    摘要： An internal combustion engine has an exhaust gas turbocharger with an exhaust gas turbine and a compressor. In addition, an air-driven turbine is provided which is torsionally connected to the compressor and to which combustion air can be supplied via an adjustable shut-off element. For operation of the exhaust gas turbocharger over a wide operating spectrum, an additional duct is provided between compressor inlet and the air inlet of the air turbine, the air supply in the additional duct being adjustable by the shut-off element. In the lower load range, in the case where the required boost pressure falls below a threshold value, the additional duct is opened by means of the shut-off element and the air supply to the compressor inlet is reduced.

    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.
