Abstract
In an intake system for an internal combustion engine wherein a partition plate is provided within an intake pipe in a longitudinal direction so that an inside is divided into a first intake passage, which is an upper side passage of the above described intake pipe, and a second intake passage, which is a lower side passage of the above described intake pipe, and an intake control valve for opening and closing the second intake passage is provided, the partition plate has holes which connect the first intake passage to the second intake passage and allow fuel on a lower surface of the partition plate to be sucked out to the first intake passage. When an intense tumble flow is created in the first intake passage in the intake system, an air flow toward the first intake passage from the second intake passage is created in the holes so that the fuel that adheres to the partition plate can be sucked out.
