Abstract

An insulation system for an aftertreatment system includes a first insulating element including at least one slit, and a second insulating element including a plurality of fingers extending from opposing sides of an aperture. The second insulating element is couplable to the first insulating element, and when the second insulating element is coupled to the first insulating element, the plurality of fingers overlap the at least one slit.

First claim

What is claimed is:

1. An insulation system for an aftertreatment system, comprising:
a first insulating element including at least one slit; and
a second insulating element including a plurality of fingers extending from opposing sides of an aperture,
wherein the second insulating element is couplable to the first insulating element, and wherein, when the second insulating element is coupled to the first insulating element, the plurality of fingers overlap the at least one slit,
wherein each finger of the plurality of fingers includes a fixed end and a free end, wherein the fixed end of a first finger is positioned on a first side of the aperture, wherein the fixed end of a second finger is positioned on a second side of the aperture,
wherein the second insulating element includes at least one internal coupling positioned between the second finger and the aperture, wherein the free end of the first finger is configured to be coupled to the internal coupling, and
wherein the first finger includes at least one rear coupling, and wherein the free end of the second finger is configured to be coupled to the rear coupling.

2. The insulation system of claim 1 , wherein the at least one slit in the first insulating element extends in a first direction, and wherein the aperture in the second insulating element extends in the first direction.

3. The insulation system of claim 2 , wherein each finger of the plurality of fingers extends in a second direction, and wherein the second direction is perpendicular to the first direction.

4. The insulation system of claim 1 , wherein the plurality of fingers includes two groups of fingers positioned on opposing sides of the aperture, and wherein each group of fingers includes at least two fingers.

5. The insulation system of claim 4 , wherein the free end of each finger is configured to be coupled to the second insulating element on the other of the first or second side of the aperture.

6. The insulation system of claim 5 , wherein a first group of fingers includes at least two fingers with the fixed ends coupled to the first side of the aperture,
wherein a second group of fingers includes at least two fingers with the fixed ends coupled to the second side of the aperture .

7. The insulation system of claim 6 , wherein each finger of the second group includes a coupling element on the free end on an internal face, wherein the coupling element on the free end on the internal face of each finger of the first group is configured to be coupled to a coupling element on the second insulating element.

8. The insulation system of claim 1 , wherein the second insulating element includes a planar portion configured to overlap with a portion of the first insulating element and a rectangular portion configured to extend away from the planar portion and beyond the first insulating element.

9. The insulation system of claim 1 , wherein the first insulating element is a planar blanket, wherein the first insulating element includes a plurality of straps and hooks positioned on opposing ends of the planar blanket, and wherein the straps and hooks are configured to couple the first insulating element around a cylindrical intake or outlet element.

10. The insulation system of claim 1 , wherein the first insulating element and the second insulating element, including the plurality of fingers, are formed of a silicon coated fiberglass.

11. An insulation assembly for an aftertreatment system, comprising:
an intake spool;
a treatment module coupled to the intake spool;
an outlet spool extending from the treatment module;
a first insulation assembly coupled to the intake spool, including a first primary blanket and a first secondary blanket, wherein the first secondary blanket is coupled to the first primary blanket; and
a second insulation assembly coupled to the outlet spool, including a second primary blanket and a second secondary blanket, wherein the second primary blanket includes an aperture, and wherein the second secondary blanket is coupled to the second primary blanket,
wherein the second secondary blanket includes a plurality of secondary blanket fingers, wherein each finger of the plurality of secondary blanket fingers includes a fixed end and a free end, wherein the fixed end of a first secondary blanket finger is positioned on a first side of the aperture, wherein the fixed end of a second secondary blanket finger is positioned on a second side of the aperture,
wherein the second secondary blanket includes at least one internal coupling positioned between the second secondary blanket finger and the aperture, wherein the free end of the first secondary blanket finger is configured to be coupled to the internal coupling, and
wherein the first secondary blanket finger includes at least one rear coupling, and wherein the free end of the second secondary blanket finger is configured to be coupled to the rear coupling.

12. The insulation assembly of claim 11 , further including one or more sensors, wires, or cables extending from the intake spool, wherein the one or more sensors, wires, or cables extends through a first opening in the first primary blanket and through a second opening in the first secondary blanket.

13. The insulation assembly of claim 12 , wherein the first opening in the first primary blanket is a slit through the first primary blanket, wherein the slit extends in a first longitudinal direction, wherein the second opening in the first secondary blanket is an aperture, and wherein the aperture at least partially overlaps with the slit when the first secondary blanket is coupled to the first primary blanket.

14. The insulation assembly of claim 13 , wherein the first secondary blanket includes a plurality of fingers extending from opposing sides of the aperture, wherein each finger of the plurality of fingers extends in a second longitudinal direction, wherein the second longitudinal direction is perpendicular to the first longitudinal direction, and wherein the fingers are configured to surround a portion of the one or more sensors, wires, or cables extending from the intake spool.

15. The insulation assembly of claim 14 , wherein each finger of a first group of fingers includes a coupling element on a first face of a free end, wherein the coupling element on the first face of the free end of each finger of the first group is configured to be coupled to a coupling element on the first secondary blanket on an opposite side of the aperture, and wherein each finger of the first group includes a coupling element on a second face of a fixed end, and wherein each finger of a second group of fingers includes a coupling element on a first face of a free end, with the coupling element on the first face of the free end of the fingers of the second group is configured to be coupled to the coupling element on the second face of the fixed end of one finger of the first group.

16. An insulation system for an aftertreatment system, comprising:
a first insulating element including at least one slit; and
a second insulating element including a plurality of fingers extending from opposing sides of an aperture,
wherein the second insulating element is couplable to the first insulating element, and wherein, when the second insulating element is coupled to the first insulating element, the plurality of fingers overlap the at least one slit, and
wherein the second insulating element includes one or more internal couplings, wherein a first finger is couplable to one of the one or more internal couplings, and wherein a second finger on an opposite side of the aperture from the
