    Abstract: An object is to provide a turbo compound system that has high energy-saving efficiency and improved output or efficiency. In a turbo compound system including a plurality of exhaust turbochargers (3, 4), a power turbine (5), a steam turbine (10) driven by steam generated by an exhaust-gas economizer (11), a turbo-generator (25) connected to rotation shafts of the power turbine (5) and the steam turbine (10), and a control unit that controls an operation of the exhaust turbochargers (3, 4), the power turbine (5), and the steam turbine (10), one of the exhaust turbochargers (3) is stopped when an engine load on the engine body (2) is less than or equal to a predetermined value, and an amount of exhaust gas extracted from the engine body (2) is reduced to reduce an output of the power turbine (5).

    Abstract: A turbocharger system for an engine comprises at least a small and a large compressor arranged in series, at least a small and a large turbine arranged in parallel and a shut-off arrangement adapted to interrupt exhaust gas flow through at least one of the small and the large turbine. Further, a method for controlling a turbocharger system for an engine having a large turbocharger with a large turbine and a small turbocharger with a small turbine comprises the steps switching off an exhaust gas flow through the large turbine and switching on an exhaust gas flow through the small turbine in a low engine speed range, switching on the exhaust gas flow through the large and small turbine in a medium engine speed range, and switching on the exhaust gas flow through the large turbine and switching off the exhaust gas flow through the small turbine in a high engine speed range.
