A lean NOX trap is a diesel exhaust aftertreatment system is selectively denitrated in a manner that addresses unreliability of NOX sensor data. According to one concept, data from a NOX sensor is ignored or given decreased weight in a period immediately following a denitration. According to another concept, denitration is made contingent on both a first and a second criteria being met. The first criteria relates to the amount of NOX stored in the LNT or remaining NOX storage capacity of the LNT. The second criteria relates to the current performance of the exhaust treatment system, or a portion thereof, as determined from one or more measurements of NOX concentration in the exhaust. This reduces premature denitrations and associated unnecessary fuel expenditures resulting from inaccurate NOX concentration data and transient events

VALVE FOR ALLOCATING AVAILABLE FLUID TO HIGH PRIORITY FUNCTIONS OF A HYDRAULIC SYSTEM
A hydraulic system (10) has high priority hydraulic functions (17,18,19) connected to a primary supply line (15) that receives pressurized fluid from a source and low priority hydraulic functions (20) connected to secondary supply line (16).

A lean NOx trap (105) is a diesel exhaust aftertreatment system (103) is selectively denitrated based on a measure relating to the state and/or the performance of the exhaust aftertreatment system (103), or a portion thereof comprising the lean NOx trap (105), reaching a critical value. The critical value is varied according to the demands currently being place on the exhaust aftertreatment system (103).

A lean NOX trap (105) is a diesel exhaust aftertreatment system (103) is selectively denitrated when a measure relating to NOX loading, remaining NOX storage capacity, or performance of the exhaust aftertreatment system (103) or a portion thereof comprising the lean NOX trap (105) reaches a critical value. The critical value is determined based in part on conduciveness of current conditions to regenerating the lean NOX trap (105). Accordingly, denitration is scheduled based on a balance between the urgency of the need to regenerate and conduciveness of current conditions to regeneration. The stopping point for regeneration can also be selected based on conduciveness of current conditions to regeneration. The method maintains exhaust aftertreatment performance while reducing regeneration fuel penalty.

The inventors' concept relates to controlling a power generation system (100) having an exhaust aftertreatment system comprising a fuel reformer (104) and an LNT (105) in series. Over the course of a desulfation, a fuel injection upstream of the fuel reformer (104) is pulsed to create alternating lean and rich phases and control the LNT (105) temperature. The LNT (105) temperature is controlled by manipulating a minimum temperature for the fuel reformer (104) at the end of the lean phase, a length of the lean phase, or a pulse frequency. Preferably, the rich phases end when the fuel reformer (104) reaches a predetermined maximum temperature. The method is effective in regulating the fuel reformer (104) temperature while accurately controlling the LNT (105) temperature.

One of the inventors' concepts relates to controlling a temperature of a diesel exhaust aftertreatment device, such as a DPF or a fuel reformer, in which combustion is taking place. The concept is to inject reductant to combust in an upstream device, thereby removing oxygen in the exhaust and limiting combustion in the downstream device. The same total amount of heat may be generated, but the distribution is different and limits temperatures in the downstream device. The temperature limiting effect may be through one or more of the thermal storage capacity of the upstream device and or other upstream devices, the additional heat loss to the surroundings due to higher temperatures upstream in the exhaust system, or the benefit of a more uniform distribution of heat in the downstream device, which mitigates local hot spots. This concept may be used in a temperature control system.
