  • Publication number: 20090229248
    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.

  • Patent number: 6915634
    Abstract: A supercharger arrangement for an engine assembly 10 is disclosed, the arrangement including first and second superchargers 22A, 22B that are mounted on the engine assembly by means of separate first and second mounting members 46, 48 respectively. Each mounting member defines an integrated supercharger lubrication conduit 62A, 62B, 64A, 64B and the present invention is characterized in that the superchargers 22A, 22B are of substantially identical construction and are separable from the first and second mounting members 46, 48. The integrated lubrication conduits 62A, 62B, 64A, 64B are routed through their respective said mounting members in such a manner as to enable the first and second superchargers to be mounted on the engine assembly 10 in substantially mirror image orientations thereabout.
