    摘要： A system for controlling the transient torque output of a multicylinder, variable displacement, spark-ignited, fuel injected automotive internal combustion engine during periods when the effective displacement of the engine is being changed includes a spark timing controller, a throttle controller for positioning an intake air throttle, an engine cylinder operator for deactivating and reactivating at least some of the engine's cylinders, and an engine controller having a processor for selecting the number of cylinders for operation and for operating the spark timing controller, the throttle controller, and the cylinder operator so that during any transition from operation with a first number of activated cylinders to operation with a second number of activated cylinders, the processor will alter the spark advance and control the amount of air entering the engine cylinders so that the torque output of the engine will remain relatively unchanged during the transition.

    摘要： A powertrain controller controls the burned gas recycling rate of an engine as a function of a desired burned gas recycling rate and an actual burned gas recycling rate. The powertrain controller generates a tractive effort request value which is indicative of a force desired by the driver at the wheels of the vehicle. An engine load request value is generated as a function of the tractive effort request value and vehicle speed and is used, along with an actual load value, which is indicative of actual engine load, to generate the desired burned gas recycling rate. The tractive effort request value and other vehicle powertrain control variables are generated according to an optimization process. The burned gas recycling system of the engine may take the form of a Delta Pressure Feedback (DPFE) Exhaust Gas Recirculation (EGR) system or a variable position camshaft system.
