    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： An internal combustion engine operating at a lean air/fuel ratio includes a reductant injection system configured to dispense reductant into an exhaust gas feedstream upstream of a selective catalytic reduction device. The reductant injection system includes a reductant delivery system fluidly coupled to a reductant dispensing device that is configured to dispense the reductant. A method for monitoring the reductant injection system includes commanding the reductant dispensing device to dispense reductant at a prescribed reductant flowrate, controlling the reductant delivery system to a preferred operating state, monitoring operation of the reductant delivery system and estimating a reductant flowrate as a function of the monitored operation of the reductant delivery system, and diagnosing operation of the reductant injection system as a function of the prescribed reductant flowrate and the estimated reductant flowrate.

    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.
