Abstract
A control system for a spark-ignition internal combustion engine configured to produce tumble flow in a cylinder is provided. The spark-ignition internal combustion engine includes an ignition plug configured to ignite an air-fuel mixture in the cylinder. The control system includes a tumble flow rate controller configured to change a position of a vortex center of the tumble flow as viewed in a direction of a center axis of the cylinder, so as to control a flow rate of the tumble flow around the ignition plug at the ignition timing of the ignition plug.
