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.

Patent number: 9878610Abstract: A strap adjustment mechanism may include a pin with a pin opening that is insertable into a looped portion of an end of a strap. The strap adjustment mechanism may also include a fastener support assembly that has a first member and a second member. The second member is configured to translate along a central axis relative to the first member in response to rotation of the first member. The first member includes a first opening substantially collinear with the central axis of the second member, and the second member includes a second opening substantially collinear with the central axis of the second member. The strap adjustment mechanism further includes a strap attachment member that is insertable through the first and second openings of the first member and the second member. The strap attachment member is configured to engagably couple to the pin via the pin opening.Type: GrantFiled: May 4, 2017Date of Patent: January 30, 2018Assignee: Cummins Emission Solutions, Inc.Inventors: Ken Hummel, Raghunath Thakar, Scott Ehlenfeldt
