Abstract
A fuel rail includes an elongated tube having an inlet and a plurality of outlets. The elongated tube defines a fuel passageway for directing fuel toward the plurality of outlets. The fuel rail also includes a plurality of immovable baffles positioned within the elongated tube to divide the fuel passageway into a plurality of chambers such that each outlet is positioned in one of the plurality of chambers. The plurality of baffles restricts fluid flow between adjacent chambers. A majority of the plurality of outlets are located essentially at an acoustic node of each corresponding chamber to reduce noise generated by the fuel rail.
