Abstract
A control device for an internal combustion engine is configured, where a designated cam switching condition is met, to execute a boost pressure control processing and an air amount control processing. In the boost pressure control processing, the control device controls a boost pressure control device such that a boost pressure control parameter does not increase in synchronization with execution of a cam switching operation and decreases in accordance with an increase of a required engine torque after the execution of the cam switching operation. In the air amount control processing, the control device controls the opening degree of a throttle valve to its closed side in synchronization with the cam switching operation such that a difference of an in-cylinder charge air amount is not produced before and after the execution of the cam switching operation.
