    摘要： In an internal combustion engine including an exhaust gas turbocharger and a compound power turbine connected to the crankshaft of the engine and an exhaust gas recirculation system extending between the engine exhaust duct upstream of the exhaust gas turbine and the intake duct downstream of the compressor of the exhaust gas turbocharger, the exhaust gas turbine and the compound power turbine have a size relationship determined by the power absorption capability &phgr; of each turbine such that: φ = m . ⁢ T p wherein: {dot over (m)} is the exhaust gas mass flow rate through the turbine, T is the exhaust gas temperature at the turbine inlet, and p is the exhaust gas pressure at the turbine outlet and the maximal compound power turbine absorption capability exceeds the maximal absorption capability of the exhaust gas turbine.

    摘要： In an exhaust gas turbocharger for an internal combustion engine, in which a compressor is disposed in the intake duct and a turbine is disposed in the exhaust duct, and wherein the turbine has a turbine wheel in a turbine housing with at least one inlet flow passage for the introduction of exhaust gas which flow passage is provided with a variable turbine geometry for the variable setting of the effective turbine inlet flow passage cross-section, the variable turbine geometry being adjustable between a shut-off position that minimizes the turbine inlet flow cross-section and an open position that maximizes the turbine inlet flow cross-section, a gas-collecting chamber is provided which is in communication with the inlet flow passage in the turbine housing, the total volume of flow passage and the gas-collecting chamber being adjustable by an actuator movably disposed in the turbine housing as a function of the operating state of the internal combustion engine.
