Abstract: An exhaust aftertreatment system includes an oxidation catalyst and a selective catalytic reduction (SCR) catalyst disposed in an exhaust stream of an internal combustion engine. A stay warm thermal management strategy is employed after warm-up of the aftertreatment system is complete to maintain the aftertreatment system above a temperature providing a desired performance threshold of one or more components of the aftertreatment system, such as the oxidation catalyst or the SCR catalyst.

Abstract: Systems and methods for correcting mass airflow sensor drift include an operation conditions module to interpret a base calibration function, a MAF sensor input value, and a current operating condition. A MAF correction module determines an expected MAF value in response to the current operating condition and a predetermined operating condition. The MAF correction module will also determine an adjusted MAF value in response to the expected MAF value, the base calibration function, and the MAF sensor input value. A MAF reporting module is structured to provide the adjusted MAF value.

Abstract: Methods and systems are disclosed for fuel drift estimation and compensation using exhaust oxygen levels and fresh air flow measurements. An actual fueling to the engine cylinders is determined from the exhaust oxygen level and fresh air flow to the internal combustion engine. The actual fueling is compared to an expected fueling based on the fueling command provided to the internal combustion engine. The difference between the actual fueling and expected fueling is fuel drift error attributed to changes or drift in the fuel injection system and is used to correct or compensate future fueling commands for the fuel drift.
