摘要： To provide a control system for an internal combustion engine, which is capable of providing a stable intake air amount through reduction of pumping loss and blow-back of combustion gases by appropriately controlling the valve-opening timing of the intake valves, and thereby being capable of securing excellent drivability. In the control system 1, the valve-closing timing of the exhaust valve 9 is changed by an exhaust-side variable valve-operating mechanism 60, whereby the internal EGR amount is controlled, and the valve-opening timing of an intake valve 8 of an internal combustion engine 3 is changed by an intake-side variable valve-operating mechanism 40. Further, a target valve-opening timing CAINVO serving as a target of the valve-opening timing of the intake valve 8 is set such that the length of time from the top dead center of a piston 3b at the start of the intake stroke to the valve-opening timing of the intake valve 8 becomes equal to the length of time from the valve-closing timing of the exhaust valve 9 to the top dead center, and based on the target valve-opening timing, the intake-side variable valve-operating mechanism is controlled. Further, as the valve-closing timing of the exhaust valve 9, one of the detected actual valve-closing timing and the set target valve-closing timing is used.
