吸気流量制御装置。A four-stroke engine is equipped with a rotary valve that has an opening on its outer periphery and opens and closes the intake passage by rotation in the intake passage upstream of the intake valve, and is equipped with a drive control means that slides the rotary valve in one direction. In,
Two openings of the rotary valve are provided per cylinder with a phase difference of 180 degrees on the circumference, and the shape of both openings is rotationally symmetrical with the axis of the rotary valve as the axis of symmetry.
