    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 and system for adaptively controlling a diesel engine to account for variations in the cetane number of the diesel fuel being used. An engine controller includes various control modules with algorithms for estimating the fuel cetane number, or determining the ignition delay that the engine is experiencing, or both. With this information, the controller can adjust the amount of exhaust gas recirculation that is used, thus varying the amount of oxygen that is available in the intake charge to burn the fuel. The controller can also adjust the timing of the fuel injection event, as another way of altering the nature of combustion. Using these techniques, the controller can optimize the engine operation based on the fuel currently being used.

    摘要： An engine includes an exhaust gas recirculation circuit, an air throttle system, and a charging system. A method to control the engine includes determining a feed forward control command for a first selected one of the exhaust gas recirculation system, the air throttle system, and the charging system based on an inverse flow model of the first selected system. This includes monitoring a first input based upon an effective flow area of the first selected system, monitoring a second input based upon a pressure value within the first selected system, and determining the feed forward control command for the first selected system based upon the first input and the second input. The first selected system is controlled based upon the feed forward control command for the first selected system.

    摘要： A method for determining a cylinder air charge for an internal combustion engine includes determining engine operating parameters including an intake air charge density, an engine delta pressure as a ratio of an intake manifold pressure to an exhaust pressure, and an engine speed. An open-throttle volumetric efficiency corresponding to the engine operating parameters is determined, and a closed-throttle volumetric efficiency corresponding to the engine operating parameters is also determined. The cylinder air charge is determined using a selected one of the open-throttle volumetric efficiency and the closed-throttle volumetric efficiency.
