Patent ID: 7836692

Claim:
An exhaust line element for a supercharged heat engine, comprising an exhaust manifold ( 12 ) and a turbocompressor ( 14 ) which comprises a chamber ( 18 ) for circulation of the exhaust gases which comprises a guiding bladed wheel therein and which has an inlet tube ( 20 ) for the exhaust gases, the manifold ( 12 ) comprising at least two separate inlets ( 33 ) equipped with connection means at the outlet of the cylinders of the engine and a discharge outlet ( 21 ) for the exhaust gases which is common to the different inlets ( 33 ) and which is connected to the inlet tube ( 20 ) of the turbocompressor ( 14 ), the manifold ( 12 ) comprising a bundle of internal tubes ( 42 ) which converge towards the outlet ( 21 ), each from an inlet ( 33 ) of the manifold, and an outer casing ( 40 ) inside which the bundle of tubes ( 42 ) extends, wherein the inlet tube ( 20 ) and the outlet ( 21 ) of the manifold are connected by means of a peripheral weld seam ( 48 ) which is provided between the outer casing ( 40 ) and the inlet tube ( 20 ) of the turbocompressor ( 14 ), and in that the bundle of tubes ( 42 ) is left free from any welding to the inlet tube ( 20 ) of the turbocompressor ( 14 ) at the outlet ( 21 ) of the manifold ( 12 ).
