Abstract
A diesel exhaust filter construction includes a rectangular filter block, an elongated non-rectangular jacket with oval cross section, and support structure supporting the filter block in a center of the jacket. The support structure includes shielding components forming an insulating air gap with the jacket around the filter block (including a double-layered air gap in 'hot' areas), and further includes support structure slidably supporting one end of the filter block to accommodate dissimilar thermal expansion. The structure further includes baffling components with angled surfaces directing input exhaust gases along efficient flow paths from an inlet cone into front, rear, and opposite sides of the filter block and further directing output exhaust gases from top and bottom sides of the filter block toward a longitudinally-centered outlet cone. Some components are identical is shape and size for use in different locations on the construction, thus simplifying tooling.
