造。[Scope of Claim for Utility Model Registration] A turbocharged internal combustion engine comprising a throttle valve, a supercharger connected to the upstream side of the throttle valve, and a bypass passage communicating the discharge side and suction side of the supercharger. A supercharging pressure control structure in which the bypass passage includes a first control valve that interlocks with the throttle valve so as to close as the throttle valve opens; It has a flow area larger than the passage,
and a second bypass passage provided with a second control valve that responds to the supercharging pressure so as to open when the supercharging pressure exceeds a predetermined value. Boost pressure control structure for internal combustion engines.
