Abstract
A fuel rail assembly (10, 50) for an internal combustion engine of a motor vehicle includes a fuel rail (12) defining a main fuel chamber (14) and a plurality of fuel injectors (20) attached to mounting collars (22) disposed within the fuel rail (12). The main chamber of the fuel rail (12) includes an integrally formed damper section (30) defining a cross-section of the main fuel chamber (14) that directs fuel flow transversely relative to the main chamber (14) to attenuate pressure pulsation within the fuel rail (12). The damper section (30) includes opposing first and second members (34, 36) offset relative to each other to form a fluid passageway transverse to the main fuel chamber (14).
