Abstract:
A method of controlling an internal combustion engine havinga valve mechanism including an intake valve and an exhaust valve associated, respectively, with an intake port and an exhaust port of a cylinder of the internal combustion engine;a valve mechanism controller configured to control said valve mechanism;an operation condition detector for an operation condition detection of the internal combustion engine; anda throttle valve for controlling an intake amount in response to an operation amount of an acceleration pedal;comprising the steps of;controlling said throttle valve to a high opening degree condition independently of said operation amount of said acceleration pedal when said operation condition detector judges as a low load or a middle load of the operation condition of the internal combustion engine; andcontrolling the intake amount by controlling at least one of a valve closing timing and a valve lift amount of said intake valve.
