Abstract: Systems and methods for an aftertreatment system configured for use with a dual-fuel engine system are described. The method comprises determining an operating mode of the dual-fuel engine. Upon determining that the dual-fuel engine is operating in a dual-fuel mode or a natural gas mode, the dual-fuel engine operates in a stoichiometric operating condition, and the exhaust is received into a three-way catalyst communicatively connected to a selective catalytic reduction catalyst. Upon determining that the dual-fuel engine is not operating in the dual-fuel mode or the natural gas mode, the engine operates in a lean operating condition.

Abstract: An aftertreatment component for use in an exhaust aftertreatment system. The aftertreatment component comprises an aftertreatment substrate and a compressible material. The compressible material may be formed from a plastic thermoset, a rubberized material, or a metal foil which permits for the selective expansion of the substrate within the compressible material, while also reducing cost and manufacturing complexity. In various embodiments, the aftertreatment substrate and the compressible materials may be formed separately and coupled to each other, or they may be formed concurrently via coextrusion.
