INTAKE DEVICE OF INTERNAL COMBUSTION ENGINE

摘要

In an intake system 1 for an internal combustion engine wherein a partition plate 4A is provided within an intake pipe 3 in a longitudinal direction so that an inside is divided into a first intake passage 5, which is an upper side passage of the above described intake pipe, and a second intake passage 6, which is a lower side passage of the above described intake pipe, and an intake control valve 10 for opening and closing the second intake passage 6 is provided, the partition plate 4 has holes 9 which connect the first intake passage 5 to the second intake passage 6 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 5 in the intake system 1, an air flow toward the first intake passage from the second intake passage is created in the holes 9 so that the fuel FU that adheres to the partition plate can be sucked out.
