PURPOSE:To uniformly distribute fuel to cylinders of an engine, by providing a distributor and distribution pipes in a fuel injection device using one or two injection valves upstream of a throttle valve. CONSTITUTION:A body 22 of a distributor 21 is air-tightly formed by an outer wall 23 having a top wall 24 and a bottom wall 25. A fuel injection valve 9 is provided at a central portion of the top wall 24. Distribution pipes 20 are connected to the outer wall 23 in such a manner as to be arranged in equally spaced relation one another. Each of outlets of the distribution pipes 20 is connected to each of intake manifolds. When a rotor 28 accommodated in the body 22 is rotated at a fixed speed, the fuel injected to conically diverging from an injection nozzle of the injection valve is expelled through discharge holes 29 to a spacing 30 by a centrifugal force. As an inner wall of the rotor 29 is rotated, a fuel film having a uniform thickness is formed in the spacing 30, and is moved along the circumference of the rotor. Then, the fuel film is fed through the distribution pipes 20 to each of the intake manifolds by an engine suction vacuum. |
