    Abstract: A control method for exhaust gas recirculation of a hybrid electric vehicle includes detecting a pressure of an intake manifold. A difference between the pressure of the intake manifold and atmospheric pressure is determined. A load of an engine, which generates torque by combusting a fuel and external air supplied through the intake manifold, is determined. An opening rate of an exhaust gas recirculation valve is controlled to be a first value according to a rotational speed of the engine when the difference is smaller than or equal to a reference pressure and the load of the engine is smaller than or equal to a reference load.

    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.

    Abstract: A method for controlling valve timing is provided for an engine including continuous variable duration (CVVD) device disposed on both intake valve and exhaust valve sides respectively. The method may include: classifying control regions into first, second, third, fourth, and fifth control regions based on engine load and speed; applying a maximum duration to an intake valve and controlling a valve overlap in a first control region, applying the maximum duration to the intake valve and exhaust valve in the second control region; controlling a manifold absolute pressure (MAP) of an intake manifold to be maintained consistently in the third control region; controlling a throttle valve to be fully opened, advancing an intake valve closing (IVC) timing, and controlling an exhaust valve closing (EVC) timing to after top dead center in the fourth control region; and controlling a wide open throttle valve (WOT) and retarding the intake valve closing in the fifth control region.
