How does the Wastergate valve work, and what is it for?
Years

Answer

In turbocharged internal combustion engines, the wastegate valve is a maximum pressure valve used to control the operating conditions of the turbine moved by the exhaust gases. It is positioned in the exhaust manifold (turbine side) and its opening is determined by the boost pressure on the compressor side. Its role is to prevent the supercharging system from being excessively stressed, keeping the turbine rotation speed within certain limits, thus also limiting the engine boost pressure on the intake side.
