Updated: Feb 1

✔ This article has been fact checked.

A wastegate is a valve that is used to control the amount of exhaust gases that flow through the turbine in a turbocharged engine. It helps to regulate the boost pressure of the engine and prevent it from overboosting.

The wastegate regulates the flow of exhaust gases through the turbocharger by opening and closing at a predetermined boost pressure. When the boost pressure becomes too high, the wastegate opens to release excess exhaust gases.

In this article, we will explore how a wastegate works and the various types that are available.
