<P>PROBLEM TO BE SOLVED: To provide a fuel injection rail which can improve performance of absorbing pressure fluctuation of fuel and strength resistance against a high pressure. <P>SOLUTION: A fuel delivery pipe includes a body part 10 having a plurality of injector cups 17 for mounting an injector arranged in a length direction. A surface having a maximum displacement point by the pressure fluctuation out of the respective surfaces for forming the body part of the fuel delivery pipe has a polygonal planar shape (except for a rectangular shape). <P>COPYRIGHT: (C)2010,JPO&INPIT |
