Abstract
A method of controlling an engine system may include: method of controlling an engine system including a continuous variable valve duration (CVVD) apparatus, the method including: detecting data for controlling the engine system; determining whether a speed of an engine is less than a predetermined speed; determining whether a position value of an accelerator pedal is greater than a predetermined position value when the rotation speed of the engine is less than the predetermined speed; operating the CVVD apparatus to increase a valve overlap when the position value of the accelerator pedal is greater than the predetermined position value; and performing a knock control after the valve overlap is increased.
