Abstract
A modular exhaust valve rocker arm assembly system comprising first and second rocker arm assemblies configured to each selectively receive a hydraulic lash adjustment assembly or a mechanical lash adjustment assembly. A main lifter assembly operably associated with the first and second rocker arm assemblies. An added motion lifter assembly operably associated with the first rocker arm assembly and configured to selectively provide one of an early lift profile and an extended lift profile, which can comprise at least one of an engine braking feature, a late intake valve closing (LIVC) feature, and an early exhaust valve opening (EEVO) feature. The main lifter can be configured as a fixed lifter or as a deactivating lifter for cylinder deactivation (CDA) configured to selectively move to a deactivated state configured to absorb motion of a normal lift profile cam into lost motion.
