<p>For means of reducing turbocharger lag when increased power is required from a so-equipped engine (7) operating at part load, its compressor (8) is provided with nozzles or directing devices (3) designed to increase the speed of the rotor when charge which has been previously compressed in the compressor (8) is recirculated to them. A heat source such as a heat exchanger (4) using waste heat from exhaust gases can be provided to heat the recirculating charge between the two pressure regimes, the increase in the energy of this recirculating charge between the two pressure regimes, the increase in the energy of this recirculated charge causing a further increase in the rotational speed of the rotor. The heat source equipped device can be operated at full load to increase compressor pressure ratio.</p> |
