Implementations described herein relate to features for an integrated aftertreatment system. In one implementation, an integrated aftertreatment system comprises a casing that includes a mating flange having a first constant diameter and a catalyst component configured to mate to the mating flange of the casing. The catalyst component includes a canned body including a first portion sized to a second constant diameter to mate with the first constant diameter of the mating flange. In another implementation, an integrated aftertreatment system comprises a casing, a catalyst component positioned within the casing, a particulate filter having an outer casing with an outlet, and a particulate filter joint coupled to the outer casing of the particulate filter at the outlet. An end of the particulate filter joint is aligned with an end of the particulate filter.

Integrated aftertreatment system

An aftertreatment system can include a radiation shield for reducing and/or redirecting radiative thermal energy. The aftertreatment system can include a first housing, a second housing, a first aftertreatment component, and the radiation shield. The first aftertreatment component is positioned within one of a first interior volume of the first housing or a second interior volume of the second housing. The radiation shield includes an attachment portion and a thermal barrier portion. The attachment portion is coupled to an exterior of the first housing or the second housing. The thermal barrier portion is structured to divert radiative thermal energy in a second direction different than a source direction of the radiative thermal energy.

V-band radiation heat shield

An aftertreatment system comprises a SCR system. The SCR system includes a housing having an inlet, an outlet and defining an internal volume. At least one catalyst can be positioned within the internal volume. A mounting support is positioned around at least a portion of a perimeter of the housing. A heat shield is positioned around the perimeter of the housing such that the housing is positioned substantially within the heat shield. A portion of the heat shield is disposed on and in contact with the mounting support. A clamp is positioned around a heat shield perimeter. The clamp is positioned on the portion of the heat shield disposed on and in contact with the mounting support. The mounting support is configured to transmit a clamping force of the clamp on the heat shield to the housing to prevent buckling of the heat shield from the clamping force.
