How Does a Wastegate Valve Work?

Model: (Various brands) Various
Part: Valve

Video tutorial

On a car with a turbocharger, the wastegate valve is essential to prevent damaging the turbo itself. This video explains it in a very simple and understandable way. This valve regulates how much air pressure reaches the turbo because, obviously, a turbo cannot withstand infinite pressures, so it is necessary to use this type of valve, which is often integrated into the turbo housing.

The turbo allows more air to reach the engine, increasing the engine's power. Without this valve, you can understand that you would encounter excessively high pressures for both the turbo and the engine.
