摘要:
A fuel injection device includes at least one fuel injector and a receiving bore in a cylinder head as well as a receiving opening of a fuel rail for the fuel injector. The fuel injector is sealed using at least one sealing ring against the walls of the receiving opening and secured in the receiving opening with the aid of a fastening element. A compensating element is provided that acts on the fastening element to prevent bending moments as a result of an asymmetrical suspension of the fuel injector at the fastening element from acting on the fuel injector. The fuel injector device is particularly suitable for directly injecting fuel into a combustion chamber of a mixture-compressing, spark-ignition internal combustion engine.
