Frame filter for removal of particulates from internal combustion engine exhaust gases provides improved flow path and reduced leakage using multiple parallel alternating pockets sealed to filter housing

摘要

A frame filter (6) with multiple parallel, side by side, alternate open and closed pockets for the removal of particulates from gas, is formed as a rectangular panel, which is fitted into a cylindrical housing, using cover plates (21) and a seal arrangement (18). Side ribs (16) of the gas inlet pockets (10) are embedded into the seal, which is fused, welded or glued to the inner surface of the housing.
