Patent number: 11384669Abstract: 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.Type: GrantFiled: July 12, 2019Date of Patent: July 12, 2022Assignee: Caterpillar Inc.Inventors: Govind Swaroop, Raghuram Gaikwad, Scott Frederick Meyer, Bogdan Balea, Shawn Richard Herold

Patent number: 10132222Abstract: A component of the exhaust aftertreatment system includes a metallic body having a tapered portion. The component of the exhaust aftertreatment system further includes a curved plate arranged within the tapered portion of the metallic body. The curved plate has a plurality of perforations disposed on the curved plate to facilitate distribution of an exhaust mixture flowing through the curved plate across a surface of a substrate.Type: GrantFiled: December 5, 2016Date of Patent: November 20, 2018Assignee: Caterpillar Inc.Inventors: Bogdan Balea, Eric P. Spaeth

Patent number: 10066535Abstract: 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.Type: GrantFiled: November 17, 2016Date of Patent: September 4, 2018Assignee: Caterpillar Inc.Inventors: Yong Yi, Bogdan Balea, Eric Paul Spaeth
