Abstract

An exhaust dispersion device for an exhaust system with an outer flow member is disclosed. The exhaust dispersion device includes a dispersion member capable of being disposed within the outer flow member. The dispersion member defines an axis and includes an upstream end and a downstream end. A cross section of the downstream end perpendicular to the axis is larger than a cross section of the upstream end perpendicular to the axis. The dispersion device also includes an aperture extending through the dispersion member. The aperture is coaxial with the axis. Flow of all exhaust gas through the outer flow member is divided between flow through the aperture and flow between the outer flow member and the dispersion member. The dispersion member is operable to divert the flow of the exhaust gas at least partially toward the outer flow member.
