Abstract
An inlet arrangement is provided for a multi-cylinder internal combustion engine. Each cylinder has an air inlet passage and a pair of inlet valves. A control flap is disposed within the inlet passage of one of the cylinders, the flap being pivotable about a pivot axle. The axle is disposed transverse to the length of the inlet passage. The flap has an operative position in which swirling of the air occurs and a starting position. The flap has a pair of wings provided on opposite sides of the pivot axle. The control flap has a base profile substantially corresponding to the internal profile of the inlet passage and a base area. One of the wings has a greater base area than the second of the wings. The first wing has a recess adjacent to the outer circumference of the wing. The recess, in the starting position of the control flap, faces away from direction from which the air flows.
