    摘要： A method for estimating an oxygen concentration in an intake manifold of a diesel engine utilizing exhaust gas recirculation includes monitoring engine operation, monitoring an exhaust gas recirculation valve, and monitoring an exhaust air fuel ratio. When the engine operates in steady state with the exhaust gas recirculation valve in the closed position, a volumetric efficiency for the engine is updated. A partial pressure due to exhaust gas recirculation within the intake manifold based upon the updated volumetric efficiency is determined, and an estimated oxygen concentration within the intake manifold based upon the partial pressure due to exhaust gas recirculation within the intake manifold and the exhaust air fuel ratio is determined Operation of the engine is controlled based upon the estimated oxygen concentration within the intake manifold.

    摘要： A method to control operation of an engine during a transition from a first to a second combustion mode is provided. The engine includes a controllable throttle valve, a variable valve actuation system for controlling openings and closings of intake and exhaust valves, and, an intake and an exhaust. Mass airflow, intake manifold pressure, and cylinder volume to operate the engine in the second combustion mode and meet an operator torque request are determined. Current states for mass airflow, intake manifold pressure, and cylinder volume are determined. An opening position of the controllable throttle valve and the openings and the closings of the intake and exhaust valves are controlled during the transition to the second combustion mode based upon differences between the current states for mass airflow, intake manifold pressure, and cylinder volume, and, the mass airflow, the intake manifold pressure, and the cylinder volume.

    摘要： A method for selecting a preferred combustion mode for an internal combustion engine operative in a plurality of combustion modes is described. The method includes selecting a combustion mode in terms of first and second engine parameters, and separating the engine operating region into zones defined by the first parameter. Each of the zones is further separated into sub-zones defined by the second parameter. A combustion mode is associated with each of the sub-zones. Operating states are determined for the first and second parameters. One of the zones is identified based upon the state for the first parameter. One of the sub-zones of the identified zone is identified based upon the state for the second parameter, along with a combustion mode associated with the identified sub-zone. The engine is controlled to the preferred combustion mode, depending upon hysteresis.
