Reciprocating internal combustion engine supercharged by a turbocharger of which the compressor (10) is driven by a turbine rotor (7) supplied with burnt gases on the entire periphery thereof by a single distribution volute (6), this engine comprising two cylinder groups purged by two exhaust collectors (3) giving respectively into one of two convergent nozzles (4) parallel to the inlet direction of the volute (6) of the turbine and of which the collars (8) are adjacent and have cross-sections that are equal to that of the inlet (5) of the volute (6), the nozzles (4) being carried out at the volute by a convergent conical channel (9) of which the length is between 3 and 8 times the inlet diameter of the volute.
