  • Patent number: 7785384
    Abstract: A filter assembly is configured to be incorporated into an exhaust treatment device. The filter assembly comprises a frame, a filter media element, and a plurality of dividers supporting the filter media element within the frame. The frame has a first end and a second end defining a frame length therebetween. The filter media element is disposed within the frame and extends generally perpendicular to the frame length as a series of pleated contours. The plurality of dividers includes a first divider and a second divider. The first divider is disposed adjacent to the filter media element at the first end of the frame. The second divider is disposed adjacent to the filter media element at the second end of the frame.

  • Publication number: 20090100809
    Abstract: A filter assembly for removing particulates in an exhaust gas in a fuel engine is provided. The filter assembly comprises a primary filter having a first side and a second side, the primary filter configured to remove an amount of particulates from the exhaust gas flowing from the first side to second side; and a foam element disposed proximate to the first side of the primary filter, the foam element configured to remove another amount of particulates from the exhaust gas.

  • Publication number: 20080282682
    Abstract: An integrated DPF loading and failure sensor with two particulate matter sensors one located upstream of the filter and the other located downstream of the filter. The sensors are integrated into the leading and trailing edges of the filter. Integrating two particulate matter sensors with the DPF will allow the proper interval between reconditioning of DPF, since the particulate matter collected on the filter is measured and not estimated. The upstream sensor determines the amount of particulate matter entering the filter. In addition to using the first sensor for loading, the second sensor, at the trailing face of the filter, can be used to determine break-through of the DPF. The second sensor measures the particulate matter escaping the filter.

  • Publication number: 20080224343
    Abstract: A method of producing a porous ceramic media structure is provided. The method comprises preparing an aqueous solution that comprises ceramic fibers in a liquid carrier, adding a pore-forming, fibrous material to the aqueous solution, drying the aqueous solution to form a ceramic web, and removing the fibrous material from the ceramic web to thereby increase the porosity of the ceramic web.
