Fuel Rail Assembly For An Internal Combustion Engine

摘要

The present disclosure relates to a fuel rail assembly for an internal combustion engine. In some embodiments, a fuel rail assembly for an internal combustion engine may include an elongated tubular fuel rail and a plurality of fuel delivery lines branching off from the fuel rail for hydraulically coupling the fuel rail to fuel injectors operable to inject fuel into the combustion engine. Also, an injector cup for receiving a fuel inlet portion of a respective one of the fuel injectors, a pipe arranged between the fuel rail and the injector cup for hydraulically coupling the injector cup to the fuel rail, and a fixation bracket configured for positionally fixing the fuel delivery line with respect to the engine. The injector cup, the pipe, and the fixation bracket are individual parts. A rigid connection is established between the fixation bracket and a portion of the pipe, said portion spaced apart from each of the fuel rail and from the injector cup. The fixation bracket is a one-pieced part which adjoins the pipe and is spaced apart from the injector cup and the fuel rail.
