  • Patent number: 7789059
    Abstract: An intake control device for an air intake system includes one or more stationary intake pipes that communicate with one or more intake ports of an engine. One or more movable intake pipes are movable relative to the stationary intake pipes and, in one position, cooperate with the stationary intake pipes to define engine air intake passages. An actuator applies a force tending to move the movable intake pipes in a first direction. A controller controls the actuator. The movable intake pipes are inhibited from moving beyond a first position in the first direction. The controller directs the actuator to apply a force to the movable intake pipes when the movable intake pipes are in the first position.
