Abstract

PURPOSE:To improve intake efficiency throughout a wide speed range by spreading a tuning region of an inertia effect. CONSTITUTION:The first intake manifold 2a, corresponding to the first - third cylinders, and the second intake manifold 2b, corresponding to the fourth - sixth cylinder, are provided in an engine 1, whose fuel injection order is set to the first cylinder-fourth cylinder-second cylinder-sixth cylinder-third cylinder-fifth cylinder. Further a partitioning wall 5 is provided in the inside of an intake pipe 4 from the secondary side of an air cleaner 3 to the collective part of the intake manifolds 2a, 2b, and there are formed resonance passages 6a, 6b separately connected to the collective part of the each manifold 2a, 2b. Then a small hole 7, bypassing to communicate the both resonance passages, is provided in a half way of the partitioning wall 5. Accordingly, a diameter of the small hole 7 is selectively arranged, and suction efficiency similarized to characteristic in a full range of the resonance passages can be obtained at a low speed range.
