Castellation mechanism with reverse reset
Abstract:
A rocker arm assembly operable in an engine drive mode and at least one of a late intake valve closing (LIVC) mode and an internal exhaust gas recirculation (iEGR) mode, the rocker arm assembly selectively opening first and second engine valves. The rocker arm assembly includes a rocker arm configured to rotate about a rocker shaft, and a reverse reset capsule assembly movable between (i) a locked position configured to perform one of an LIVC operation and an iEGR operation, and (ii) an unlocked position that does not perform the LIVC operation or the iEGR operation. An actuator assembly is configured to selectively move the reverse reset capsule assembly between the locked and unlocked positions.
