Document Type and Number:

Japanese Patent JP3885599

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To solve a problem of air bleeding property, by securing a required clearance between a fuel delivery pipe and an under floor of a vehicle, effectively using a space between injectors, and preventing temperature difference in a fuel from being generated by stagnation.
SOLUTION: In a fuel supply device of an internal combustion engine, the longitudinal direction of the fuel delivery pipe having a plurality of injectors corresponding to a plurality of cylinders is set at a cylinder row direction. The plurality of injectors are mounted to the lower outer surface of a lower wall of the fuel delivery pipe, and a pressure regulator is mounted between the plurality of injectors.
