Abstract
The utility model provides a changeable intake manifold. The changeable intake manifold comprises an intake valve, a pressure stabilizing cavity, a short and thick air channel used for connecting the pressure stabilizing cavity with the intake valve, and a long and thin air channel used for connecting the pressure stabilizing cavity with the intake valve. The changeable intake manifold further comprises a cylindrical roller, and a through air channel hole is formed in the cylindrical roller in the radial direction. The cylindrical roller is arranged on the short and thick air channel and can open or close the short and thick air channel by rotating around the axis of the cylindrical roller.
