Abstract: An internal combustion engine comprises a cylinder and an intake passageway opening into the cylinder. In order to secure sufficiently high volumetric efficiency at high speed under high load operating conditions, the intake passageway is so configured as to pass therethrough a sufficient volume required for the combustible charge to be drawn into the cylinder per unit time. The intake passageway is provided with swirl means for causing the combustible charge passing through the intake passageway to swirl in the cylinder. The swirl means comprises at least one flow restrictor means so arranged as to urge the combustible charge to enter into the cylinder in a tangent direction to the cylinder wall. Control means is provided whereby the flow restrictor means reduces effective flow area thereof at low speed under light load operating conditions, thus securing strong swirl, and the flow restrictor means increase effective flow area thereof at high speed under high load operating conditions, thus securing high volumetric efficiency.
