摘要：
An internal combustion engine includes a combustion chamber and a fuel injection valve that injects fuel directly into the combustion chamber, the fuel injection valve being situated in a cylinder head, and an annular sealing element being situated between the fuel injection valve and the cylinder head in order to seal the combustion chamber, and a shielding ring being situated between the sealing element and the combustion chamber in an axial direction of the fuel injection valve, the shielding ring being characterized in that it has a round cross-section or a cross-section that is rounded radially outward.
