    摘要： A system for controlling exhaust emissions produced by an internal combustion engine includes an engine controller having an emission manager configured to produce a base emission level cap command, corresponding to a maximum allowable emission level of the engine, as a function of at least altitude and ambient temperature. The emission manager may also include one or more auxiliary emission control devices (AECDs), and the emission manager is further operable in such cases to determine a maximum allowable emission level associated with each active AECD. A final emission level cap command is determined as a function of the base emission level cap command and the maximum allowable emission level associated with each active AECD. The emission manager is further operable to produce a protection state data structure that includes information relating to the operational status of each AECD.

    摘要： A combustion manager portion of an engine controller is responsive to ambient air density and engine temperature signals to schedule charge flow and EGR fraction commands. The combustion manager includes a data structure determination block operable to select an appropriate engine speed/engine fueling data structure based on air density and engine temperature information as well as on desired emissions level and engine operating state (i.e., steady state or transient) information. Charge flow and EGR fraction determination blocks are, in turn, responsive to current engine speed and engine fueling information to produce compute the EGR fraction and charge flow commands as a function of the selected engine speed/engine fueling data structures.

    摘要： A method and system for controlling an exhaust temperature for an internal combustion engine is disclosed. The method and system include determining a range of acceptable charge flows within the internal combustion engine to meet a desired exhaust temperature. The method and system further include controlling the charge flows to fall within the range. Control strategies to utilize the charge flow as a lever to control turbine outlet temperature are disclosed. These strategies utilize the inversion of the cylinder outlet temperature virtual sensor as well as a new turbine outlet temperature virtual sensor to determine the charge flow required to achieve the desired turbine outlet temperature given the current turbine inlet and outlet pressure, SOI, charge pressure, charge temperature, fueling, and engine speed.

The control parameters may correspond to one of the number of unconstrained solution parameters or to the number of solution parameters.

    摘要： A system is provided for limiting engine exhaust temperature to a maximum temperature limit. The system is operable to limit either a first or a second fueling parameter in accordance with an engine exhaust temperature estimation model. An engine exhaust temperature-limited fueling command is computed from the respective fueling parameter, and fuel supplied to the engine is limited thereby in order to maintain the actual engine exhaust temperature below the maximum temperature limit. In one embodiment, the engine exhaust temperature model is based on current values of engine speed, intake manifold temperature, mass charge flow, default fuel command parameters, and a first set of model constants. In an alternative embodiment, the engine exhaust temperature model is based on current values of engine speed, intake manifold temperature, intake manifold pressure, mass charge flow, default fueling parameters, and a second set of model constants including a lower heating value of fuel constant.
