Abstract
A power unit comprises an internal combustion compression ignited engine having variable-volume combustion chambers and supercharged by a turbocompressor having a turbine which receives the engine exhaust gases. A bypass pipe which is permanently open during operation of the engine returns the air not absorbed by the engine to the turbine with a pressure drop which, if appreciable, is independent of the flow rate and increases with the compressor outlet pressure. The power unit comprises a heat exchanger between the gas flow leaving the turbine and the air flow leaving the compressor. An air cooler is disposed in the path of the air travelling from the heat exchanger to the engine.
