Patent ID: 7765051

Claim:
A device for controlling an internal combustion engine, comprising an intake control valve provided in an air-intake path at a position upstream from an intake valve, said intake control valve being controlled to be either in an operative state operating in relation to an operation said intake valve or in an non-operative state maintaining said air-intake path always open, and, in the operative state, closed at least prior to the opening of said intake valve and opened after the opening of said intake valve to generate a pressure difference between the upstream and downstream from said intake control valve; said device comprising a detector for detecting a value corresponding to an amount of intake air fed to said internal combustion engine, and correction means for correcting said value corresponding to the amount of intake air detected by said detector, in correspondence to the operation characteristics of said intake control valve when said intake control valve is in said operative state, wherein said correction means uses an opening timing of said intake control valve in correspondence to the opening timing of said intake valve among the operation characteristics of said intake control valve.
