  • 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: 10760469
    Abstract: An aftertreatment system can include a radiation shield for reducing and/or redirecting radiative thermal energy. The aftertreatment system can include a first housing, a second housing, a first aftertreatment component, and the radiation shield. The first aftertreatment component is positioned within one of a first interior volume of the first housing or a second interior volume of the second housing. The radiation shield includes an attachment portion and a thermal barrier portion. The attachment portion is coupled to an exterior of the first housing or the second housing. The thermal barrier portion is structured to divert radiative thermal energy in a second direction different than a source direction of the radiative thermal energy.
