摘要： An intake port configuration (1) for an internal combustion engine wherein the swirl (D) of at least one intake flow entering the combustion chamber via an intake port controlled by an intake valve (5) can be varied, two or more flow paths are associated with at least one intake port, which paths join in the valve region (4), and the flow rate (Q) in at least one of the two flow paths is variable by means of a control element (9), and the two flow paths are constituted by two completely separate intake passages, i.e., a primary passage (2) and a secondary passage (3), the primary passage (2) having a helical form. In order to obtain a high flow rate (Q) at a high swirl level in addition to a wide range over which the swirl D may be varied, the intake valve axis (5a) intersects or is tangent to the secondary passage (3) at least at one point.
