US 12,510,013 B2 · Air/exhaust system for a vehicle

Abstract

The disclosure provides an air/exhaust system for a vehicle, including a vented exhaust outlet with an inner tube and an outer tube having vents that draw air into a gap between the tubes to mix with exhaust from the inner tube and discharge cooled exhaust, an exhaust shield for reducing the noise emanating from the exhaust pipe, an exhaust collector with an inlet body, a neck body that causes the flow of the exhaust to converge and an expansion cone defining an expansion angle that improves distribution of exhaust flow across a catalytic converter. The catalytic converter has an inlet matrix brick formed from a foil that is thicker than a foil used to form an outlet matrix brick to improve the durability and performance. Finally, the system includes an intake duct with an interface having fingers that contact a frame member to inhibit wear of the intake duct.

Dependent claims

A catalytic converter, comprising:

a mantle tube defining a flow passageway from an inlet end to an outlet end;
an inlet matrix brick positioned within the flow passageway and including a matrix body having an inlet end adjacent the inlet end of the mantle tube and an outlet end, the matrix body formed from a first foil having a first thickness;
and
an outlet matrix brick positioned within the flow passageway and including a matrix body having an inlet end adjacent and spaced apart from the outlet end of the matrix body of the inlet matrix brick and an outlet end adjacent the outlet end of the mantle tube, the matrix body of the outlet matrix brick formed from a second foil having a second thickness;
wherein the first thickness is greater than the second thickness.
