ABSTRACT:
A requested volume flow ratio calculated based on a requested torque, an amount of two times a spit-back gas amount at the valve overlap time calculated based on a requested residual gas rate, and a spit-back gas amount of the time when an intake valve is closed are added together, to set a requested valve passing gas amount of the intake valve, thereby determining a target operating characteristic of the intake valve based on the requested valve passing gas amount.
