1. A control method for an internal combustion engine that suppresses knocking by retarding ignition timing and adjusts an intake air amount by controlling a variable valve operating mechanism, which changes a maximum lift and a duration of an intake valve, comprising:
increasing a target value for the maximum lift and the duration of the intake valve, when increased an output request of the internal combustion engine, based on the amount of the required increased output and an actual air intake amount,
controlling the variable valve operating mechanism to increase the maximum lift and the duration of the intake valve to the target value; and,
changing the target value straight away, regardless of the actual air intake amount, to value which makes the valve closing timing of the intake valve become a timing which is after the bottom dead center and is spaced away from the bottom dead center, when the request output of the internal combustion engine is increased in a state in which the valve closing timing of the intake valve is before the intake bottom dead center.
2. The control method for an internal combustion engine according to claim 1, further comprising:
performing an adjustment of the intake air amount of the internal combustion engine by adjusting the opening amount of a throttle valve which is provided to an intake passage of the internal combustion engine, in addition to changing the maximum lift and the duration of the intake valve towards the target value, when the target value is changed straight away to value which makes the valve closing timing of the intake valve become a timing which is spaced away from the intake bottom dead center.
3. A control device for controlling an internal combustion engine that suppresses knocking by retarding ignition timing and adjusts an intake air amount by controlling a variable valve operating mechanism, which changes a maximum lift and a duration of an intake valve; comprising:

an controlling unit that controls the variable valve operating mechanism to increase the maximum lift and the duration of the intake valve to the target value; and,
an changing unit that changes the target value straight away, regardless of the actual air intake amount, to value which makes the valve closing timing of the intake valve become a timing which is after the bottom dead center and is spaced away from the bottom dead center, when the request output of the internal combustion engine is increased in a state in which the valve closing timing of the intake valve is before the intake bottom dead center.
4. The control device for controlling an internal combustion engine according to claim 3, further comprising:
an adjusting unit that performs an adjustment of the intake air amount of the internal combustion engine by adjusting the opening amount of a throttle valve which is provided to an intake passage of the internal combustion engine, in addition to changing the maximum lift and the duration of the intake valve towards the target value, when the target value is changed straight away to value which makes the valve closing timing of the intake valve become a timing which is spaced away from the intake bottom dead center.
5. The control device for controlling an internal combustion engine according to claim 3,
wherein the target value is changed to the value such that a compression ratio is low enough so that knocking is less likely to occur.
