20120096833 | AFTERTREATMENT MOUNTING SYSTEM - 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. | 04-26-2012 |
20140044612 | After-Treatment System - An after-treatment system includes a Selective Catalytic Reduction (SCR) catalyst or a similar aftertreatment unit or brick that may be inserted into the opened end of a sleeve. The aftertreatment brick includes a substrate matrix with catalytic material that extends between a first face and a second face. A mantle is disposed around the substrate matrix and extends between a first rim proximate the first face and a second rim proximate the second face. The mantel may include a overhang extension that extends the first rim of the mantle beyond the first face of the substrate matrix. To enable retrieval of the SCR catalyst from the sleeve, a retrieval feature is disposed on a readily accessible, inner surface of the overhang extension. | 02-13-2014 |
20140174060 | System and Method for Accommodating Aftertreatment Bricks - One or more aftertreatment bricks are axially inserted through an opening in the first end of a tubular sleeve of an aftertreatment system. The aftertreatment brick includes a substrate matrix and a mantle disposed around the substrate matrix. The mantle further includes a lip arranged to extend through the opening of the sleeve. One or more channel pockets are secured proximate to the opening of the sleeve and oriented radially outward with respect to the sleeve axis. To retain the aftertreatment brick in the sleeve, a clamping assembly is used that includes a hook, a fastener, and a capture nut. The capture nut is installed and accommodated in the channel pockets. The hook engages the protruding lip of the aftertreatment brick and the fastener secures the hook to the capture nut received in the channel pocket. | 06-26-2014 |
20140175238 | System and Method for Installing Aftertreatment Bricks - 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. | 06-26-2014 |
20140178263 | System and Method for Retaining Aftertreatment Bricks - An aftertreatment system and method treats exhaust gasses produced by an internal combustion process or similar process. The system includes an aftertreatment module having at least one sleeve extending between a first end and a second end. One or more aftertreatment bricks may be axially inserted through an opening disposed in the first end of the sleeve. The aftertreatment brick may include an substrate matrix surrounded by a tubular, protective mantle. To prevent the aftertreatment bricks from unintentionally exiting the sleeve, a retention ring is releasably engaged with the first end of the sleeve. The retention ring may include a dimension that is less than a dimension of the opening in the first end so that at least a portion of the retention ring contacts the mantle of the aftertreatment brick. | 06-26-2014 |
20140208723 | CATALYTIC CONVERTER AND MUFFLER - A catalytic converter and muffler including a housing having an inlet disposed between a first end and a second end of the housing to introduce exhaust gases into an inlet chamber. A plurality of first exhaust treatment banks disposed between the inlet and the first end of the housing to allow the exhaust gases flow towards the first end from the inlet chamber into an end chamber. A mixing tube to direct the exhaust gases towards the second end from the end chamber into a flow distributor and a plurality of second exhaust aftertreatment banks and flow into an outlet chamber. At least one resonator chamber defined within the housing to attenuate noise in the exhaust gases. | 07-31-2014 |
20140260198 | EXHAUST AFTERTREATMENT SYSTEM - An exhaust aftertreatment module is provided. The exhaust aftertreatment module includes a housing having a first end and a second end. The at least one inlet is disposed between the first end and the second end and is configured to introduce an exhaust into the housing. A mixing tube is disposed downstream of the at least one inlet. The mixing tube is configured to direct the exhaust towards the second end of the housing. The exhaust aftertreatment module further includes a single bank of Selective Catalytic Reduction (SCR) catalysts disposed at an oblique angle to a longitudinal axis of the mixing tube. The single bank of SCR catalysts is configured to receive the exhaust redirected from the second end of the housing. | 09-18-2014 |
20140283528 | Aftertreatment Module and Method of Assembly - To assemble an aftertreatment module for use in the treatment of exhaust gasses and the like, an aftertreatment brick is inserted into a sleeve opening in a sleeve and advanced toward an opposite end of the sleeve. To retain the aftertreatment brick in the sleeve, the end of the sleeve can include a stop flange and the aftertreatment brick can include a mantle flange. The stop flange and the mantle flange can abut against each other to prevent further movement of the aftertreatment brick through the sleeve. To seal against exhaust gasses leaking though the module, a gasket can be disposed between the stop flange and the mantle flange. Exterior ribs disposed around the aftertreatment brick can assist concentric alignment between the flanges and gasket. | 09-25-2014 |
