    Abstract: A reductant storage system for an internal combustion engine system includes a storage container having a bottom wall, a top wall opposite the bottom wall, an opening extending through the top wall, and a reservoir formed by a hollow interior of the storage container and a filter assembly. The filter assembly extends through the opening and include a filtering material and a gasket integrally formed with the filtering material. The gasket includes a proximal flange that is larger than the opening and including a sealing surface in sealing contact with the storage container.

    Abstract: A base filter for a diesel exhaust fluid (DEF) filter of a header assembly in a fluid reservoir is disclosed may include first and second semi-cylindrical holder portions having a semi-cylindrical walls concluding at abutment surfaces that face and engage when the base filter is assembled. The semi-cylindrical holder portions have one or more mounting tabs extending inward from inner surfaces of the semi-cylindrical walls. The header assembly may include a header with a cylindrical header boss having mounting recess defined therein. The mounting tabs may be circumferentially spaced about the semi-cylindrical walls to align with and be inserted into the mounting recesses of the header boss the base filter is assembled on the cylindrical header boss. Fasteners may be inserted through fastener bosses of the semi-cylindrical holder portions and into fastener bores of the header boss to hold the semi-cylindrical holder portions together and on the header.

    Abstract: An exhaust aftertreatment system includes a housing including at least one exhaust aftertreatment component. The housing defines a body portion and an outlet portion terminating in an outlet opening. The outlet portion decreases in diameter from the body portion toward the outlet opening. A sampling tube is positioned within the outlet portion and extends between opposing sides of an inner wall of the outlet portion, with the sampling tube having a plurality of openings facing the body portion. A NOx sensor is positioned in fluid communication with an interior of the sampling tube.
