Cylinder head with connected exhaust manifold of an internal combustion engine

A vehicle, comprising:

• an internal combustion engine having:
• a cylinder head assembly, comprising:
• a cylinder head having at least one exhaust duct that ends at an outer cylinder head connecting face;
• an exhaust manifold having an assigned exhaust manifold connecting face that is connected to the outer cylinder head connecting face of the cylinder head;
• at least one screw connection that connects the cylinder head to the exhaust manifold;
• a flange bushing insert inserted into the at least one exhaust duct of the cylinder head, having:
• a bushing part that has at least one radially protruding, circumferential bead as a spacer and sealing element with which the bushing part bears against an exhaust duct inner wall;
• and
• an end-side flange part that projects in an annular disc shape radially at an outer end of the flange bushing insert and is clamped directly between the outer cylinder head connecting face and the exhaust manifold connecting face without intervening elements, the flange part being supported axially with at least one circumferential, elastically formed bead, on the outer cylinder head connecting face, the flange part is clamped between the outer cylinder head connecting face and the exhaust manifold connecting face as at least one of a sealing flange and for axial bushing fixing, wherein the flange part projects axially in a direction of the exhaust manifold so that it clamps the flange part as a sealing element during mounting;
• and
• a circumferential thermally insulating gap that is uncoupled from an exhaust gas flow having a gap width corresponding to a bead height of the circumferential bead bounded by the exhaust duct inner wall, an outer wall of the bushing part, the flange part, and the at least one radially protruding, circumferential bead.
