  "textContent": "A system and method control intake air of an internal combustion engine. The engine has at least one combustion chamber provided with intake valves together with an intake manifold provided with a throttle valve. The opening and closure timings of the intake valves are adjustable entirely independently by electromagnetic drivers from the crankshaft position to control the amount of intake air supplied to the combustion chamber. The system and method provide a response adjustment to variable valve timing control of the intake valves for unthrottled intake air control.",
