In the case of selecting a turbine housing with a small area for the purpose of supplementing the lack of torque, the gasoline engine may create knocking in high speed. This device secures a solution to prevent this type of problem, where the exhaust gas is by passed at the turbine entrance that restraints the turbine revolution and provides the most suitable boost pressure.
