A device that filters particulate matter from the exhaust stream of an engine includes a supporting structure with an elongate support, and a filter sleeve disposed within an exterior sleeve; a filter sleeve comprising a tubular shaft of filter material, the shaft having an open first end, and a closed second end; an exterior sleeve comprising a tubular shaft that defines an internal cavity that is sized and proportioned to receive the filter sleeve, the tubular shaft having an open first end, and a substantially closed second end, the substantially closed second end having a hole for filtered exhaust gases to pass through; and an attachment member that mounts the exterior sleeve to the supporting structure.

A structure of a metal fiber constituting a filter is set to a structure in which a cross-sectional shape of the metal fiber is a curved or bent shape and an outer member and an inner member having a linear expansion coefficient greater than that of the outer member are bonded to each other. Accordingly, the metal fiber is deformed to warp to the outer member side in the length direction thereof when the temperature of the metal fiber increases. When a amount of deformation per unit temperature of the metal fiber is defined as a deformation rate, a amount of change of the deformation rate per unit time changes at a predetermined deformation temperature with the increase in temperature. The deformation temperature is set to a temperature higher than a target temperature of a filter regenerating process.

The cooling device for a power source for a ship propulsion device that pumps up cooling water, from which foreign matters with sizes that cause clogging of a cooling water route have been removed, supplies the cooling water to a cooling water passage (30), and discharges the cooling water to outside after cooling a power source (10) includes: a filtration device (40, 40A, 40B) provided in the cooling water route to filtrate foreign matters remaining in the cooling water, and the filtration device is of a cartridge type that incorporates a filter (45, 72) for filtration disposed in a main water passage (P1) and a valve member (46, 66) configured to open and close a bypass water passage (P2) and that is configured such that in a case in which clogging occurs in the filter, the valve member opens to cause the cooling water to flow via the bypass water passage.

Apertured polymeric layers, sheets, mesh or films are provided for a variety of different applications. A polymeric sheet comprises at least one polymer layer having one or more apertures for flow of gas or liquid therethrough, and a plurality of nanoparticles disposed within the polymer sheet such that the nanoparticles are disposed between a first surface of the polymer sheet and a second surface opposite the first surface. The nanoparticles filter contaminants passing through the polymeric sheet. The apertured sheets may comprise filter media and/or support membranes for filter media in gas or liquid filters. The nanoparticles reduce the overall pressure drop across the support membranes to improve the efficiency of such filters.

Disclosed herein is a particulate filter for use in an emission treatment system of an internal combustion engine. The particulate filter provides high fresh filtration efficiency and has minimal to no impact on backpressures.

The present invention provides a particulate filter for use in an emission treatment system of a gasoline engine, the filter having an inlet side and an outlet side, wherein at least the inlet side is loaded with a synthetic ash.

An electrically regeneratable filter element comprises at least two flanks, each of these flanks comprising a stiff material layer. Each of these flanks has at least one thermally and electrically insulated side. The filter element comprises further a metal fiber fleece being pleated according to pleating lines providing an edge with pleat openings. The metal fiber fleece is mounted between the flanks, in such a way that the thermally and electrically insulated sides make contact with the edge, meanwhile these sides closing the pleat openings.
