Abstract: A method for controlling valve timing of a turbo engine may include: classifying by a controller control regions depending on an engine speed and an engine load, and the control regions may include first, second, third, fourth, fifth, and sixth control regions. The method further includes: applying a maximum duration to an intake valve and controlling a valve overlap in the first control region; applying the maximum duration to the intake valve and exhaust valve in the second control region; advancing an intake valve closing (IVC) timing and an exhaust valve closing (EVC) timing in the third control region; approaching the IVC timing to a bottom dead center in a fourth control region; controlling a wide open throttle valve (WOT) in the fifth control region; and controlling the WOT and the IVC timing to reduce the knocking in the sixth control region.
