摘要： An internal combustion engine system includes a control system with a monitoring mechanism producing data of engine operating state within a BMEP/speed envelope, and an electronic control unit structured to output a control command to vary at least one of a fuel delivery property or an air delivery property in the engine based on the data. Outputting the control command switches the engine between or among combustion modes that each satisfy different calibration criteria for optimizing aftertreatment function.

摘要： A system includes an exhaust aftertreatment system operatively coupled to an engine. The exhaust aftertreatment system includes an exhaust aftertreatment component. A flow sensor is structured to provide an exhaust flow rate value of exhaust gas exiting the engine. A temperature sensor is structured to provide an exhaust temperature value of the exhaust gas proximate the exhaust aftertreatment component. A controller includes an exhaust conditions circuit structured to interpret the exhaust flow rate value via operative communication with each of the flow sensor, and to interpret the exhaust temperature value via operative communication with the temperature sensor. A regeneration time circuit is structured to determine a regeneration time value based on each of the exhaust flow rate value and the exhaust temperature value via a regeneration time lookup table. A regeneration control circuit is structured to control regeneration of the exhaust aftertreatment component based on the regeneration time value.
