Claims

[Scope of utility model registration request]

In response to the discharge pressure of the turbocharger compressor,
A system in which a wastegate valve is opened by the action of a boost pressure control actuator to bypass a portion of exhaust gas flowing through an intake passage of a turbine of a supercharger to an outlet of the turbine, the discharge passage of the compressor and the A supercharging pressure control system for an engine with a supercharger, the system forming a bypass passage communicating with an intake passage of a turbine, and providing a discharge air bypass valve operating in reverse to the waste gate valve in the bypass passage.
