Abstract: A canister assembly for use in an exhaust gas aftertreatment device comprises a cylindrical shell defining a cylindrical axis, a radial direction, and a circumferential direction, a top end and a bottom end. A flow tube is inserted into the top end of the cylindrical shell and terminates short of the bottom end of the cylindrical shell, defining an exit of the flow tube. A mixing bowl member including a symmetrical annular shape about the cylindrical axis and defining a mixing bowl pocket is attached at the bottom end of the cylindrical shell.

Abstract: Exhaust gas systems and methods are disclosed. A system includes an extensible duct assembly to communicate an exhaust gas from an internal combustion engine to an exhaust gas receiver. An angularly positionable ball joint assembly may be coupled to the duct assembly to fluidly and sealably couple the duct assembly to at least one of the outlet and the exhaust receiver. A method of installing an exhaust gas system includes presenting a first portion of the exhaust gas system to one of an exhaust gas outlet and an exhaust gas receiver, and positioning a second portion of the exhaust gas system relative to the other of the exhaust gas outlet and the exhaust gas receiver. The first portion and the second portion may be adjusted to achieve an alignment, and the first portion and the second portion may be sealably coupled to fixedly retain the alignment.
