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 vehicle exhaust system and method of minimizing a leaked mass flow comprising an exhaust component defining a central axis and having an inner surface and an outer surface, such that the inner surface defines a primary exhaust gas flow path extending along the central axis from an inlet to an outlet, and a surface component having a hood spaced from the exhaust component to define a reservoir having a reservoir volume (V), the reservoir comprising a reservoir inlet fluidly coupled to the primary exhaust gas flow path and defining an inlet area (A), and a reservoir outlet fluidly coupled to an outside environment. The reservoir volume and inlet area having a defined relationship. The reservoir volume and a mass flow through the inlet area having a defined relationship.

Abstract: A vehicle exhaust system for allowing passage of exhaust gasses therethrough. The vehicle exhaust system has a first pipe having a first end and a second end. The first end defines an exhaust gas inlet and the second end defines an exhaust gas outlet. The vehicle exhaust system also has a second pipe positioned downstream of the first pipe and has a third end and a fourth end. At least a portion of the second end of first pipe is positioned within the third end of the second pipe defining an overlap between the second end of the first pipe and the third end of the second pipe. The first pipe and the second pipe together define a volume for the exhaust gasses. The volume comprises a first volume passageway between the exhaust gas inlet and the exhaust gas outlet and a second volume passageway defined by the overlap of the second pipe and the first pipe and having an inlet for exhaust gasses into the second volume passageway and an outlet from the second volume passageway positioned axially upstream of inlet. The inlet is positioned downstream of the exhaust gas outlet

Abstract: A muffler may include a shell, first and second baffles, an inlet pipe, first and second outlet pipes, and a communication pipe. The first and second baffles cooperate with the shell to define first, second and third chambers. The first inlet pipe may extend through the shell and may provide exhaust gas to at least one of the first and second chambers. Exhaust gas in the first chamber exits the muffler through the first outlet pipe. Exhaust gas in the second chamber exits the muffler through the second outlet pipe. The communication pipe may include first, second and third openings. The first opening is in communication with the first chamber. The second opening is in communication with the second chamber. The third opening is in communication with the third chamber. The first and second chambers may be in communication with the third chamber through the communication pipe.

Abstract: An exhaust system for receiving exhaust gas from an engine of a vehicle includes first, second, and third exhaust components, and first and second pipes. The first and second exhaust components are each adapted to receive exhaust gas from the engine. The first pipe has a first inlet, and first and second outlets. The first inlet is adapted to receive exhaust gas from the first exhaust component. The second pipe has a second inlet, and third and fourth outlets. The second inlet is adapted to receive exhaust gas from the second exhaust component. The third exhaust component is disposed downstream of and laterally between the first and second exhaust components. The third exhaust component has third and fourth inlets, and fifth and sixth outlets. The third inlet is fluidly connected to the first outlet. The fourth inlet is fluidly connected to the third outlet.
