A turbocharged internal combustion engine comprises an intake air passageway in which a throttle valve is pivotally disposed. A turbocharger compressor wheel is disposed in the intake air passageway upstream of the throttle valve. An intake air bypass passageway is connected to the intake air passageway bypassing the throttle valve and provided with an air regulator. Additionally, a check valve is disposed in the bypass passageway downstream of the air regulator to prevent intake air from its reverse flow in a direction from the intake air passageway downstream of the throttle valve toward the air regulator, thereby avoiding lowering in supercharging efficiency of the turbocharger. |
