Abstract
A control system for an internal combustion engine includes an electric supercharger that includes a compressor wheel that is configured to be rotated by an electric motor. The control system includes a bypass passage, a bypass valve, and an exhaust gas recirculation passage. The control device is configured to control the electric supercharger and the bypass valve based on an operation condition of the internal combustion engine. The control device is configured to cause a stepping operation of the electric supercharger in which acceleration and stopping of the compressor wheel are repeated within a predetermined cleaning time after operation of the internal combustion engine is stopped.
