What component operates the waste gate of a turbo-supercharger?

The waste gate actuator is the component responsible for controlling the waste gate of a turbo-supercharger. It plays a crucial role in managing the boost pressure produced by the turbocharger. When the engine reaches a specified boost level or when exhaust gas temperatures indicate potential overboost, the actuator opens the waste gate to divert exhaust gases away from the turbine side of the turbocharger. This action reduces the amount of turbocharger boost, which helps maintain engine performance and prevents damage from excessive boost pressure.

The waste gate actuator typically operates based on pressure signals from the intake manifold or boost control systems, ensuring that the turbocharger operates within optimal parameters. By effectively regulating the flow of exhaust gases, the waste gate actuator helps maintain efficient engine operation and performance while protecting engine components from damage due to high boost levels.
