Patent number: 8535612Abstract: Disclosed is a diesel particle filter with a ceramic filter body and a method for producing the filter body. The ceramic filter body includes gas channels provided in a filter section with planar and porous filter walls. The filter walls provide throughflow of the exhaust gas flow perpendicular to the surfaces thereof. The filter body includes at least one catalytic section for catalytic purification of the exhaust gas flow. The filter body together with the filter section and the at least one ceramic section are made in one-piece from at least one ceramic impregnated fiber web. Gas channels are formed by sintering the fiber web at a temperature such that fibers of the fiber material are burned away and the ceramic material is monolithically sinter-bonded in one-piece with the at least one catalytic section and the filter section to produce the filter body.Type: GrantFiled: March 3, 2008Date of Patent: September 17, 2013Assignee: Mann + Hummel GmbHInventors: Michael Micke, Sabine Otterbach

Patent number: 8518143Abstract: The invention relates to a method for producing a ceramic filter element in an exhaust gas filter for an internal combustion engine, in particular a diesel particulate filter, wherein a base paper carrier web is soaked with a ceramic slip and then burnt out. The base paper carrier web uses a thickness and/or structure that varies over the width and/or length of the base paper carrier web.Type: GrantFiled: August 10, 2011Date of Patent: August 27, 2013Assignee: Mann+Hummel GmbHInventors: Jochen Linhart, Sabine Otterbach, Kathrin Lichtenwalter

Publication number: 20120001371Abstract: The invention relates to a method for producing a ceramic filter element in an exhaust gas filter for internal combustion engines, wherein a wound paper element that comprises flow channels on one or both sides that are sealed on alternating sides with a ceramic plugging is formed, soaked with a ceramic slip, and then dried and sintered. The ceramic plugging is applied with an inward offset from the end face of the wound paper element.Type: ApplicationFiled: August 9, 2011Publication date: January 5, 2012Applicant: MANN+HUMMEL GMBHInventors: Jochen Linhart, Sabine Otterbach, Kathrin Lichtenwalter, Kathrin Fischer

Patent number: 8038928Abstract: In a method for manufacturing a ceramic filter element for an exhaust gas filter for internal combustion engines, a combustible non-ceramic support web provided with flow channel is impregnated with ceramic slurry. Subsequently, the support web, formed in a desired geometric shape, is fired until the support web is combusted and a rigid filter body is produced. Before impregnating the support web, a combustible sealing bead is applied such onto the support web that the flow channels are closed alternatingly by the sealing bead.Type: GrantFiled: December 17, 2008Date of Patent: October 18, 2011Assignee: Mann + Hummel GmbHInventor: Sabine Otterbach

Publication number: 20100180560Abstract: The invention concerns a device for aftertreatment of a hot exhaust gas flow (2), in particular of a diesel engine, comprising a ceramic filter body (1) of a ceramic material (6) with gas passages (18, 18?). The filter body (1) is formed unitarily of at least one fiber web (4, 4?), in particular paper, impregnated with the ceramic material (6) with formation of the gas passages (18, 18?) and configured with heat exposure by sintering such that fibers of the fiber web (4, 4?) are burnt off and in that the ceramic material (6) is sintered together as a unitary monolithic part to form the filter body (1). At least two ceramic filter bodies (1) are provided that are separately embodied from one another and connected fluidically parallel to one another. Each filter body (1) is limited with regard to its size such that it withstands the thermal loads of the hot exhaust gas flow (2).Type: ApplicationFiled: March 7, 2008Publication date: July 22, 2010Applicant: MANN+HUMMEL GMBHInventors: Michael Micke, Karin Gerlach, Jochen Linhart, Kathrin Lichtenwalter, Sabine Otterbach, Holger Findeisen
