Abstract: A camshaft for an internal combustion engine includes a cam lobe for actuating a valve. The cam lobe has an opening ramp profile that acts to loft the valve gear away from contact with the cam lobe to a maximum lift of the valve, with the valve gear returning to contact with a closing ramp of the cam lobe sufficiently in advance of a minimum cam lobe closing ramp height so as to dissipate enough closing energy of the valve to minimize valve bounce after the valve contacts a corresponding valve seat.

Abstract: A double roller cam follower includes a longitudinal beam having a first end and a second end, a cam roller rotationally mounted on the beam for engaging a cam lobe and a valve stem roller rotationally mounted on the second end of the beam for engaging a valve stem. The cam roller includes a stepped outer circumference having a larger diameter at its sides to engage the cam lobe and a smaller diameter positioned centrally between the flanking larger diameters to provide clearance between the cam roller and the valve stem roller.
