PURPOSE:To make a device compact without reducing the supercharging effect by introducing compressed air from a turbosupercharger in the tangential direction through an expansion chamber midway on the suction passage and discharging it into a cylinder positioned in the tangential direction. CONSTITUTION:The compressed air generated by a turbosupercharger 9 flows into an expansion chamber 10, from its lower part on the opposite side to a cylinder head 6, through an introduction passage 11 and an inlet 10b, in the tangential direction of the first inner surface 10a and, after turning upward along the first inner surface 10a, the air is split into two at a splitting part 10c on the opposite side of the cylinder head 6. The air, then, is turned downward along the second inner surface 10d and discharged into each outlet introduction passage 12 through an outlet 10e which is opening in the tangential direction of the second inner surface 10d, and supplied to each cylinder from a suction port 3, after passing through an intake manifold 2a. |
