ABSTRACT:
An efficient, economical, compact diesel particulate filter comprising a casing radially filled with a bundle of tubes comprising woven, braided, or knitted inorganic yarn, wherein each tube is at least about twice the length of the bundle, and is folded at one end to prevent exhaust from traveling through the hollow of the tube without passing through its wall.
