Wastegate Valves / Actuators

Description

The waste gate valve was created to make the turbo run faster at low revs with a small size turbine housing, without reaching too high pressures at high rpm. In fact, a small turbine housing allows the turbo to spin sharply from the lower engine revs. Obviously when the engine expels a considerable amount of gas at the top, the narrow turbine housing becomes a bottleneck that prevents the engine from going up and down and at the same time, it makes the shaft wheel to rotate too hard. The problem is solved by providing the turbine housing with the waste gate valve, controlled by an actuator. The actuator feels the supercharging pressure through a tube connected to the compressor housing and it moves the waste gate plate opening an air inlet before the compressor wheel.

The gases and the power generated are sent directly to the evacuation so they are not released to the turbo. In this case the turbocharger revs are limited and as a consequence the supercharging pressure is also stabilized.
