Fuel rail

摘要

A fuel rail for the distribution of fuel to a plurality of fuel injectors is disclosed. The fuel rail includes a longitudinal conduit having injector sockets disposed at spaced intervals and a fuel inlet. Fuel is distributed through the conduit to the various injector sockets for delivery, through associated electromagnetic fuel injectors, to the intake system of an internal combustion engine. A compliant damper is disposed in the fuel conduit and is operable to lower peak pressure pulsations initiated by the firing of the fuel injectors. The fuel damper is supported within the conduit by a keyed damper support which engages the damper. The damper support is keyed with the conduit so as to position the damper axially and rotationally within the conduit to prevent interference with fuel flow to the injector sockets.
