Patent ID: 8312850

Claim:
A valve train control device for use in a reciprocating piston internal combustion engine having a camshaft with a primary cam lobe defining a primary cam lobe profile constructed to directly or indirectly translate camshaft rotational motion into linear motion of a corresponding valve in accordance with the profile, the device comprising: a primary cam follower positioned in an operational path between the primary cam lobe and the corresponding valve, the primary cam follower constructed to follow the primary cam lobe; a secondary cam lobe projecting from the camshaft; a secondary cam follower constructed to follow the secondary cam lobe; and an auxiliary motion transfer device with a linkage, including a lever component, pivotally coupling the secondary cam follower to a first region of a reciprocating motion transfer arm and the reciprocating motion transfer arm having a second region pivotally coupled to the primary cam follower, the motion transfer device being responsive to at least one engine parameter to shift the primary cam follower during at least a portion of the camshaft rotation to alter at least one valve operating parameter relative to a set of valve parameters defined by the primary cam lobe profile interacting with an unshifted primary cam follower.
