Appl. No.:

11/094526

Inventors:

Leonel Arellano - Poway CA, US
Vu Phi - San Diego CA, US

Kenneth Smith - San Diego CA, US

International Classification:

F01N 3/00

US Classification:

060295000, 060297000

Abstract:

An exhaust treatment system is provided. The system may include a particulate trap configured to remove one or more types of particulate matter from an exhaust flow, the exhaust flow including at least a portion of a totality of exhaust gases produced by an engine. The system may further include a burner assembly configured to increase a temperature of gases in the exhaust flow at a location upstream from the particulate trap. The burner assembly may include an exhaust inlet oriented in a direction along a first axis and configured to direct the exhaust flow into the burner assembly and an exhaust outlet oriented in a direction along a second axis at an angle relative to the first axis, the exhaust outlet being configured to direct the exhaust flow out of the burner assembly toward the particulate trap. The burner assembly may also include a fuel injector having a longitudinal axis in substantial alignment with the second axis. In addition, the burner assembly may include a cylindrical combustion chamber member defining a combustion chamber, having a longitudinal axis in substantial alignment with the longitudinal axis of the fuel injector, and configured to house a flame that is fueled by the fuel injector within the combustion chamber. The burner assembly may further include an exhaust flow distribution member configured to substantially evenly distribute exhaust about the combustion chamber member and in a heat exchange relation to the combustion chamber member.

Abstract:

A combustor liner may include an annular inner liner and an annular outer liner with a plurality of air holes thereon. The outer liner may be positioned circumferentially around the inner liner such that an annular cooling space is defined between the inner and the outer liner. The combustor liner may also include at least one resonator coupled to the outer liner such that a base of the resonator is separated from the outer liner to form a gap with an external surface of the outer liner. The combustor liner may also include a throat extending from the base of the resonator penetrating the inner liner and the outer liner. The combustor liner may further include a grommet assembly that allows for relative thermal expansion between the inner liner and the outer liner proximate the throat.
