  • Patent number: 11248507
    Abstract: An apparatus comprises a housing including a housing first portion having a first joint portion configured to overlap a second joint portion of a housing second portion so as to form a housing joint. A primary clamp is positioned at a primary location of the housing joint which abuts at least a portion of the first and the second joint portion. A mounting bracket is positioned on and contacts the primary clamp. A plurality of secondary clamps are positioned at secondary locations, each of which is different than the primary location, of the housing joint. A band is operatively coupled to the mounting bracket by positioning around and contacting each of the plurality of secondary clamps. The band is tightened to urge the mounting bracket and thereby the primary clamp, and the plurality of secondary clamps towards the housing joint to secure the housing joint.

  • Patent number: 11208927
    Abstract: An aftertreatment component includes an inlet connector tube, an outlet connector tube, a chamber, a flow dissipater, and a substrate. The inlet connector tube receives exhaust gasses. The chamber is between the inlet connector tube and the outlet connector tube. The flow dissipater is positioned around the inlet connector tube and within the chamber. The flow dissipater receives the exhaust gasses from the inlet connector tube and includes a plurality of perforations. The plurality of perforations defines an open area of the flow dissipater. The open area of the flow dissipater is greatest proximate to the inlet connector tube and progressively decreasing proximate to the outlet connector tube. The substrate is positioned within the chamber and receives the exhaust gasses from the flow dissipater and provides the treated exhaust gasses to the outlet connector tube. The exhaust gases are expelled through the flow dissipater via the plurality of perforations.
