Abstract: An apparatus includes a valve and an actuator. The valve has a portion movably disposed within a valve pocket defined by a cylinder head of an engine. The valve is configured to move relative to the cylinder head a distance between a closed position and an opened position. The portion of the valve defines a flow opening that is in fluid communication with a cylinder of an engine when the valve is in the opened position. The actuator is configured to selectively vary the distance between the closed position and the opened position.

Abstract: A two-piece intake assembly such as a coaxial poppet valve includes a main poppet valve with a stem attached to a head and an auxiliary poppet valve movable on the inner valve. A guiding element on the outer valve is configured to receive the inner valve stem, and is connected to an outer valve head configured to mate with the inner valve head and form a seal. The assembly provides a first vent opening formed by the action of a rocker arm on the inner valve stem and a second opening formed by the pressure differential between the combustion chamber and the intake port.

Abstract: A valve control system (15) in which there is provided a deactivating rocker arm (51) disposed beneath a conventional, upper rocker arm (27), and disposed within a module housing (17). The deactivating rocker arm includes a latch tab (63) and when the latch tab engages (FIG. 3) a latch member (65), the system operates in a normal, valve activating mode. When the latch member is in an unlatched condition (FIG. 4), the deactivating rocker arm pivots, compressing the valve return spring (41), which thereafter serves as the required lost motion spring, biasing the deactivating rocker arm (51) and lash compensation device (35) back toward their normal position.
