Beschreibung
Zusammenfassung:	A control device for a compression self-ignition combustion engine is provided, which includes a variable valve operating system configured to introduce internal exhaust gas recirculation (EGR) gas into a combustion chamber, a boosting system configured to boost intake air, a controller configured to control the valve operating system, and a sensor connected to the controller and configured to detect a parameter related to an operating state of the engine. An operation mode of the valve operating system is switchable between first and second modes. The boosting system boosts the intake air when an engine load is higher than a given load, and does not boost when lower than the given load. When the engine load is high, the controller controls the valve operating system to operate in the first mode, and when the load is low, the controller controls the valve operating system to operate in the second mode.
