ABSTRACT:
A method of controlling an internal combustion engine includes mechanism including an intake valve and an exhaust valve provided respectively to an intake port and an exhaust port of a cylinder of the internal combustion engine, a valve mechanism control means for controlling said valve mechanism, an operation condition detection for detecting an operation condition of the internal combustion engine, and a throttle valve for controlling an intake amount in response to an operation amount of an acceleration pedal. When the method of the internal combustion engine, wherein when the operation condition detector judges as a low load or a middle load of the operation condition of the internal combustion engine, the throttle valve is controlled to a high opening degree condition regardless of the operation amount of the acceleration pedal, and by controlling a valve closing timing and/or a valve lift amount of the intake valve, the intake amount is controlled. A pumping loss during a low and a middle load conditions can be reduced widely, a fuel consumption can be improved and further during a high load condition knocking can be prevented.
