ABSTRACT:
An efficient, economical, compact diesel particulate filter comprising a casing with a plurality of concentric, spaced, perforated, supported, substantially rigid tubes substantially filling the casing radially, wherein the perforated surface of each tube is covered by a filtering element comprising substantially helically wound inorganic yarn, wherein each space between tubes is blocked at only one end of the tubes so that exhaust entering an unblocked space at one end of the casing passes radially inwardly and outwardly through filtering elements before exiting through an unblocked space at the other end of the casing.
