Patent number: 8808418Abstract: A system for treating diesel exhaust is disclosed. The system includes a first filter including layers of filtration material positioned between layers of corrugated metallic foil. The metallic foil defines a honeycomb arrangement of longitudinal passageways from an upstream end to a downstream end and also openings for allowing exhaust to pass between adjacent longitudinal passageways of the metallic foil. The filtration material is positioned such that exhaust between the adjacent longitudinal passageways passes through the filtration material. The metallic foil also includes flow diverting structures to divert flow within the longitudinal passageways through the openings. A second filter is positioned downstream from the first filter. The second filter defines a honeycomb arrangement of longitudinal passageways. The longitudinal passages are selectively plugged adjacent upstream and downstream ends to force flow radially through walls between the longitudinal passages of the second filter.Type: GrantFiled: July 16, 2012Date of Patent: August 19, 2014Assignee: Donaldson CompanyInventors: Wenzhong Zhang, Todd R.

Patent number: 7607289Abstract: Methods, constructions, and systems for treating engine emissions. An engine includes a crankcase, an air intake, a blow-by vent, and an exhaust port; the crankcase emits blow-by gases through the blow-by vent, and the engine produces an exhaust stream through the exhaust port. The blow-by gases are directed through a blow-by filter to produce filtered gases. The filtered gases are directed back into the air intake of the engine; and the exhaust stream is treated with at least one of a catalytic converter, a flow through filter, and a diesel particulate filter. Total particulate matter (PM) emissions of a turbo-charged diesel engine having an engine crankcase and an exhaust tailpipe are reducible. The total emissions includes particulate matter emissions from the engine crankcase added to the particulate matter emissions from the exhaust tailpipe.Type: GrantFiled: October 8, 2007Date of Patent: October 27, 2009Assignee: Donaldson Company, Inc.Inventors: Steve D.

Patent number: 7340888Abstract: A diesel exhaust treatment system is disclosed that includes first and second diesel particulate reduction devices. The first diesel particulate reduction device is located upstream in the exhaust flow and contains an oxidation catalyst coating. The second particulate reduction device is located downstream from the first particulate reduction device and is generally non-catalyzed or lightly catalyzed. Each particulate reduction device comprises a flow-through fabric-type filtration media with substantial internal turbulence. As exhaust gas passes through the catalyzed upstream particulate reduction device, nitric oxide (NO) is oxidized to form nitrogen dioxide (NO2), a portion of which interacts with the particulate trapped within the upstream diesel particulate reduction device to regenerate the upstream device.Type: GrantFiled: March 10, 2006Date of Patent: March 11, 2008Assignee: Donaldson Company, Inc.Inventors: Wenzhong Zhang, Julian A.

Publication number: 20050247051Abstract: The present invention relates to an engine exhaust treatment system (20) including a first exhaust gas path (24) having a diesel particulate filter (32) and a second exhaust gas path (26) having a catalytic converter (34). The system also includes a valve arrangement (36, 38), for controlling exhaust gas flow between the first and second paths (24, 26). The system (20) further includes a controller (40) for sensing/monitoring operating conditions of the engine (22) and the condition of the diesel particulate filter (32). The controller (40) shifts exhaust gas flow between the first and second paths (24, 26) based on the operating condition of the engine (22) and/or the condition of the diesel particulate filter (32) to optimize filtration efficiency while preventing unacceptable levels of backpressure and detrimental regeneration of the filter (32).Type: ApplicationFiled: October 25, 2002Publication date: November 10, 2005Applicant: Donaldson Company, Inc.Inventors: Wayne Wagner, Edward Steinbrueck, Julian Imes

Patent number: 6508277Abstract: The present disclosure relates to a flexible pipe including a pipe body that extends along a central longitudinal axis. The pipe body is made from a strip that is helically wrapped in a plurality of convolutions. The strip includes inner and outer hook portions that interlock to form an interlock seam between adjacent convolutions. The pipe body includes a mid-portion positioned between first and second end portions. At least the first end portion has an axial length L1 that traverses at least several of the convolutions of the pipe body. The first end portion is crushed radially inward relative to the mid-portion such that the first end portion has an effective outer diameter D1 that is smaller than an effective outer diameter D2 of the mid-portion. A first transition region is positioned between the first end portion and the mid-portion. The first transition region provides a diameter transition between the outer diameter D1 of the first end portion and the outer diameter D2 of the mid-portion.Type: GrantFiled: July 27, 1999Date of Patent: January 21, 2003Assignee: Donaldson Company, Inc.Inventors: Julian A.

Patent number: 6305054Abstract: The present disclosure relates to a clamp for sealing a lap joint formed by a first pipe inserted within a second pipe. The clamp includes a strap having a concave inner curvature that curves about a central axis. The strap includes a first axial end positioned opposite from a second axial end. A first axial portion of the strap is positioned at the first axial end, and a second axial portion of the strap is positioned at the second axial end. The first axial portion has a cylindrical inner surface adapted to provide a seal about the first pipe, and the second axial portion has a cylindrical inner surface adapted to form a seal about the second pipe. A radial in-step connects the first and second axial portions. The radial in-step provides a diameter transition between an inner diameter D1 of the first axial portion and an inner diameter D2 of the second axial portion such that the inner diameter D1 is larger than the inner diameter D2.Type: GrantFiled: July 2, 1999Date of Patent: October 23, 2001Assignee: Donaldson Company, Inc.Inventors: Julian A.
