Abstract
In a sequential turbocharger system having a first stage large volume turbo-charger and a second stage small volume turbocharger, a diaphragm actuator is provided for an exhaust bypass valve bypassing a turbine of the small volume turbocharger. The diaphragm actuator has a two step characteristic in relation to an opening of the exhaust bypass valve, so that an increased speed of opening of the exhaust bypass valve is obtained when the pressure downstream of the compressor of the first turbocharger is equal to the pressure downstream of the compressor of the second turbocharger.
