Abstract: An aftertreatment brick can be installed in a brick compartment of an aftertreatment module with a releasable securing assembly. The releasable securing assembly includes a first bracket, a second bracket, and a band clamp. The first bracket is installed in the brick compartment proximate a port. The aftertreatment brick is placed on the first bracket adjacent the port and the second bracket is placed about the aftertreatment brick above the first bracket. The band clamp is slid over the first and second brackets and tightened to secure the brackets about the brick.

Abstract: An exhaust aftertreatment system including a housing with two or more inlets configured to receive separate entering exhaust streams from an engine. The system may include two or more first exhaust treatment devices, each configured to receive one of the separate entering exhaust streams in a first direction. The system may further include two or more redirecting flow passages configured to combine the separate exhaust streams into a merged exhaust stream that flows in a second direction about 180 degrees from the first direction and an intermediate flow region configured to divide the merged exhaust stream into two or more separate exiting exhaust streams. The system also may also includes two or more second exhaust treatment devices, each configured to receive one of the separate exiting exhaust streams in a third direction about 90 degrees from the second direction.

Abstract: A reductant dosing system for a machine having an engine and an exhaust system is disclosed. The reductant dosing system has a tank configured to hold a reductant, a dosing arrangement, and a supply passage connecting the tank to the dosing arrangement. The reductant dosing system also has a purging arrangement configured to direct purge fluid to at least one of the dosing arrangement and the supply passage, and a valve configured to allow reductant to pass from the tank to the supply passage and to inhibit purge fluid from entering the tank.

Abstract: An exhaust aftertreatment module comprising a plurality of mounts for connecting the module to a surface. The mounts are arranged in a radial pattern around a central location of the module. The mounts also have a direction of travel aligned with a radial direction of expansion that passes through the central location.
