Abstract: A method for forming a conduit with a radial flange for forming part of a beaded coupling by: positioning a conduit blank in a forming die, wherein the forming die defines a radially extending recess; inserting a forming post in the conduit blank to define an annular space therebetween; inserting a flexible material in the annular space between the post and the conduit; placing a sleeve in a bearing relationship with the flexible material; compressing the flexible material between the post and the sleeve to force the flexible material against the conduit to expand the conduit outward into engagement with the radially extending recess in the forming die to form an annular flange; and releasing compression on the flexible material.

Abstract: An exhaust gas treatment system for an internal combustion engine may have a reductant delivery system that delivers reductant to an exhaust stream in an exhaust aftertreatment system. A temperature sensor may be positioned in or near the flow of reductant and exhaust to measure the temperature of the reductant and exhaust. A change in temperature over time, such as an increase, decrease, or change in variation amplitude, may indicate the presence of a reductant deposit in the system. Detection of the deposit may initiate a regeneration cycle in which the operating characteristics of the system change to eliminate the reductant deposit to prevent it from hindering the performance of the exhaust aftertreatment system.

Abstract: 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.
