Abstract
The line control arrangement includes a valve timing controller generating a predetermined valve timing variable control signal according to an engine speed of a vehicle; and an oil controlling driver generating a rotational force in a predetermined direction according to the valve timing variable control signal received from the valve timing controller to form a corresponding advance line and a corresponding retard line. The line control arrangement for a continuously variable valve timing system reduces noise generated by operation of an oil controlling driver.
