物供給装置。In a spark ignition fuel injection internal combustion engine having one helical port-type intake port for each cylinder, an air-assisted fuel injection valve is installed in the cylinder head and is oriented toward the outer inner wall in the curved direction of the helical port. The intake pipe is connected to the intake pipe so as to be able to supply intake air, and the intake pipe is divided by a partition into a helical port, which includes a first intake passage adjacent to the outer inner wall and a second intake passage adjacent to the inner inner wall. An intake passage is formed, the cross-sectional area of the first intake passage is smaller than the cross-sectional area of the second intake passage, and the second intake passage has an intake passage that opens the second intake passage only when the engine rotates under high load and high speed. An air-fuel mixture supply device for a spark ignition fuel injection type internal combustion engine with helical port, characterized in that it is provided with a control valve.
