Abstract: 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.

Abstract: An apparatus and system are disclosed for ensuring proper assembly of an exhaust system. Ensuring proper assembly of an exhaust system is accomplished by providing an inflow exhaust subassembly for receiving engine exhaust, at least one intermediate subassembly that selectively mates and rotationally aligns with the inflow subassembly and receives engine exhaust therefrom, the at least one intermediate subassembly further configured to selectively mate according to a pre-selected alignment with an outflow subassembly, and the outflow subassembly configured to receive engine exhaust from the at least one intermediate subassembly. In certain embodiments, the at least one intermediate subassembly comprises a plurality of intermediate exhaust subassemblies each configured to selectively mate with adjacent subassemblies according to a pre-selected order and alignment.

Abstract: Gas treatment systems are described that allow for modular development of gas treatment systems, for example exhaust gas aftertreatment systems, using generally standardized parts. A number of subsections are provided, including a treatment subsection containing an exhaust gas treatment device for treating exhaust gas. The treatment subsection is designed to be connectable to an inlet subsection, an outlet subsection, or other subsections in a manner that allows the positions, both longitudinally and rotationally, of the treatment subsection relative to adjacent subsections to be adjusted as required during assembly. This permits an infinite number of length and/or clocking configurations for the aftertreatment system to be manufactured.
