Beschreibung
Zusammenfassung:	A fuel rail assembly for an internal combustion engine comprising a common fuel rail (2) forming a reservoir (4) for a fuel supply and a plurality of injector cups (6) spaced along the fuel rail (2) and each having a fuel passage (12) for hydraulically connecting an associated fuel injector to the common rail (2). Each fuel passage (12) comprises an inlet end (8) open to the common fuel rail and having a first upstream inlet section (14) having a predetermined length (L2) and a predetermined cross-sectional area such as to form a smoothing function to smooth pressure fluctuations in the fuel entering the passage (12).
