Actuation converts electrical signals from a control unit into an action, usually through electric motors or electromagnetic valves. In brake and steering systems, actuation adjusts flaps to regulate the flow of fluids and activate pumps to build up pressure. In engine control systems, it regulates idle speed, controls air flaps for torque and power optimization, and meters fuel for efficient combustion. In convenience systems, it can be used in locking systems or storage components for hands-free remote control.
In all these applications, consistent and reliable operation is critical, and lubrication can protect the moving parts from wear and damage.
