Abstract: A method of manufacturing a subassembly for an exhaust treatment device includes providing a metal sheet including first and second apertures having respective first and second sizes, and a one-piece pipe including first and second linear portions having respective third and fourth sizes. The method further includes defining the first size based on a first difference between the first size and the third size being less than or equal to a predetermined value, and defining the second size based on manufacturing tolerances of the pipe to assure that the second linear portion will pass through the second aperture while the first linear portion passes through the first aperture. The method further includes fixing the first linear portion to the sheet, expanding the second linear portion from the fourth size to an enlarged size less than or equal to the predetermined value, and fixing the second linear portion to the sheet.

Abstract: A mixer for mixing an exhaust flow with a fluid injected into an exhaust pipe includes a tubular housing having a reduced size center portion positioned between first and second ends. The housing includes circumferentially spaced apart apertures extending through the center portion. A first mixing element includes a first peripheral portion positioned within one of the apertures and a second peripheral portion positioned within another one of the apertures. A second mixing element includes third and fourth peripheral portions positioned within other apertures of the housing.

Abstract: A mixer for mixing an exhaust flow in an exhaust pipe includes a tubular housing having a first end, a second end and a center portion positioned between the ends. The center portion has a reduced size in relation to at least one of the first and second ends. The housing includes circumferentially spaced apart apertures extending through the center portion. A mixing element includes a body having a first peripheral portion and a second peripheral portion. The first peripheral portion is fixed to the center portion at a location adjacent to one of the apertures. The second peripheral portion is fixed to the center portion at a location adjacent to another one of the apertures.
