Abstract

An exhaust device for a motor vehicle multi-cylinder internal combustion engine including a cylinder head of the engine in which there are exhaust ducts, a first end of each of which is connected to a combustion chamber of the engine and a second end of which opens into a cavity or plenum of an exhausted manifold integrated into the cylinder head of which an outlet duct is externally connected to a device for removing contamination from the exhaust gases of an exhaust line of the vehicle. The cavity or plenum of the manifold is formed in an element attached inside the cylinder head, and the element is thermally decoupled from the cylinder head using a thermal decoupling mechanism.
