    摘要： A rotary device is coupled to the rotary mechanism of a turbocharger for selectively adding torque to and subtracting torque from the rotary turbocharger mechanism. A controller causes the rotary device to apply torque to the rotary turbocharger mechanism which causes the compressor to operate at a power level which creates a target pressure in the intake manifold different from existing pressure in the intake manifold.

    摘要： A method of controlling an engine based upon airflow is provided. A request for a desired torque output of the engine is received. A first amount of fuel required to generate the desired torque is retrieving from a memory. An amount of airflow required to combust the fuel required to generate the desired torque at a predefined air/fuel ratio is calculated. A first amount of EGR required to produce a predefined amount of NOx emissions is calculated. The amount of airflow required to the first amount of EGR required is added. The total of the airflow and the first amount of EGR are compared to a volume available in a cylinder. At least one of the first amount of fuel delivered and the first amount of EGR provided is modified when the total of the airflow and the EGR exceeds the total volume available in the cylinder.

    摘要： A method of controlling a variable geometry turbocharger is provided. A predefined desired boost pressure of a turbocharger is obtained from a memory. A predefined desired mass flow rate in an intake manifold of an engine is obtained from the memory. A theoretical amount of power required by the turbocharger to generate the desired boost pressure and the desired mass flow rate is calculated. An actual mass flow rate in the intake manifold is determined. An actual amount of power required by the turbocharger to generate the desired boost pressure and the actual mass flow rate is calculated. At least one adjustable vane of the turbine of the turbocharger is adjusted to allow the theoretical amount of power required of the turbocharger to generally equal the actual amount of power by adjusting the boost pressure.

    摘要： A method is provided for operating an engine to limit soot emissions during fuel-enriched operation. The method includes operating the engine using a first fuel injection pattern and timing to inject fuel into a combustion chamber of the engine. The method further includes receiving a request for an increased engine power output and operating the engine using a second fuel injection pattern and timing to inject more fuel into the combustion in response to the request for the increased power output, where the second fuel injection pattern and timing is configured to minimize soot emissions during enriched fuel operations, such as during transient operations.
