摘要： The exhaust from a diesel-fueled internal combustion engine (201) is treated by a lean NOχ trap (207). The maximum temperature used for desulfating the lean NOx trap (207) is kept relatively lower during early life and progressively increased as the trap (207) ages. Designing for adequate late life performance entails excess capacity during early life. The method utilizes the excess capacity available during early life to slow aging of the trap (207) and thereby extend the trap (207) lifetime. The method facilitates meeting durability requirements for diesel-powered vehicles with exhaust aftertreatment.

摘要： A lean NO x 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 NO x trap (105), reaching a critical value. The critical value is varied according to the demands currently being place on the exhaust aftertreatment system (103). In one embodiment, the critical value is set based on engine speed- load information. The method regenerates more frequently when exhaust aftertreatment demands are high and less frequently when demands are low. The method improves aftertreatment performance while reducing aftertreatment fuel penalty.

摘要： A power generation system comprising a LNT for exhaust aftertreatment. The LNT has an effective operating temperature range. When the LNT is near a limit of its effective operating temperature range, the transmission is used to select operating points that increase the LNT's effectiveness. Generally, these operating points reduce the exhaust flow rate, although other factors such as the exhaust temperature may also be taken into account in selecting the operating points. Preferably, the LNT's effective operating temperature range includes exhaust temperatures produced by the engine at its point of peak power output, whereby the LNT does not approach the limits of its effective operating temperature range except when the engine is at less than peak power. At lower power levels, it is generally possible to select operating points that provide lower exhaust flow rates than the flow rate occurring at the peak power level.
