  • Patent number: 6314926
    Abstract: A valve control apparatus is provided for an internal combustion engine having a valve and a camshaft. The camshaft has an axis of rotation, a first lobe and a second lobe adjacent to the first lobe. The second lobe is angularly spaced-apart about the axis from the first lobe. The apparatus includes a follower operatively engagable with the camshaft and the valve. The follower has a first operational mode where the first lobe operatively engages the follower on each revolution of the camshaft to open the valve a first time on each revolution. There is a mechanism for selectively putting the follower in a second operational mode where the second lobe operatively engages the follower to open the valve a second time on each revolution of the camshaft. The mechanism puts the follower in the second operational mode on each revolution of the camshaft before the second lobe is fully aligned with the follower.
