An internal combustion engine (1), supercharged by a turbocompressor (3), comprises a bypass conduit (11) in which is placed an auxiliary combustion chamber (14). The primary zone (13) of this chamber (14) receives fuel whose flow is determined by regulating means (20). These means (20) vary this flow in the same direction as a parameter which is a characteristic of the load of the engine (1), in particular the temperature of the gases measured in the exhaust of the engine (1) by a sensor (22).

An internal combustion engine having work chambers of variable volume, supercharged by a turbocompressor whose air outlet of the compressor communicates with the air inlet of the work chambers, said compressor being driven by a turbine whose gas inlet is connected to the gas outlet of the work chambers through at least an exhaust manifold, which engine comprises a bypass conduit putting the air outlet of the compressor in communication with the gas inlet of the turbine through an auxiliary combustion chamber which is divided in the upstream to downstream direction into a primary combustion zone and a secondary dilution zone and whose gas outlet communicates with the inlet of the turbine, said primary zone comprising at least one fuel supply nozzle connected to a source of fuel under pressure through fuel flow regulating means for the fuel admitted by said nozzle, said regulating means being responsive to an operating parameter of the engine, wherein said regulating means are so arranged so as to act in the direction for increasing the fuel flow up to a maximum value, if at least a parameter characteristic of the thermal load of the engine exceeds, or has a tendency to exceed, a predetermined threshold TMAX, and in the direction for reducing the fuel flow down to a minimum value, if said characteristic parameter drops, or has a tendency to drop, below said threshold TMAX.
