  • Exhaust gas aftertreatment module
    Patent number: 9556781
    Abstract: An aftertreatment module for the treatment of exhaust gasses from a power system includes a first aftertreatment brick and a second aftertreatment brick. The first and second aftertreatment bricks can be flow-through type catalysts for catalyzing byproducts in the exhaust gasses. The aftertreatment module can include a first channel directing the incoming exhaust gasses in a first direction through the first aftertreatment brick and a second channel directing the exhaust gasses through the second aftertreatment brick. The first and second channel can be in a side-by-side arrangement. To communicate the exhaust gasses between the first and second channels, a traverse channel can redirect the gas flow within the aftertreatment module.
