PROBLEM TO BE SOLVED: To reduce the size of a fuel delivery pipe and bleed it of air efficiently by lifting restrictions in layout on it. SOLUTION: A fuel delivery pipe 15 for distributing fuel to injectors 4a to 4d provided for the respective cylinders of an engine 1 is angled up, as viewed from the front, at its portion between the two injectors 4a and 4b that are nearer to the connection of a fuel return pipe 8 such that its internal flow of air becomes smooth. A pressure regulator 7 is arranged at the crest to discharge the air outward efficiently. |
