To provide an intake system for an internal combustion engine capable of improving the filling efficiency of the internal combustion engine by lowering an intake temperature, and of improving the output performance and fuel economy of the internal combustion engine.SOLUTION: An intake system 10 includes a guide member 21 for guiding travel wind to an intake port 11a, the guide member 21 having a bottom wall 22 located below the intake port 11a and extending to the front side further than the intake port 11a and the right side in a cylinder row direction L further than the intake port 11a, and a vertical wall 23 extending upward from one end in the cylinder row direction L of the bottom wall 22 and having at least part exposed to the intake port 11a in the cylinder row direction L. A volume part 17 is located behind a space 24 held among the bottom wall 22, the vertical wall 23, and the intake port 11a. The volume part 17 has an inclined surface 17a for guiding the travel wind flowing backward through the guide member 21 to the intake manifold 15 side.SELECTED DRAWING: Figure 1

    【課題】吸気温度を下げて内燃機関の充填効率を向上でき、内燃機関の出力性能と燃費を向上できる内燃機関の吸気装置を提供すること。【解決手段】吸気装置10は、走行風を吸気口11aに案内するガイド部材21を有し、ガイド部材21は、吸気口11aの下方に位置し、吸気口11aよりも前方側で、かつ、吸気口11aよりも気筒列方向Lの右方側に延びる底壁22と、底壁22の気筒列方向Lの一端部から上方に延び、かつ、少なくとも一部が気筒列方向Lで吸気口11aに対向する縦壁23とを有する。容積部17は、底壁22と縦壁23と吸気口11aとに挟まれる空間24の後方に位置しており、容積部17は、ガイド部材21を通して後方に流れる走行風を吸気マニホールド15側に導く傾斜面17aを有する。【選択図】図1
