Abstract
A helical type intake port for an internal combustion engine. The system has a first sub-intake passageway and a second sub-intake passageway. The first sub-intake passageway is connected to a helical end of the intake passageway for generating a flow of air for suppression of the swirl effect in the helical end. The second sub-intake passageway is connected to a portion of the helical port located upstream of the helical end portion, for increasing the speed of flow of air directed to the helical end portion.
