Abstract

See full text

A method for controlling valve timing is provided for a turbo engine provided with a continuous variable valve duration (CVVD) device, a two stage variable valve duration device (VVD) and a continuous variable valve timing (CVVT) device. The method includes: classifying control regions; retarding an intake valve closing (IVC) timing and controlling an exhaust valve to limit a valve overlap in a first region; applying a maximum duration to an intake valve and applying a long duration to the exhaust valve in a second region; applying the long duration to the exhaust valve and advancing the IVC timing in a third region; controlling a throttle valve to be fully opened, applying a short duration to the exhaust valve and retarding an exhaust valve opening (EVO) timing in a fourth region; and controlling the throttle valve to be fully, applying the long duration to the exhaust valve and retarding the IVC timing in a fifth region.
