Abstract
Abstract An internal combustion engine with several cylinders and with one or several supercharging aggregates, in which at partial load of the engine, some cylinders operate as engine while the remaining cylinders, operating in the meantime as compressor, supply compressed gas to the turbine of a further supercharging aggregate whose compressor is connected in series with the compressor of that supercharging aggregate which supplies the cylinders operating as engine with supercharging air.
