Abstract

A doser mounting bracket for coupling a doser to an exhaust gas aftertreatment system component having a sidewall and an exhaust gas aftertreatment system component opening includes a lower surface, an engagement wall, a central structure, an upper surface, and an attachment structure. The lower surface is configured to be held in a position opposing the sidewall. The engagement wall extends from the lower surface. The central structure has an opening that extends therethrough and includes a centering structure that extends from the lower surface and is configured to be received within the exhaust gas aftertreatment system component opening. The attachment structure extends from the upper surface and is configured to be coupled to the doser. The engagement wall is configured to separate the lower surface from the sidewall when the engagement wall interfaces with the sidewall such that a pocket is formed between the engagement wall, the centering structure, and the lower surface.
