Abstract: PURPOSE: A variable charge motion valve system of an engine and a control method thereof are provided to remove noise generated when a variable charge motion valve strikes an intake body by minimizing a space between the variable charge motion valve and the intake body. CONSTITUTION: A control method of a variable charge motion valve system of an engine is as follows. It is confirmed whether an engine is started or not when an ignition is turned on(S1). If the engine is started, a space between a variable charge motion valve and an intake body is minimized by applying ignition torque to a drive motor(S2). It is confirmed whether the driving state of the engine is continued for a predetermined time(S3). If the engine is started over the predetermined time, the variable charge motion valve is opened by applying drive torque to the drive motor(S4). It is confirmed whether the engine is stopped(S6). If the engine is stopped, the variable charge motion valve is closed by applying stop torque to the drive motor(S7).
