What does a wastegate do?

The wastegate’s job is to divert excess exhaust gases away from the turbine – controlling the speed of the turbine and preventing it from spinning too fast.

By controlling and limiting the speed of the turbine, the wastegate regulates the boost pressure provided by the turbocharger. By preventing the boost pressure from rising indefinitely, the wastegate protects the turbocharger and the engine from damage.

How does a wastegate work?

In most cases, a wastegate is a relatively simple valve, controlled by a pressure actuator linked to the boost pressure of the turbo.

The wastegate is held shut by a spring inside the actuator, but when the boost pressure exceeds the pre-set maximum, it compresses this spring, progressively opening the wastegate. This allows the exhaust gases through, so that they bypass the turbine, regulating its speed.
