Abstract

An emission abatement assembly (14) includes a housing (62) having an inlet (38) and an outlet (69), the inlet (38) being configured to receive exhaust gas from an exhaust manifold (15) of an internal combustion engine (13). The assembly (14) further includes a fuel-fired burner (18) disposed within the housing (62) and a particulate filter (20) positioned downstream of the fuel-fired burner (18). The assembly (14) further includes a baffle assembly (24) positioned downstream of the particulate filter (20). The baffle assembly (24) includes a cap (28) configured to redirect exhaust gases exiting the outlet (69) in a downwardly and outwardly direction and a first baffle (30) configured to redirect exhaust gases redirected by the cap (28) in an upwardly and outwardly direction. A method of operating an emissions abatement assembly (14) is also disclosed.
