Abstract: A method, controller, and internal combustion engine including the controller and operable in accordance with the method by: determining a temperature of a working liquid in an engine block circuit (31, 35) of the internal combustion engine (10), the working liquid comprising a cooling liquid or a lubrication liquid; operating the internal combustion engine (10); engaging a thermal load responsive to the temperature of the liquid being below a first temperature threshold, wherein engaging the thermal load comprises at least one of increasing a pumping load of the internal combustion engine (10), or changing an air/fuel ratio, thereby adding heat to the engine block circuit (31, 35); controlling the thermal load as a function of the temperature of the liquid; and disengaging at least a portion of the thermal load responsive to the temperature of the liquid being above the low temperature limit.

Abstract: 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.
