A selective catalytic reduction system may include a single housing defining a single centerline axis. The selective catalytic reduction system may also include a diesel particulate filter disposed within the single housing and having a DPF center axis aligned with the single centerline axis. The selective catalytic reduction system may also include an SCR catalyst disposed within the single housing and having a center axis aligned with the single centerline axis. In some implementations, the diesel particulate filter may include one or more SiC filters. In some implementations, the SCR catalyst may include one or more extruded SCR catalysts.

Single module integrated aftertreatment module

An aftertreatment subsystem includes first and second mounting interfaces, a fluid inlet and fluid outlet interface, and aftertreatment components, each having a central axis and axial extent. The central axes for the aftertreatment components are substantially parallel. End caps define fluid chambers that fluidly couple upstream aftertreatment component outlets with downstream aftertreatment components inlets. The end caps are positioned at a first or second end of the aftertreatment components. A first bracket joins the aftertreatment components at an axial position closer to the first end than to a center of the axial extent of any of the aftertreatment components and a second bracket joins the aftertreatment components at an axial position closer to the second end than to the center of the axial extent of any of the aftertreatment components. The first mounting interface is on the first bracket, and the second mounting interface is on the second bracket.

Aftertreatment manifold device

According to one representative embodiment, an exhaust aftertreatment component that includes a housing that defines an interior cavity through which exhaust gas is flowable. The housing includes an inner body, an outer body, and a space defined between the inner and outer bodies. The component also includes an insulation pack that is positioned within the space. The insulation pack includes insulation media encapsulated by a flexible fabric. The insulation pack further includes an at least partially rigid member that has a rigidity greater than a rigidity of the insulation media and flexible fabric.

Apparatus, system, and method for insulating an exhaust aftertreatment component

A vertical exhaust water trap assembly has an outer housing and an internal housing or exhaust tube defining an annular water collection spaced therebetween bypassing a central exhaust flow area.
