The engine control unit regulates the level of the boost pressure via the opening time of the solenoid valve for charge pressure limitation. For control, a control pressure is generated from boost pressure in the compressor housing and the atmospheric pressure (ambient pressure).
This control pressure acts against the spring force in the wastegate (pressure box) and opens or closes the waste gate flap.
When de-energized, the solenoid valve is closed and the boost pressure acts directly on the pressure cell. The wastegate opens at low boost pressure.
We use exactly this wastegate valve in our racing cars, as well as in the converted private cars of our employees. It is thus tested on the racetrack, as well as on the road.
