Abstract: An internal combustion engine having a plurality of intake and/or exhaust valves associated with each cylinder includes a valvetrain having a fulcrum with a plurality of pivot ball sockets each associated with a rocker arm and pivot ball disposed between the fulcrum and the rocker arm with the fulcrum extending through apertures of the rocker arms and having a plurality of slots, each slot having generally parallel opposing lateral surfaces for receiving and guiding both sides of an associated rocker arm so the rocker arm pivots about the pivot ball in a plane of the rocker arm. The fulcrum can accommodate at least two rocker arms that may operate in non-parallel planes relative to one another and can include bearing and locating surfaces integrally formed to finish dimensions to eliminate machining.

Abstract: A system and method for securing a fuel injector in an internal combustion engine include a clamp for securing adjacent injectors to a cylinder head. The clamp includes a central portion with a hole for receiving a fastener to secure the clamp to the cylinder head, and a pair of symmetrical crescent-shaped clamping forks forming a U-shaped opening to facilitate lateral sliding engagement with diametrically opposed flatted portions of corresponding fuel injectors. Each arm includes an arcuate pad that engages a corresponding shoulder of the fuel injector to provide an axial clamping force to the fuel injector. The distance between the distal ends of one fork and the semicircular portion of the opposite fork is selected to allow lateral sliding disengagement of the clamp from one of the adjacent injectors without rotation or removal of the other injector to facilitate servicing of individual injectors.

Abstract: An internal combustion engine with selectively deactivated intake and/or exhaust valves includes a fulcrum plate having a through hole with a slidable plunger supporting a pivot ball that engages an associated rocker arm. A solenoid positioned above the rocker arm cover is directly coupled to a latching mechanism that either allows or prevents sliding movement of the plunger to selectively deactivate associated intake/exhaust valves. When in the valve activated position, the rocker arm pivots about the pivot ball and opens the valve. When in the valve deactivated position, the plunger retracts at least partially into the fulcrum plate so that the rocker arm motion is insufficient to open the associated valve. A lost motion torsional spring acts on the plunger to provide an opposing force to the rocker arm and to return the plunger to the valve activated position during the base circle portion of camshaft rotation.
