Patent Images
1. A catalyst assembly configured to mount along an exhaust flow path of a reciprocating combustion engine, comprising:
- a housing having an inlet portion, an outlet portion, a central portion disposed between the inlet portion and the outlet portion and configured to house one or more catalyst elements, and a flow path through the inlet portion, the central portion, and the outlet portion, wherein the outlet portion has a first end and a second end, the first end being coupled to the central portion, and the outlet portion comprises a first annular wall having a first diameter that decreases from the first end to the second end;
a cylindrical portion coupled to and extending from the second end of the outlet; and
at least one oxygen sensor connection disposed on the cylindrical portion to enable an oxygen sensor coupled to the at least one oxygen sensor connection to be disposed perpendicular to a longitudinal axis of the cylindrical portion.

Abstract
A system includes a cylindrical portion coupled to a conically-shaped outlet portion of a three-way catalyst assembly. The cylindrical portion is coupled to the conically shaped outlet portion along a fluid flow path exiting the conically-shaped outlet portion. The cylindrical portion is coupled to a narrower end of the conically-shaped outlet portion. At least one oxygen sensor connection is disposed on the cylindrical portion to enable an oxygen sensor coupled to the at least one oxygen sensor connection to be disposed perpendicular to a longitudinal axis of the cylindrical portion.
