    摘要： The present disclosure provides a system and a method for controlling valve timing of a continuous variable valve duration engine, including: classifying a plurality of control regions based on engine load and speed; applying a maximum duration to an intake valve and a long duration to an exhaust valve in a first control region; maintaining a maximum valve overlap in a second control region; advancing intake valve closing (IVC) timing and exhaust valve closing (EVC) timing in a third control region; applying a short duration to the exhaust valve and controlling the IVC timing to bottom dead center in a fourth control region; controlling a throttle valve to be fully opened, and controlling the IVC timing to an angle after BDC in a fifth control region; and applying the long duration to the exhaust valve, and controlling the IVC timing to prevent knocking in a sixth control region.

    摘要： A control method using a continuous variable valve duration apparatus implements a continuous variable valve duration apparatus which includes a wheel mounted on a camshaft and having a wheel key so as to control duration of an intake valve of an engine, a cam unit having a cam and a cam key, adapted such that the camshaft is inserted thereinto, and being disposed so as to vary relative phase of the cam with respect to the camshaft, an inner bracket connected with the wheel key and the cam key, a slider housing being adapted such that the inner bracket is rotatably inserted thereinto and disposed so as to move vertically with respect to the engine, a controller varying a position of the slider housing so as to adjust rotation center of the inner bracket, and a guide unit guiding motion of the sliding housing. The control method includes calculating a required air amount for maintaining idle rotation speed of the engine by the controller when the engine is an idle state; mapping a supplied air amount in accordance with duration of the intake valve or the exhaust valve by the controller; setting a target valve duration for supplying the required air amount of the engine by the controller; and controlling duration of the intake valve or exhaust valve according to the set target valve duration by the controller.

    摘要： A control method using a continuous variable duration apparatus provided to adjust opening duration of an intake valve of an engine includes: determining a reduction amount of a compression ratio to prevent knocking, when knocking of an engine is expected, setting a desired effective compression ratio required for the reduction amount of the effective compression ratio, setting desired duration for the set desired effective compression ratio, and controlling duration of the intake valve on the basis of the set desired duration.
