A common intake passage is provided for the intake valve and the second intake valve, and a separation wall extending from between the first intake valve and the second intake valve toward the upstream direction of the intake passage makes the intake passage known as the first intake passage. It is separated into a second intake passage, hangs downward from the upper wall surface of the intake passage, and extends from around the stem of the first intake valve along the axis of the first intake passage, beyond the upstream end of the separation wall, to the center of the common intake passage. A partition is formed in the intake passage that extends in the upstream direction of the intake passage until the end of the intake passage, and an intake control valve that opens during high engine load operation is arranged between the upstream ends of the partition on the side wall surface of the common intake passage on the second intake passage side. An intake system for an internal combustion engine, wherein a fuel injection valve is disposed in an intake passage downstream of the intake control valve, and fuel is injected from the fuel injection valve into a second intake passage.
