🔧 What This Actuator Does
The Valvetronic eccentric shaft actuator is an electric motor that adjusts the position of the eccentric shaft, which directly changes the intake valve lift. This allows the engine to control power output without using a traditional throttle butterfly, improving fuel efficiency and throttle response[reference:4].
