A removable exhaust treatment unit for an aftertreatment assembly, comprising:
- a housing;
- at least one exhaust treatment element coupled within the housing;
- a flange on one end of the housing;
- a plurality of apertures on the flange configured to receive a plurality of fasteners;
- and
- at least one handle coupled to the flange, the at least one handle extending inward from a perimeter of the flange and overlapping a portion of the at least one exhaust treatment element wherein the exhaust treatment unit is removable from an enclosure, and the flange is disposed within the enclosure and coupled to an inner support portion of the enclosure.
An engine system, comprising:
- an internal combustion engine configured to combust air and fuel to produce exhaust gases;
- a first exhaust conduit;
- a second exhaust conduit;
- and
- an emissions control filter assembly, including:
- an enclosure defining an interior and including an inlet, an outlet, and an opening, wherein
- the inlet is connected with the first exhaust conduit and configured to receive a flow of exhaust gases from the first exhaust conduit;
- the outlet is connected with the second exhaust conduit and configured to direct the flow of exhaust gases to the second exhaust conduit;
- and
- the opening is configured to provide access to the interior;
- a cover portion spaced from the outlet and removably coupled with the enclosure, and configured to cover the opening and prevent the flow of exhaust gases from flowing through the opening;
- and
- a removable exhaust treatment unit disposed within the interior of the enclosure and removably coupled with the enclosure, the removable exhaust treatment unit configured to contain at least one exhaust treatment element and to be removable through the opening when the cover portion is removed, wherein the outlet is included in a wall forming an outer perimeter of the enclosure, the outlet disposed between the cover portion and the exhaust treatment element.
An emissions control filter assembly, comprising:
- an enclosure defining an interior and including an inlet, an outlet, and an opening configured to provide access to the interior;
- a cover portion removably coupled with the enclosure and configured to cover the opening;
- and
- a removable exhaust treatment unit disposed within the interior of the enclosure and removably coupled with the enclosure, the removable exhaust treatment unit including:
- a housing;
- at least one exhaust treatment element coupled within the housing;
- a flange on one end of the housing and disposed within the interior of the enclosure;
- a plurality of apertures on the flange configured to receive a plurality of fasteners;
- and
- at least one handle coupled to the flange.
A method of providing an emissions control filter assembly, comprising:
- providing a removable exhaust treatment unit;
- securing an exhaust treatment element to the removable exhaust treatment unit;
- providing an enclosure;
- removably coupling a flange of the removable exhaust treatment unit with an annular support portion protruding inwardly from an interior surface of the enclosure, wherein removing the exhaust treatment unit from the enclosure comprises moving the flange across an exhaust outlet of the enclosure;
- providing an opening in the enclosure to give access to the removable exhaust treatment unit;
- and
- providing a removable cover portion for the opening.
