    Abstract: A boss configured to mount a nitrous oxide sensor in an exhaust conduit is disclosed. The boss includes a first tier configured to contact with an exterior surface of the exhaust conduit, the first tier defined by a first diameter and a first height. The boss also includes a second tier extending from the first tier. The second tier is configured to be disposed within an interior space defined within the exhaust conduit. The second tier is defined by a second diameter and a second height. Further, the second diameter is sized smaller than the first diameter. The boss further includes a condensation protection feature configured to direct condensation away from the nitrous oxide sensor.

    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: 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.
