Abstract
The internal combustion engine comprises a swirl control valve able to change a strength of a swirl generated in a combustion chamber; a load sensor for detecting an engine load; and a control device for controlling the swirl control valve. The control device controls the swirl control valve, when the engine load detected by the load sensor is lower than a predetermined load, so that the swirl ratio is higher when a suction intake gas amount is increasing, compared to when it is decreasing.
