A cargo transport rear frame includes a pair of posts, an upper cross member, and a rear bolster. The posts are spaced in a width direction, and extend in a height direction. The upper cross member extends along the width between the posts. The rear bolster extends between lower ends of the posts such that the rear bolster is spaced below the upper cross member. The posts, the upper cross member, and the rear bolster bound the rear cargo opening. The rear bolster has a first side facing in a forward direction, and the rear bolster has a second side facing in a rearward direction to be exposed to a rear side of the cargo transport rear frame. The rear bolster comprises a sheet metal stamping including a base surface and a relief embossed in the rearward direction from the base surface to form a loading dock engagement feature.

According to one embodiment, a flange joint for joining a first pipe to a second pipe includes an adapter coupled to the first pipe. The adapter includes a convex surface. The flange joint also includes a gasket with a first concave surface and a second convex surface. The first concave surface of the gasket is matingly engageable with the convex surface of the adapter. The second convex surface is matingly engageable with the second pipe. The gasket is supported on the first pipe. The flange joint further includes a clamp that includes a concave surface that is matingly engageable with the second pipe to secure the gasket to the adapter.

Spherical flange joint

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.

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.

Apparatus, method, and system for diagnosing reductant deposits in an exhaust aftertreatment system

In one non-limiting embodiment, an apparatus for treating exhaust includes a reductant injector, an aftertreatment component including a NOreduction catalyst, and a pathway for directing exhaust to the aftertreatment component. The pathway includes a constriction zone within which is positioned a mixing member. The constriction zone begins downstream of the reductant injector and upstream from the aftertreatment component. However, other embodiments, forms and applications are also envisioned.

Reductant material deposit reduction in exhaust aftertreatment systems

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.

According to one embodiment, a sensor module includes a sensor probe that has at least two arms coupled together at a central location with each of the at least two arms extending radially outwardly away from the central location. Each of the at least two arms includes one of a plurality of openings and an elongate opening extending radially along the arm. The at least two arms define fluid flow channels therein. The sensor module also includes at least one extractor coupled to the probe. The at least one extractor includes a fluid flow channel that is communicable in fluid receiving communication with fluid flowing through the fluid flow channel of at least one of the at least two arms. Further, the sensor module includes at least one sensor that is communicable in fluid sensing communication with fluid flowing through the at least one extractor.
