ABSTRACT:
A fuel delivery pipe capable of reducing a pressure pulsation at the time of a fuel injection due to injection nozzles, preventing vibrations and noises at an underfloor pipe arrangement, and turning down a radiate sound from the fuel delivery pipe, wherein a flexible absorbing wall surface10formed on a wall surface of a fuel delivery body1is loosened due to internal pressure changes to render internal volume of the fuel delivery body1increasable, αL/√{square root over ( )}V determined by sonic speed αLof fuel flowing through the fuel delivery body1and the internal volume V of the fuel delivery body1is set as 20×103(m−0.5·sec−1)≦αL/√{square root over ( )}V≦85×103(m−0.5·sec−) while a ratio αL/αHof equivalent sonic speed αHin a high frequency area to the sonic speed αLof the fuel is set as αL/αH≦0.7, and the cross section shape in a perpendicular direction to an axis of the fuel delivery body1is formed in a substantially double side concaved shape, a substantially flask shape, a substantially trapezoid shape, a substantially key shape, and a substantially goggles shape.
