Aftertreatment component cartridge for an aftertreatment system

An aftertreatment system comprising:

• an inlet conduit assembly comprising an inlet body that receives an exhaust gas, the inlet body comprising an inlet body wall portion and an inlet coupling flange portion that is flared outwardly from the inlet body wall portion;
• an outlet conduit assembly that is downstream of the inlet conduit assembly and comprises an outlet body, the outlet body comprising an outlet body wall portion and an outlet coupling flange portion that is flared outwardly from the outlet body wall portion;
• an aftertreatment component cartridge comprising:
• an aftertreatment component housing comprising:
• an inlet portion inserted in the inlet body,
• an outlet portion inserted in the outlet body;
• an adaptor comprising:
• a first coupling wall portion having an inner surface coupled to an outer surface of the aftertreatment component housing and disposed between the inlet coupling flange portion and the aftertreatment component housing,
• a second coupling wall portion having an inner surface coupled to the outer surface of the aftertreatment component housing and disposed between the outlet coupling flange portion and the aftertreatment component housing,
• a coupler portion contiguous with the first coupling wall portion and the second coupling wall portion, the coupler portion extending between the inlet coupling flange portion and the outlet coupling flange portion;
• and
• an aftertreatment system component positioned within the aftertreatment component housing.

An aftertreatment component cartridge for an aftertreatment system, the aftertreatment component cartridge comprising:

• an aftertreatment component housing;
• an adaptor comprising:
• a first flange portion having an inner surface coupled to an outer surface of the aftertreatment component housing,
• a first connecting wall portion contiguous with the first flange portion, a portion of the first connecting wall portion extending along a first slope from the first flange portion, the first slope having a first angle along a reference plane bisecting the adaptor,
• a first coupling wall portion contiguous with the first connecting wall portion, a portion of the first coupling wall portion extending along a second slope from the first connecting wall portion, the second slope having a second angle along the reference plane, the second angle greater than the first angle,
• a second flange portion having an inner surface coupled to the outer surface of the aftertreatment component housing,
• a second connecting wall portion contiguous with the second flange portion, a portion of the second connecting wall portion extending along a third slope from the second flange portion, the third slope having a third angle along the reference plane,
• a second coupling wall portion contiguous with the second connecting wall portion, a portion of the second coupling wall portion extending along a fourth slope from the second connecting wall portion, the fourth slope having a fourth angle along the reference plane, the fourth angle less than the third angle, and
• a coupler portion contiguous with the first coupling wall portion and the second coupling wall portion;
• and
• an aftertreatment system component positioned within the aftertreatment component housing.

A method for installing an aftertreatment component cartridge in an aftertreatment system having an inlet conduit assembly, an outlet conduit assembly, and a clamp, the inlet conduit assembly including an inlet body with an inlet body wall portion and an inlet coupling flange portion, the outlet conduit assembly including an outlet body with an outlet body wall portion and an outlet coupling flange portion, the aftertreatment component cartridge including an aftertreatment component housing with an inlet portion and an outlet portion, and an adaptor with a first flange portion coupled to the aftertreatment component housing, a second flange portion coupled to the aftertreatment component housing, a first coupling wall portion contiguous with the first flange portion and having a portion that extends along a first slope from the first flange portion, and a second coupling wall portion contiguous with the second flange portion and having a portion that extends along a second slope from the second flange portion, and the clamp including a first clamp flange portion and a second clamp flange portion, the method comprising:

• inserting the inlet portion into the inlet body such that the first flange portion is disposed between the aftertreatment component housing and the inlet body wall portion;
• inserting the outlet portion into the outlet body such that the second flange portion is disposed between the aftertreatment component housing and the outlet body wall portion;
• bringing into confronting relation, after inserting the inlet portion into the inlet body and the outlet portion into the outlet body, the first coupling wall portion and the inlet coupling flange portion;
• and
• bringing into confronting relation, after inserting the inlet portion into the inlet body and the outlet portion into the outlet body, the second coupling wall portion and the outlet coupling flange portion.
