    摘要： A method for controlling operation of an internal combustion engine determines an estimated NOx value as a function of at least one engine operating parameter. The method also determines an actual NOx value using a NOx sensor positioned in an exhaust gas stream of the internal combustion engine. The method detects at least one condition indicative of whether or not the actual NOx value is accurate. The actual NOx value is used for controlling engine operation when the at least one condition indicates that the actual NOx value is accurate, while the estimated NOx value is used for controlling engine operation when the at least one condition indicates that the actual NOx value is inaccurate.

    摘要： A method for determining the degree of saturation of a solid ammonia storage material in a storage unit includes activating a heater to release ammonia from the storage material until the pressure of the storage unit reaches a predetermined pressure. The method then deactivates the heater and determining a decay rate of the pressure of the storage unit while the heater is deactivated. The method estimates the degree of saturation of the ammonia storage medium in response to the decay rate. According to some embodiments, determining the decay rate may include measuring the time required for the pressure of the storage unit to drop from a first pressure threshold to a second pressure threshold.

    摘要： A system for storage and dosing of ammonia includes solid ammonia storage material capable of binding and releasing ammonia reversibly by adsorption/absorption. The system includes a start-up storage unit and a main storage unit, both of which hold ammonia storage material. A start-up heating device is arranged to heat the start-up storage unit to generate gaseous ammonia by thermal desorption from the solid storage material. A main heating device arranged to heat the main storage unit to generate gaseous ammonia by thermal desorption from the solid storage material. A controller modulates operation of the heating devices such that the main and start-up heating devices are not simultaneously activated.

    摘要： A method for controlling injection of a reductant into an exhaust system of an internal combustion engine, which includes measuring temperature at a plurality of locations in the exhaust system relative to an SCR catalyst, determining an average temperature as a function of the measured temperatures, and controlling injecting of a reductant into the exhaust upstream of the catalyst as a function of the average temperature. The average temperature may be a weighted average where temperature measurements from at least some locations upstream of the SCR catalyst may be assigned greater weight than temperature measurements proximate the SCR catalyst.
