Abstract:
(EN) The invention relates to an internal combustion engine (42) for a motor vehicle, comprising at least one exhaust gas turbocharger (20), which has at least one turbine (20), drivable by exhaust gas of the internal combustion engine (10), and a first compressor, drivable by the turbine (20), for compressing air to be fed to at least one combustion chamber (14) of the internal combustion engine (1), and comprising an electrically operable second compressor (30), by means of which air to be fed to the at least one combustion chamber (14) can be compressed parallel to the first compressor (22), wherein the second compressor (30) is designed in at least two stages.
(FR) L'invention concerne un moteur à combustion interne (42) pour un véhicule à moteur. Le moteur comprend au moins un turbocompresseur (20), lequel présente au moins une turbine (20) pouvant être entraînée par les gaz d'échappement du moteur à combustion interne (10), et un premier compresseur (22) pouvant être entraîné par la turbine (20) et destiné à comprimer l'air à amener à au moins une chambre de combustion (14) du moteur à combustion interne (10), et un deuxième compresseur (30) à fonctionnement électrique, au moyen duquel l'air à amener à la ou aux chambres de combustion (14) est à comprimer parallèlement au premier compresseur (22), le deuxième compresseur (30) étant au moins à deux étages.
(DE) Die Erfindung betrifft eine Verbrennungskraftmaschine (42) für ein Kraftfahrzeug, mit wenigstens einem Abgasturbolader (20), welcher wenigstens eine von Abgas der Verbrennungskraftmaschine (10) antreibbare Turbine (20) und einen von der Turbine (20) antreibbaren ersten Verdichter (22) zum Verdichten von wenigstens einem Brennraum (14) der Verbrennungskraftmaschine (10) zuzuführender Luft aufweist, und mit einem elektrisch betreibbaren zweiten Verdichter (30), mittels welchem dem wenigstens einen Brennraum (14) zuzuführende Luft parallel zu dem ersten Verdichter (22) zu verdichten ist, wobei der zweite Verdichter (30) zumindest zweistufig ausgebildet ist.
