Fuel rails (FRs) with integrated pulsation dampers prevent undesirable cabin noise. Such fuel rails were studied through a test vehicle evaluation on MPI returnless fuel supply systems. Among the alternative shapes of steel FRs, it was found that a flat or high aspect ratio rectangular cross section FR best absorbs the fuel pressure pulsations. In addition, the effect of the air-fuel ratio (A/F) was experimentally studied on pressure pulsation absorption in V and in-line engines.
