Abstract: A method for controlling intake and exhaust valves of an engine includes: controlling, by an intake continuous variable valve timing (CVVT) device and an exhaust CVVT device, opening and closing timings of the intake valve and exhaust valves; determining, by a controller, a target opening duration of the intake and exhaust valves based on an engine load and an engine speed; modifying, by an intake continuous variable valve duration (CVVD) device and by an exhaust CVVD device, current opening and closing timings of the intake valve and/or exhaust valve based on the target opening duration; and advancing or retarding, by the intake and/or exhaust CVVD devices, the current opening timing of the intake and exhaust valves while simultaneously retarding or advancing the current closing timing of the intake and exhaust valve by a predetermined value based on the target opening duration.

Abstract: A method for controlling intake and exhaust valves of an engine may include: determining, by a controller, a target opening duration of the intake and exhaust valves according to a control region determined based on an engine load and an engine speed; modifying, by an intake continuous variable valve duration (CVVD) device and by an exhaust CVVD device, opening and closing timings of the intake valve and exhaust valve based on the target opening duration of the valves; and advancing or retarding, by the intake and/or exhaust CVVD devices, the opening timing of the intake and exhaust valves while simultaneously retarding or advancing the closing timing of the intake and exhaust valve by a predetermined value based on the target opening durations. In particular, the controller classifies five control regions based on the engine load and speed.

Abstract: The present disclosure provides a system and a method for controlling valve timing of a continuous variable valve duration engine. The method may include: classifying a plurality of control regions depending on an engine speed and an engine load; applying a maximum duration to an intake valve in a first control region; maintaining the maximum duration of the intake valve and controlling a valve overlap by using exhaust valve closing (EVC) timing in a second control region; advancing intake valve closing (IVC) timing in a third control region; controlling the IVC timing to be close to bottom dead center (BDC) in a fourth control region; controlling a throttle valve to be fully opened and generating a scavenging phenomenon in a fifth control region; and controlling the throttle valve to be fully opened and controlling the IVC timing to prevent knocking in a sixth control region.
