Abstract (en)
A fuel rail assembly (3) for an internal combustion engine (1) is disclosed. It comprises an elongated fuel rail (31), a plurality of injector cups (47) for hydraulically coupling the fuel rail assembly (3) to respective fuel injectors (7) and a pipe (41) assigned to each injector cup (47) for hydraulically coupling the respective injector cup (47) to the fuel rail (31). Each pipe (41) comprises an upper tube (43) and a lower tube (45). A fixation bracket (49) is assigned to each pipe (41) which is configured for positionally fixing the fuel rail assembly (3) with respect to the combustion engine (1) and is rigidly connected to the respective lower tube (45). A rigid connection (51) is established between a downstream end section (433) of the upper tube (43) and an upstream end section (451) of the lower tube (45). The downstream end section (433) of the upper tube (43) and the upstream end section (451) of the lower tube (45) are in engagement with one another in such fashion that, absent the rigid connection (51), the upper tube (43) and the lower tube (45) are rotatable with respect to one another around a predetermined rotational axis (R) . Further, a method for producing the fuel rail assembly (3) is disclosed.
