    摘要: A method controlling operation of an engine utilizing a number of preset operating parameters is provided. An operating mode of the engine is determined. An operating state of the engine is determined. A first plurality of engine parameter settings are retrieved from a memory in response to the determined operating mode and the determined operating state of the engine. The first plurality of engine parameter settings are applied to at least one control algorithm of the engine. A rate of soot accumulation from the engine is monitored. The rate of soot accumulation is compared to a predetermined soot accumulation rate threshold. A second plurality of engine parameter settings are retrieved from a memory in response to the monitored rate of soot accumulation exceeding the predetermined soot accumulation rate threshold.

    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.
