  • Patent number: 10989093
    Abstract: Systems, methods, and apparatuses for adaptive regeneration of aftertreatment system components. The system may include an aftertreatment system and a controller. The controller is configured to access one or more parameters indicative of an ambient condition, determine a regeneration type of a regeneration process for a component of the aftertreatment system, determine an application in condition, and modify a parameter for the regeneration process for the component of the aftertreatment system. In some instances, the controller initiates the regeneration process. In some instances, the one or more parameters include an ambient air temperature, a reductant tank temperature, or a particulate matter sensor temperature. In some instances, the modified parameter includes a target regeneration temperature, a regeneration duration, a dwell time between regeneration process, a threshold value for the regeneration process, or a minimum regeneration temperature.

  • Patent number: 10662847
    Abstract: An apparatus and method for controlling engine start/stop operations based at least in part on considerations relating to the thermal management of an exhaust gas after-treatment system. A control system may monitor and/or predict conditions and/or properties of the after-treatment system, including conditions related to the thermal management of a selective catalytic reduction system and the properties of an exhaust gas stream that has been released from an internal combustion engine and into the after-treatment system. Such conditions may be evaluated in determining whether the thermal management of the after-treatment system is at, or will be in, a condition that may accommodate a start/stop operation of the internal combustion engine with minimal, if any, adverse impact on the thermal management of the after-treatment system. Such an evaluation may, in at least certain situations, provide at least a consideration as to whether to de-activate or activate start/stop operations.
