PURPOSE:To prevent the reduction of engine output and the increase of the harmful substance in exhaust gas by arranging the jetted-out fuel by a distributor and supplying said fuel into a cylinder through a distribution pipe which is installed for each cylinder and is equipped with a supersonic-wave vibrator. CONSTITUTION:The fuel sent into an injection valve 11 is jetted from an injection port 22 according to the driving signal supplied from a control unit 21, and forms two-phase stream in a distributor 23 together with the air which flows through an air passage 4, and flows into each distribution pipe 15 connected to each cylinder. In this case, the atomization of fuel is accelerated by a supersonic-wave vibrator 25 and jetted into an intake manifold 4, and mixed with the air which flows from a suction system 5, and sent into each cylinder 7. Therefore, fuel is uniformly distributed without receiving the influence of the injection state of fuel and the shape of the suction system. Therefore, the reduction of engine output and the increase of the harmful substance in exhaust gas can be prevented by an inexpensive means. |
