Abstract: PROBLEM TO BE SOLVED: To solve the problem with a combustion engine having a turbo supercharger and a variable valve device which can adjust a valve overlap amount, wherein when setting the overlap amount on the basis of an actual suck-in air amount ITAC, a rise of supercharge pressure is delayed due to an effect that the valve overlap amount is not switched to the setting of scavenging importance when air-intake negative pressure is in the vicinity of atmospheric pressure in an acceleration transition period to an supercharging region from a non-supercharging region. SOLUTION: In the acceleration transition period to the supercharging region from the non-supercharging region, the actual suck-in air amount ITAC is increased by using an acceleration transition period suck-in air amount sITAC, and thus the valve overlap amount is increased toward the setting of the scavenging importance irrespective of the actual suck-in air amount ITAC.
