Abstract:
1. An internal combustion engine having a plurality of cylinders, comprising: an air intake line capable of carrying intake air towards the cylinders; an exhaust line capable of collecting exhaust gas from the cylinders; an exhaust gas recirculation (EGR) line capable of rerouting a part of the exhaust gas from the exhaust line towards the air intake line; at least a first turbocharger comprising a first turbine driven by the exhaust gas flowing towards the atmosphere, mechanically linked to a first compressor located on the air intake line; an exhaust gas recirculation (EGR) turbine located on the EGR line, the EGR turbine being solely driven by the exhaust gas recirculation (EGR) gas flowing in the EGR line; and a second compressor mechanically connected to the EGR turbine and capable of compressing gas flowing from an outlet of the first compressor toward the cylinders, the second compressor being arranged in parallel with an additional compressor located on the air intake line downstream from the first compressor.
