<p>A drive assembly, especially for motor vehicles, of the type comprising an internal combustion engine and an exhaust gas turbine unit including an exhaust gas driven turbine is improved by virtue of structure for utilizing the heat energy of the exhaust gases of the internal combustion engine in addition to the kinetic energy. According to a preferred embodiment, the exhaust gas turbine unit comprises, in addition to the exhaust gas turbine, a compressor and a secondary turbine for deriving power from the heat energy of the exhaust gases. Still further, another feature includes the provision of a heat exchanger for transferring thermal energy from the exhaust gases to a working medium after the working medium has been compressed by the compressor, the heat exchanger being formed by hollow blades of the exhaust gas driven turbine.</p> |
