Abstract: The present disclosure provides a system and a method for controlling valve timing of a continuous variable valve duration engine. The method includes: classifying control regions based on engine speed and load; retarding intake valve closing (IVC) timing, applying a long duration to an exhaust valve, and limiting a valve overlap in a first control region; advancing the IVC timing, applying the long duration to the exhaust valve, and controlling the valve overlap in a second control region; applying the long duration to the exhaust valve and advancing the IVC timing in a third control region; controlling a throttle valve to be fully opened and applying a short duration to the exhaust valve in a fourth control region; and controlling the throttle valve to be fully opened, applying the long duration to the exhaust valve, and retarding the IVC timing in a fifth control region.
