Abstract

See full text

Systems and methods for selectively activating and deactivating gas exchange valves in a variable displacement internal combustion engine include a rocker arm having a positioning device that opposes movement of a lash adjustment device while deactivated to position a coupling hole of the rocker arm within a desired coupling range to facilitate coupling of the rocker arm during subsequent activation of an associated engine cylinder.
