Abstract
A helical type intake port is formed with the helical portion around an intake valve and the inlet portion tangentially contiguous to the helical portion. A bypass passage is provided in a cylinder head, which is branched off from the inlet portion and connected to an end portion of said helical portion. The flow in the bypass passage is controlled by a valve in response to the amount of air in the intake port so that a strong swirl flow with a slight flow resistance may be obtained at not only a low revolution and a low load, but also at a high revolution and a high load.
