Abstract (en)
[origin: WO2008135489A1] The invention relates to an internal combustion engine comprising a fuel chamber (4) and a fuel injection valve (3) that injects fuel (5) directly into the combustion chamber (4), the fuel injection valve (3) being disposed in a cylinder head (2). In order to seal the combustion chamber (4), a ring-shaped sealing element (6) is disposed between the fuel injection valve (3) and the cylinder head (2). A shield ring (7) is disposed in an axial direction (X-X) of the fuel injection valve (3) between the sealing element (6) and the combustion chamber (4), which is characterized in that it has a round cross section or a cross section that is rounded radially outward.
