The fuel connector includes an outer connector surface having an unthreaded base section, and an externally threaded end section adjacent to the terminal connector end.

A cylinder head for an internal combustion engine, in particular a hydrogen-powered internal combustion engine, includes a cylinder head system that includes an intake duct and a fuel inlet aperture, the fuel inlet aperture opening into the intake duct, an injector holder that is detachably connected to the cylinder head system and that includes an injector receiving borehole, an injector that is accommodated in the injector receiving borehole and braced against the injector holder with the aid of clamping means, and a tubular plug-in piece that is situated between the injector holder and the cylinder head system in such a way that a discharge opening of the injector and the fuel inlet aperture of the cylinder head system are fluidically connected to one another via the via the plug-in piece.

A bracket for clamping an injector onto a cylinder head of an internal combustion engine, comprising a clamp section, arranged for providing a clamping force onto the injector to clamp the injector onto the cylinder head; a mount section, extending from the clamp section and arranged for mounting the bracket to the cylinder head adjacent the injector; and a support section, extending from the mount section opposite the clamp section and arranged for supporting the bracket onto the cylinder head at a lever distance from the clamp section, to define the clamping force; wherein the support section comprises a plurality of support elements, each of said support elements arranged at a different lever distance, such that a selected support element from the plurality of support elements engages, in use, with the cylinder head at a selected lever distance, such that the bracket is supported on the selected support element only, to control a magnitude of the clamping force.

A fuel distributor which has a pressure accumulator rail for receiving pressurized fuel. The pressure accumulator rail has a forged base body. Mounting supports are joined to the base body by substance bonding. A mounting support is formed by two metal brackets each configured as a sheet-metal formed part. Each metal bracket has a holding portion adapted to the outer contour of the base body, a leg angled relative to the holding portion, and a mounting flange on the free end of the leg and angled away therefrom. A length portion of the base body is received between the holding portions. The holding portions partially surround the base body. The base body and the holding portions are joined by substance bonding. The legs of the two metal brackets lie next to each other at least in regions and are also joined together by substance bonding.
