るエンジンの吸気装置。 A first intake passage having a short intake passage length and a second intake passage having a long intake passage length are formed so that the natural frequency of the air column within the intake passage matches the engine rotation speed, and the natural frequency of the air column within the intake passage corresponds to the engine rotation speed. In an engine intake system that performs inertial supercharging, the second intake passage is opened in the low rotation range, while the first intake passage is opened in the high rotation range, and the first intake passage is fully opened in the high rotation range. An intake system for an engine, comprising an intake control means for partially opening a second intake passage.
