PURPOSE:To have good fuel distributing characteristic with simple configuration by arranging one injector, which has a plurality of jets and supplies fuel flow injected from each jet to inside of suction pipes, at each convergence of suction pipes leading to each cylinder downstream a throttle valve. CONSTITUTION:In case applied to a 4-cylinder engine, four suction pipes 20a-20d diverge from a suction pipe 20 at the convergence 20e corresponding to the cylinders, and upstream the convergence 20e, a throttle body 3 equipped in its inside with a throttle valve 4 is connected. One injector 10 is arranged at the convergence 20e of the suction pipe 20. This injector 10 is equipped at its metering plate with four jets inclined outside toward respective tips. Thereby fuel injection shall be made from the jets in the same direction as the suction as the suction flow to the suction pipes 20a-20d when current is supplied to the coil of injector 10 and the valve lifts.
