PROBLEM TO BE SOLVED: To provide a control device for a compression-ignition internal combustion engine, which reliably switches an operation of the engine from a spark-ignition operation to a compression-ignition operation and which stably continues the compression-ignition operation.SOLUTION: The control device for the compression-ignition internal combustion engine includes an operation switching means for switching the operation of the compression-ignition internal combustion engine (engine) between the compression-ignition operation and the spark-ignition operation. The operation switching means starts the engine by the spark-ignition operation (S10), subsequently for switching the operation to the compression-ignition operation, performs a preparatory operation for the compression-ignition operation comprising an operation of increasing a throttle opening degree TH of the engine, an operation of retarding ignition timing, and an operation of controlling an air-fuel ratio in a lean direction (S16-S20), when a temperature Te of the engine reaches a predetermined temperature (S12 and S14), and switches the operation to the compression-ignition operation (S24) when the throttle opening degree TH becomes higher than a predetermined opening degree. |
