摘要： 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.

摘要： 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.

摘要： A vehicle exhaust system includes a tubular component having an inner surface and an outer surface. The vehicle exhaust system also includes at least one opening defined by the tubular component. The at least one opening extends through each of the inner surface and the outer surface. The vehicle exhaust system further includes a patch adapted to cover the at least one opening. The patch includes a first portion extending parallel to the central axis. The first portion defines a plurality of pores. The first portion covers the at least one opening. The patch also includes a second portion extending away from the first portion. The first portion has a first thickness and the second portion has a second thickness.
