Abstract: An aftertreatment system comprises a housing including a housing mounting surface and a mounting aperture defined therein. A frame has a frame first surface, a frame second surface opposite the frame first surface and defines a frame throughhole therethrough. The housing mounting surface is in contact with the frame first surface such that the frame throughhole is axially aligned with the mounting aperture. A biasing member includes a biasing member proximal end contacting the frame second surface proximate to the frame throughhole. A sleeve has a sleeve proximal end which is inserted through the frame throughhole. A sleeve distal end first surface of the sleeve is in contact with a biasing member distal end. A fastener including a fastener proximal end is inserted through the sleeve channel into the mounting aperture and removably coupled to the mounting aperture so that the biasing member is at least partially compressed.

Abstract: An aftertreatment system comprises a housing having an inlet, an outlet and a sidewall. The housing defines an internal volume structured to receive an exhaust gas via the inlet. The sidewall defines an access opening. An access panel is operatively coupled to the sidewall and covers the access opening. The access panel defines a plurality of throughholes. Each of the plurality of throughholes are configured to receive a fastener therethrough for removably coupling the access panel to the sidewall. An injection port is also defined in the access panel. An injector is positioned on the access panel. The injector is removably coupled to the access panel via a coupling assembly so that the injector is in fluidic communication with the internal volume via the injection port. A SCR system is disposed in the internal volume and includes at least one catalyst formulated to decompose constituents of the exhaust gas.
