Abstract: A power generation system having a fuel reformer positioned inline with an engine exhaust stream. A transmission controller selects torque ratios and thereby operating points for the engine in order to facilitate start-up or operation of the fuel reformer. In one embodiment, the controller selects operating points to heat the exhaust and thus the reformer prior to starting the reformer. In another embodiment, the controller selects operating points to reduce or limit the oxygen concentration in the exhaust during denitration or desulfation of a LNT. In a further embodiment, the controller selects operating points to reduce a fuel penalty for a regeneration. The fuel penalty includes at least a contribution associated with consuming excess oxygen in the exhaust.

Abstract: A method is provided for regenerating a LNT (13) in a diesel engine (9) exhaust aftertreatment system (7). Typically, the aftertreatment system (7) comprises a fuel reformer (12), a LNT (13), and a SCR catalyst (14) 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 (12) 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.

Abstract: 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

Abstract: 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.

Abstract: An exhaust line fuel injection system (1) and associated methods of operation and control are disclosed. The fuel passes through a regulating valve (11, 60, 70, 80) having an inlet (62, 81) connected to a pressurized fuel source (20) and an outlet (63, 82) connected to an exhaust system fuel supply line (15). The exhaust system fuel supply line (15) is connected to a nozzle (12, 40, 50, 60), which generally comprises a check-valve and is configured to inject the fuel into the exhaust line (30, 100). Using a pressure measuring device (13), an indication of the exhaust system fuel supply line pressure is obtained. A controller (14, 119) provides control over the flow regulating valve (11, 60, 70, 80) using feedback from the pressure indication and a predetermined relationship between the flow rate through the nozzle (12, 40, 50, 60) and one of the exhaust system fuel supply line pressure and the pressure drop across the nozzle (12, 40, 50, 60). The method can be implemented with a single pressure measuring device (13). The same pressure measurements, especially their frequency spectrum, can be used to detect system faults.

Abstract: Partial denitrations are made practical by an SCR catalyst (13) placed downstream of a NOx adsorber (12) . The SCR catalyst permits partial denitrations to be extended to where a favorable fuel penalty rate presented by driving conditions can be utilized to a sufficient extent that the benefit of the favorable conditions is not offset by the increased start-up fuel penalty associated with conducting opportunistic partial denitrations. In specific embodiments, regenerations are based on low oxygen concentrations, condition existing while shifting gears, and throttling events for a diesel engine (5) with a throttled air supply. The methods flexibly take advantage of driving conditions to reduce fuel penalties associated with regenerations. In one embodiment, driving conditions include future conditions predicted based on GPS and map data .
