Abstract
A control system for a turbocharger of an internal combustion engine, with the control system adapted to control a turbocharger having a turbine bypass valve in dependence upon a differential pressure between a turbo charging pressure supplied to a first pressure chamber and an atmospheric pressure supplied to a second pressure chamber. A pressure detecting device detects the turbocharging pressure, and pressure control valves shift the atmospheric pressure into the first pressure chamber of the pressure device and the pressure existing between a throttle valve of the engine and the compressor of the turbocharger in the second pressure chamber thereof, when the turbocharging pressure is less than a preset value.
