Engine Exhaust Aftertreatment Component Including Aftertreatment Brick Module

An aftertreatment brick module for an engine exhaust aftertreatment component, the engine exhaust aftertreatment component including a housing defining an exhaust flow path from an exhaust inlet to an exhaust outlet, wherein the housing supports a plurality of internal support channels, the aftertreatment brick module comprising:

• a catalytic brick having an upstream face and a downstream face;
• a can defining a chamber extending from an open upstream end to an open downstream end, wherein the catalytic brick is positioned within the chamber;
• an upstream end plate disposed along the upstream end and including an upstream opening therethrough corresponding to the upstream face;
• and
• a downstream end plate disposed along the downstream end and including a downstream opening therethrough corresponding with the downstream face;
• wherein each of the upstream end plate and the downstream end plate includes a first coupling mechanism positioned along a first opposing side of a respective one of the upstream end plate and the downstream end plate, and a second coupling mechanism positioned along a second opposing side of the respective one of the upstream end plate and the downstream end plate;
• wherein each of the first coupling mechanism and the second coupling mechanism of each of the upstream end plate and the downstream end plate is configured to be received within a separate one of the plurality of internal support channels.

A method of treating exhaust from an internal combustion engine using an aftertreatment brick module, the aftertreatment brick module including a catalytic brick, a can configured to receive the catalytic brick, and an end plate disposed along an end of the can, wherein the end plate includes a coupling mechanism, the method comprising:

• slidably moving the aftertreatment brick module into a housing of an engine exhaust aftertreatment component along a slide path by receiving the coupling mechanism within an internal support channel of the housing;
• directing exhaust from an exhaust inlet defined by the housing toward the aftertreatment brick module along an exhaust flow path;
• and
• directing exhaust from the aftertreatment brick module toward an exhaust outlet defined by the housing along the exhaust flow path, wherein the exhaust flow path is substantially transverse to the slide path.
