Abstract

An exhaust system includes an exhaust duct having an internal surface defining an exhaust gas passage extending along an axis. At least one sensor opening is in the exhaust duct and is configured to receive an exhaust gas sensor. A wall is positioned within the exhaust gas passage to extend at least partially around the at least one sensor opening. The wall has an inner wall surface defining an internal volume. A plurality of inlet pipes are in fluid communication with the internal volume, and each inlet pipe extends from a first end open to the internal volume to a second end that is distal from the first end. Each inlet pipe includes a plurality of inlet apertures.
