Exhaust gas mixer and system

摘要

A device and a system are provided. The system may include a perforated barrier disposed within an exhaust stream downstream from the combustion chamber(s). The barrier may divide the exhaust stream radially and longitudinally. A mixing surface may be coupled with the perforated barrier which may define a path within the exhaust stream to impart a swirl to the exhaust stream.

1. A system, comprising:
a perforated bell-shaped wall, where the bell-shaped wall is a continuous curved convex to concave surface, disposed within an exhaust stream downstream of an engine cylinder and dividing the exhaust stream radially and longitudinally; and a swirl-shaped mixing surface coupled with and extending radially outward from an outer surface of the bell-shaped wall, the mixing surface defining a path within the exhaust stream to impart a swirl to the exhaust stream.
