Abstract
A fuel delivery rail assembly for supplying fuel to a plurality of fuel injectors in an engine includes an elongated conduit having a longitudinal fuel passage therein, a fuel inlet pipe, and a plurality of sockets. One wall of the conduit opposite to the socket mounting wall includes a flat or arcuate flexible absorbing surface. A high-frequency noise suppressing component such as a rib, a cavity or a clamp is applied to the one wall opposite to the absorbing surface. Thus, fuel pressure pulsations and shock waves are reduced by bending the absorbing surface, and emission of high-frequency noise is eliminated.
