    Abstract: A system for selectively switching the action of a valve in an internal combustion engine includes a roller finger follower having a frame and a disengageable roller. A two-part axial pin for the roller axle is spring-loaded to urge the pin axially of the roller axle to disengage the first part of the pin from the follower frame and simultaneously disengage the second part of the pin from the roller axle. Thus the roller becomes detached from the frame and the follower cannot actuate its designated valve. The roller and pins are retained within the frame by at least one torsion spring. The pins may be controllably reinserted into the sides of the roller and frame to reconnect the roller to the frame by any of various electromechanical and/or hydraulic means. When used in conjunction with a camshaft having high lift and low lift cam lobes, the deactivated follower will then actuate its designated valve according to the profile of the low lift lobes, which may be a no lift profile.

    Abstract: Low mass hydraulic and mechanical valve lifters are shown and described. The lifters are of oblong configuration for reduced mass, with straight or narrowed sides connecting longitudinally spaced ends having depending semi-cylindrical end walls that are received in similarly shaped end portions of lifter gallery openings to absorb all longitudinal and lateral side loads. The lifters are preferably made by investment casting of steel alloys. The investment casting permits the use of thin semi-cylindrical walls at each end of the valve lifters which also have internal reinforcing ribs extending on their undersides.

    Abstract: A system for bringing an internal combustion engine to a stop at a predetermined angular position of an engine shaft, such as a crankshaft or a camshaft, with respect to the engine's valves. The optimum shaft stop position is the point wherein the fewest lifters are collapsed the least amount. Exemplary methods and apparatus include using the engine starter motor to jog the stopped engine to the desired position; using the engine alternator to impose a variable electromagnetic load on the engine to bring the engine to a stop at the desired position; using variable firing of cylinders to control the deceleration profile to bring the engine to a stop at the desired position; and providing one or more detents formed in the shaft and using a shaft follower to control the stop position of the shaft by engaging the follower into a detent.

    Abstract: A two-step roller finger follower including an elongate body having side walls defining coaxially disposed shaft orifices, a pallet end and a socket end interconnecting with the side walls to define a slider arm aperture, and a latch channel. The socket end is mountable to an hydraulic lash adjuster, and the pallet end is matable with a valve stem. A slider arm for engaging a high-lift cam lobe is disposed in the slider arm aperture and has a first end pivotably mounted to the pallet end of the body and the second end forming a slider tip for engaging an activation/deactivation latch. The latch is slidably disposed in the latch channel, and the latch has a nose section for selectively engaging the slider tip. A spool-shaped roller having first and second roller elements fixedly attached to the shaft is rotatably disposed in the shaft orifices, the roller being adapted to follow the surface motion of low-lift cam lobes. Preferably, the shaft is journalled in roller or needle bearings which extend between and through the first and second shaft orifices, being thus exposed to normal copious oil flow through the RFF.

    Abstract: A two-step finger follower rocker arm assembly including a follower body having a socket at a first end for engaging a hydraulic lash adjuster and a pad at an opposite end for engaging a valve stem. A passage through the follower body in the direction of actuation by an engine cam is slidingly receivable of a slider member for variably engaging a central high-lift lobe. A lost-motion spring urges the slider member into contact with the central lobe. A latch member driven by a piston selectively locks the slider member to the follower body, causing the follower to follow the motion of the central cam lobe. When the latch member is disengaged, the slider member slides within the follower body, allowing lateral rollers to follow lateral cam lobes. The lateral rollers may be supported on the body by a rotatable cross-shaft or a fixed cross-shaft, or by a pair of fixed stub shafts, or by a pair of fixed bearing races.

    Abstract: A control system for variable activation of valves in an internal combustion engine. A solenoid is disposed on the outer surface of the valve cam cover to avoid exposure to the hot-oil environment within the valve activation chamber. The solenoid armature extends through the cam cover into the valve activation chamber. A bellcrank is mounted between the solenoid armature and the latching pin of a latchable cam finger follower such that energizing and de-energizing of the solenoid causes corresponding actuation and deactuation of the finger follower, which may be suitable for high-lift and low-lift activation. Preferably, the bellcrank is compliant such that when the solenoid is actuated during the lift portion of the valve cycle the pin is placed under compression so that the pin is subsequently actuated into latching position when the follower moves to the base circle portion of the valve cam. Preferably, for a plurality of such systems on an individual engine, the solenoids are provided with connecting pins on an upper surface thereof and are held in place by a retainer containing an overmolded wiring bundle which automatically connects correctly to each solenoid upon installation of the retainer onto the engine.

    Abstract: A two-step finger follower rocker arm assembly including a follower body having a socket at a first end for engaging a hydraulic lash adjuster and a pad at an opposite end for engaging a valve stem. A passage through the follower body in the direction of actuation by an engine cam lobe is slidingly receivable of a slider member for variably engaging a central cam lobe, preferably a high-lift lobe. An elongate shaft extends through a transverse bore in the slider member and through a slotted passage in the slider member. In the follower body, the shaft is provided with bearings supporting first and second lateral roller followers on opposite sides of the body for variably engaging first and second preferably low-lift lateral cam lobes flanking the central cam lobe. A lost-motion spring urges the slider member into contact with the central lobe. A latch member driven by a piston selectively locks the slider member to the follower body such that the follower follows the motion of the central cam lobe. When the latch member is disengaged from the slider member, the member slides within the follower body, allowing the lateral rollers to engage and follow the lateral cam lobes. Preferably, the latching mechanism is provided as a pre-assembled cartridge unit.
