  • Publication number: 20070158941
    Abstract: A joint is provided permitting relative radial and axial movement between a first wall thermally expanding at a first amount and a second wall thermally expanding at a second amount. The joint includes a first fixed connection between a first edge of the second wall and the first wall. The joint also includes an endplate including a first edge and a second fixed connection between a second edge of the second wall and the first edge of the endplate. The joint also includes a clip and a third fixed connection between the clip and the first wall. The joint further includes a fourth fixed connection between the clip and the endplate, the clip permitting the relative radial and axial movement.

  • Publication number: 20060191412
    Abstract: An on-vehicle service system for removing matter from a filtering device of a single filtering device exhaust system includes a controllable filter bypass line fluidly connecting a first orifice of the filtering device of the single filtering device exhaust system to a second orifice of the filtering device. The service system also includes a receptacle fluidly connected to the filtering device and configured to collect at least a portion of the matter removed by the on-vehicle service system when a fluid is provided through a portion of the filter bypass line into the filtering device.

  • Publication number: 20060144223
    Abstract: According to an exemplary embodiment of the present disclosure, a method of loading a filtering device includes measuring a metric indicative of an initial loading of the filtering device and desirably positioning a quantity of matter proximate the filtering device. The method also includes applying a negative pressure to the filtering device such that at least a portion of the quantity of matter is drawn into the filtering device. The method further includes measuring a metric indicative of a final loading of the filtering device.
