Abstract: An aftertreatment module includes a catalytic brick having upstream and downstream flanges sized to extend over potential leak flow paths between bricks. Additionally, an aftertreatment module has an array of similarly flanged bricks to reduce leakage through all interfaces between adjacent bricks. A frame for holding the array of bricks includes flow modulators to restrict leakage through an interface between the frame and at least one side surface defined by the array of bricks.

Abstract: An aftertreatment system of an engine is disclosed. The aftertreatment system includes a housing. The aftertreatment system also includes a Selective Catalytic Reduction (SCR) catalyst provided within the housing. The aftertreatment system further includes an exhaust duct associated with the SCR catalyst. The aftertreatment system includes a sampling flute provided within the exhaust duct. The aftertreatment system also includes a NOx sensor at least partly enclosed by a first end of the sampling flute. The aftertreatment system further includes a spring member. The spring member is joined to the sampling flute and the exhaust duct.
