Abstract

A coupling for routing and distributing exhaust gas flow from an internal combustion engine is disclosed. The coupling includes an upstream duct having a first end and a second end, and a gas flow distribution device arranged between the first and second ends of the upstream duct. The coupling also includes a downstream duct having a first end and a second end, and a flexible portion arranged between the first and second ends of the downstream duct. The upstream duct is fixed to the downstream duct to generate a continuous, sealed passage for the gas flow between the first end of the upstream duct and the second end of the downstream duct. A vehicle is also disclosed having an engine employing an exhaust after-treatment device and the coupling for routing and distributing the gas flow from the engine to the after-treatment device.
