Systems and methods for reductant delivery in aftertreatment systems for internal combustion engines
Patent number: 10837339Abstract: A dosing lance assembly for an exhaust component includes a housing and a delivery conduit. The housing includes a plate, an endcap, and a pipe. The plate has a first channel. The endcap has a second channel. The pipe has a first end coupled to the plate and a second end coupled to the endcap. The delivery conduit has a first end coupled to the plate and a second end coupled to the endcap, such that reductant is flowable from the first channel to the second channel. When the housing is at an ambient temperature, (i) a length of the delivery conduit is greater than (ii) a first distance between a location at which the first end of the pipe is coupled to the plate and a location at which the second end of the pipe is coupled to the endcap.Type: GrantFiled: September 27, 2018Date of Patent: November 17, 2020Assignee: Cummins Emission Solutions Inc.Inventors: Snehal Shivaji Yesumali, Colin L. Norris, Ronald Hale, Ken Hummel, Tyler Kent Lorenz, Raghunath Thakar -
Patent number: 10697342Abstract: An aftertreatment system includes: a selective catalytic reduction system including at least one catalyst for decomposing constituents of an exhaust gas produced by an engine, the exhaust gas having a pressure pulsation frequency; an exhaust conduit fluidly coupled to the selective catalytic reduction system and structured to deliver the exhaust gas to the selective catalytic reduction system from the engine; at least one mixer positioned in the exhaust conduit; and a reductant insertion assembly fluidly coupled to the exhaust conduit and structured to insert a reductant into the exhaust conduit upstream of the at least one mixer. The at least one mixer is structured to have a natural frequency matching the pressure pulsation frequency so as to cause resonant vibration in the at least one mixer, the resonant vibration causing reductant deposits to be removed from the at least one mixer.Type: GrantFiled: October 23, 2018Date of Patent: June 30, 2020Assignee: Cummins Emission Solutions Inc.Inventors: Atul S. Abhyankar, Ronald Hale

Patent number: 7350600Abstract: An earth-boring bit has a bit body that includes head sections, each having depending bit legs with a circumferentially extending outer surface, a leading side, and a trailing side. A bearing shaft depends inwardly from each of the bit legs for mounting a cutter. The bit includes a beveled surface formed at a junction of the leading side and the outer surface of each bit leg. The beveled surface is angled relative to a radial plane emenating from the axis of the bit. The angle of the beveled surface is at least 20 degrees, and extends to an inner surface of the bit leg. The bit can also have a layer of hardfacing on the leading, trailing and shirttail surfaces of the bit leg. A diversion finger of hardfacing extends circumferentially to direct cuttings.Type: GrantFiled: August 28, 2006Date of Patent: April 1, 2008Assignee: Baker Hughes IncorporatedInventors: Christopher C. Beuershausen, Raul E. Lema, Ronald Hales, Don Q. Nguyen, Gregory L. Ricks, Chih C. Lin, Terry J. Koltermann, Mark E. Morris, Chris M. McCarty, Ronald L. Jones, James L.
