Lifter Deactivation
The area of contact between the lifters and cam lobes is the highest loaded surface inside an engine.
The basic function of a valve lifter is pretty simple. It sits on the camshaft and transfers the motions of the cam lobe up through the pushrods and rockers to open and close the valves. The size and shape of the cam lobe under the lifter (multiplied by the ratio of the rocker arms) determine valve lift and duration. As such, the lifter just follows the motions of the cam. But, it does play a role in valvetrain lash (clearance) and noise.
