Abstract
A valve train assembly includes an intake rocker arm, an exhaust rocker arm, a carrier configured to couple to a cylinder block and operably associated with the intake rocker arm and the exhaust rocker arm, the carrier including a first aperture, and a cylinder deactivation (CDA) capsule disposed within the first aperture. The CDA capsule is configured to move between a latched condition that transfers motion from a push rod to one of the intake rocker arm and the exhaust rocker arm, and an unlatched condition that absorbs motion from the push rod and does not transfer the motion to the intake rocker arm or the exhaust rocker arm.
