  "textContent": "An intake-air quantity control apparatus for an internal combustion engine and a method for controlling an intake-air quantity entering each of engine cylinders for a computer-controlled internal combustion engine with a variable valve timing system associated with at least an intake valve (108) comprising: a control unit (113) for controlling an intake-air quantity of air entering the internal combustion engine on the basis of at least one of an intake valve open timing and an intake valve closure timing of the intake valve, said control unit comprises a desired internal pressure determined section (S503), a desired intake-air quantity arithmetic-calculation section (S502), a compensation section (S504) for compensating a desired internal pressure on the basis of at least the desired intake-air quantity to produce a compensated internal pressure, a throttle-opening control section (S505), and an intake-valve timing control section (S506) for controlling the intake valve open timing and the intake valve closure timing on the basis of both the compensated internal pressure and the desired intake-air quantity.",
