存在一条腿上，所以可以进行更长时间的再生操作，从而获得更高的再生效率。一旦两个催化剂支路已被再生，排气流量将被调整回正常（例如50-50），直到催化剂再次准备再生和还原。

摘要： A monitoring system is used to monitor the location and orientation of a downhole tool assembly by detecting an output signal. The downhole tool assembly has a beacon assembly with one or more configurable operation parameters. A transmitting assembly transmits an operation instruction signal to the beacon assembly to configure the operation parameters. The detected operation instruction signal is processed by the beacon assembly and the operation parameter is configured. The transmitting assembly may be separate from the monitoring system and have an input assembly. The input assembly allows the operator to input predetermined operation parameters into the transmitting assembly that are then transmitted to the beacon assembly. In a preferred embodiment, the configurable operation parameters may include the intensity and/or frequency of the output signal, the calibration and resolution of orientation sensors, and the rate at which data is transmitted from the beacon assembly.
