摘要： An engine intake control system that includes a first intake passage that has an upstream end portion and a downstream end portion opening in a surge chamber, a second intake passage that has an upstream end portion opening in the surge chamber so as to oppose the downstream end portion of the first intake passage across a gap, and a sleeve-shaped valve body slidably fitted around the downstream end portion of the first intake passage and moving between a first position in which it is distanced from the upstream end portion of the second intake passage and a second position in which it is in contact with the upstream end portion, wherein a linear motion guide bearing system is provided between an intake manifold and the valve body, a rail of the linear motion guide bearing system extending in a direction of movement of the valve body is secured to a support post fixedly provided on the intake manifold, and a slider movably straddle-mounted on the rail is secured to the valve body. Thereby an engine intake control system can realize smooth movement of a valve body even with lower machining precision for sliding faces of a first intake passage end portion and the valve body.

摘要： A valve operating system that includes a drive shaft, a drive lever that is fixedly provided thereon and can pivot in a direction of movement of a valve body, a follower arm that is fixedly provided on the valve body, a link, a first connecting shaft that connects one end of the link and the drive lever, and a second connecting shaft that connects the other end of the link and the follower arm; in response to a movement of the valve body from a first position to a second position by pivoting of the drive lever, a center of the first connecting shaft approaches from one side a straight line connecting two centers of the drive shaft and the second connecting shaft, and after the valve body reaches the second position, further pivoting of the drive lever is carried out through a predetermined angle so that the center of the first connecting shaft moves to the other side of a dead point on the straight line. Thereby a valve body can be held at one position with hardly any dependence on the output of an actuator, thus greatly reducing the load on the actuator.
