ABSTRACT:
A power unit comprises a Diesel engine supercharged by a turbocompressor which has a turbine receiving the engine exhaust gases. A by-pass pipe conveys the air not absorbed by the engine from the compressor to the turbine with a pressure drop which is independent of the flow rate and increases with the compressor outlet pressure. An auxiliary combustion chamber upstream of the turbine receives the air which has travelled through the by-pass. A throttle is disposed in the path of the supercharging air to the engine and is automatically actuated so as to maintain the flow rate of air absorbed by the engine at a value below the flow rate supplied by the compressor under low load conditions.
