In an internal combustion engine, a two stage turbocharger is disclosed including a low pressure turbine and the high pressure turbine are arranged in series. The high pressure turbine is connected to an exhaust manifold of the engine through a high pressure turbine inlet duct. The low pressure turbine is connected to the high pressure turbine through a low pressure turbine inlet duct and to the high pressure turbine inlet duct through a connecting channel. The two stage turbocharger is provided with a bypass system including a high pressure turbine valve arranged in the high pressure turbine inlet duct, and a low pressure turbine valve arranged in the connecting channel. An actuator is configured to operate the high pressure turbine valve and the low pressure turbine valve to alternatively close the high pressure turbine inlet duct or the connecting channel.
