    Abstract: A burner for an exhaust gas treatment system includes a tubular inner housing having a closed upstream end, a reduced diameter portion, and a plurality of apertures downstream of the reduced diameter portion. An outer housing surrounds the inner housing comprising a bypass flow path therebetween. First and second tubular supports fix the upstream end of the inner housing to the outer housing and provide fluid communication between a cavity within the inner housing to a location outside of the outer housing. A plate fixes the downstream end of the inner housing to the outer housing and cooperates with the housings to partially define an aperture formed in a portion of the bypass flow path.

    Abstract: An exhaust treatment system includes an exhaust treatment device. The exhaust treatment device includes a shell, and a sensor boss configured to support a sensor device is mounted to the shell. A Pitot tube that is configured to communicate exhaust to the sensor device is coupled to the sensor boss at a proximate end thereof, while a distal end is affixed to the shell of the exhaust treatment device to prevent detachment of the Pitot tube from the sensor boss, and ensure that exhaust gases are effectively communicated to the sensor device.

    Abstract: A muffler assembly for an exhaust system is in fluid communication with a collector via an exhaust conduit. The muffler assembly includes a primary pipe, a valve, a secondary pipe, a tuner tube and a bleed port. The primary pipe extends through an enclosed volume of the muffler. The valve is operable to restrict flow through the primary pipe. When a standing wave is present, a resonance length is defined by a length of the exhaust system that extends from the collector to the valve. The tuner tube includes an open tuner tube end in fluid communication with the primary pipe and a closed tuner tube end. The tuner tube has a tuner tube length that is substantially one-quarter of the resonance length. The bleed port is formed in the primary pipe, allowing fluid communication with the enclosed volume, and positioned downstream from open tuner tube end.

    Abstract: A vehicle exhaust system includes a tubular component defining a primary exhaust gas flow path with a primary exhaust gas outlet. At least one opening is defined by the tubular component and extends through an inner surface and an outer surface of the tubular component. A plate is disposed on the outer surface of tubular component and covers the at least one opening. A secondary exhaust gas flow path is defined by the at least one opening in the tubular component, through a plurality of elongated flow channels, and through the outlet opening defined by the plate. The exhaust gases flowing through the secondary exhaust gas flow path are exhausted to atmosphere in a different location than the primary outlet.

    Abstract: A vehicle exhaust system includes a tubular component defining a primary exhaust gas flow path. At least one opening defined by the tubular component extends through an inner surface and an outer surface of the tubular component. A patch covers the at least one opening. The patch includes a plate disposed on the tubular component. The plate defines at least one flow channel to receive exhaust gases from the at least one opening and impart at least one directional change to the received exhaust gases. The plate further defines at least one outlet opening adapted to receive exhaust gases from the flow channel. A secondary exhaust gas flow path is defined through the at least one opening in the tubular component, the flow channel defined by the plate, and the outlet opening defined by the plate.

    Abstract: A muffler includes a first tube defining a first inlet for receiving exhaust and a first outlet. The muffler includes a housing defining a tuning chamber. The muffler includes a second tube at least partially received within the first tube. Further, the second tube defines a second inlet disposed within the first tube and a second outlet disposed in fluid communication with the tuning chamber. The muffler further includes a muffler outlet for discharging exhaust from the muffler. Moreover, the first tube and the second tube define an annular passage therebetween. The annular passage is disposed in fluid communication with the first outlet of the first tube and the muffler outlet.
