Abstract

In an internal combustion engine having two exhaust gas turbochargers which are connected in series and a bypass line which bypasses the exhaust gas turbine close to the engine and extends to a collecting space of the turbine remote from the engine, and a blow-off valve is integrated into the turbine housing of the remote exhaust gas turbine for controlling a communication path between the collecting space and the turbine wheel, and includes a control sleeve supported axially movably between a closed position in which the communication path is blocked and a fully open position in which a flow path by-passing the turbine wheel of the turbine remote from the engine is provided.
