  "textContent": "A valvetrain system may include a rocker arm assembly actuatable between a drive mode defining a drive valve lift profile of an engine valve, and a cylinder deactivation mode defining a recharge valve lift profile of the engine valve. The recharge valve lift profile begins after the drive valve lift profile. The recharge valve lift profile defines a recharge lift amplitude that is less than a drive lift amplitude. The recharge valve lift profile ends within 15% of an end of the drive valve lift profile. The recharge valve lift profile is defined entirely within the drive valve lift profile so that: when the rocker arm assembly is in the drive mode, movement of the engine valve is dictated by the drive valve lift profile, and when the rocker arm assembly is in the cylinder deactivation mode, movement of the engine valve is dictated by the recharge valve lift profile.",
