An internal combustion engine comprising, for each cylinder, two intake ports, two intake valves installed in each of these intake ports, and an on-off valve installed in one of the intake ports that opens and closes according to engine operating conditions. In the intake system, a first fuel supply device supplies fuel to the intake port on the side where the on-off valve is not installed, and a first fuel supply device is provided upstream of the first fuel supply device and distributes fuel substantially equally to the two intake ports. a second fuel supply device for supplying fuel, and a second fuel supply device that operates only the first fuel supply device when the on-off valve is closed, and operates both the first and second fuel supply devices when the on-off valve is open; The fuel supply ratio of the first fuel supply device to the second fuel supply device is decreased in the medium speed range immediately after the switch is switched to open, and as the speed increases, the fuel supply ratio of the first fuel supply device is increased. An intake system for an internal combustion engine, comprising: control means for controlling.
