  • Fuel injectors are used in internal combustion engines to supply fuel to the combustion chambers of the internal combustion engine. For this purpose, a variety of designs for the realization of the metering of fuel are known. Fuel injectors are used both in Otto engines, so spark-ignited internal combustion engines and in internal combustion engines with auto-ignition, that is, in diesel engines or dual-fuel engines. The fuel injectors are often arranged in a bore of the cylinder head. It is also possible to provide the fuel injectors in Injektorhülsen, which in turn are used in the cylinder head of the internal combustion engine.

  • the heat shield serves on the one hand to protect the injector from heat and on the other hand as a seal between injector holder and the cylinder head.
  • Object of the present invention is to provide an arrangement with reduced heat input to the fuel injector. This object is achieved by an arrangement of a cylinder head and a fuel injector with the features of claim 1. Preferred developments are specified in the dependent claims.
