Abstract: An aftertreatment system and method treats exhaust gasses produced by an internal combustion process or a similar process. The aftertreatment system includes an aftertreatment module having a sleeve extending between a first end and a second end. One or more aftertreatment bricks are axially inserted into a sleeve opening disposed in the first end of the sleeve. To prevent the aftertreatment bricks from unintentionally exiting the sleeve, a captive ring is disposed around the first end of the sleeve as a loose fitting collar. The captive ring is restrained on the sleeve by a circumferential bead protruding about the first end. The captive ring can couple with a retention ring placed adjacent the first end. When coupled to the captive ring, a portion of the retention ring extends partially across and blocks the sleeve opening, preventing the aftertreatment brick from exiting the sleeve.

Abstract: An exhaust gas aftertreatment system is disclosed. The system may include an inlet to receive an exhaust gas produced by an engine and a first section to receive the exhaust gas from the inlet. The system may include a mixing tube to receive the exhaust gas from the first section and a reductant injector to inject a reductant into the mixing tube. The system may include a second section to receive the exhaust gas from the mixing tube and to facilitate mixing of the reductant and the exhaust gas after the exhaust gas exits the mixing tube and a diffuser to receive the exhaust gas from the second section. The system may include a plurality of catalysts to receive the exhaust gas from the diffuser and at least one outlet to receive the exhaust gas from the plurality of catalysts.

Abstract: An aftertreatment module is disclosed. The aftertreatment module may include a housing and a mounting plate within the housing that forms an inlet chamber and an outlet chamber. The aftertreatment module may include an inlet for exhaust gas from a combustion engine to flow into the inlet chamber and an outlet through a top plate of the housing for the exhaust gas to flow from the outlet chamber, wherein the outlet comprises a plurality of perforations. The aftertreatment module may include an outlet sensor mounted on the outlet to obtain information relating to the exhaust gas as the exhaust gas flows from the outlet chamber and a set of catalysts mounted to the mounting plate to treat the exhaust gas as the exhaust gas flows from the inlet chamber to the outlet chamber. The aftertreatment module may include a drain port through a side plate of the housing.

Abstract: A nozzle including a nozzle body having a proximal end and a distal end. The proximal end includes at least a first inlet and a second inlet, and the distal end includes an outlet. An inner tube extends in a direction along a central longitudinal axis of the nozzle and at least partly defines a first channel fluidly connected to the first inlet and a second channel fluidly connected to the second inlet. The second channel fluidly connects to the first channel via one or more orifices extending through the inner tube.

Abstract: 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.
