Abstract
(DE)
Die Erfindung betrifft eine Brennkraftmaschine, insbesondere Ottomotor, mit einem Abgasturbolader und einem mechanischen Lader (16), wobei im Luftkanal für Verbrennungsluft ein Verdichter (12) des Abgasturboladers stromauf des mechanischen Laders (16) angeordnet ist. Hierbei ist der Verdichter (12) des Abgasturboladers derart im Luftkanal für Verbrennungsluft angeordnet, dass der Verdichter (12) des Abgasturboladers direkt aus einem Luftfilter (28) Verbrennungsluft ansaugt, wobei stromab des Verdichters (12) des Abgasturboladers und stromauf des mechanischen Laders (16) ein erster Ladeluftkühler (14) sowie stromab des mechanischen Laders (16) ein zweiter Ladeluftkühler (22) angeordnet ist, wobei der erste Ladeluftkühler (14), der zweite Ladeluftkühler (22), der mechanische Lader (16) und ein Saugrohr (34) in einem einzigen Ladeluftkühlmodul angeordnet sind, wobei zur Zuführung von Kraftstoff eine Kraftstoffdirekteinspritzung in Brennräume der Brennkraftmaschine vorgesehen ist.
(EN)
The invention relates to an internal combustion machine, particularly a gasoline engine, having an exhaust gas turbocharger and a mechanical charger (16), wherein a compressor (12) of the exhaust gas turbocharger is disposed upstream of the mechanical charger (16) in the air channel for combustion air. The compressor (12) of the exhaust gas turbocharger is disposed in the air channel for combustion air such that the compressor (12) of the exhaust gas turbocharger draws combustion air directly from an air filter (28), and a first charge air cooler (14) is disposed downstream of the compressor (12) of the exhaust gas turbocharger and upstream of the mechanical charger (16), and a second charge air cooler (22) is disposed downstream of the mechanical charger (16), wherein the first charge air cooler (14), the second charge air cooler (22), the mechanical charger (16), and an air intake (34) are all disposed in a single charge air cooling module, wherein direct fuel injection is provided in combustion chambers of the internal combustion engine for the delivery of fuel.

La présente invention concerne un moteur à combustion interne, en particulier un moteur à allumage commandé, comprenant un turbocompresseur à gaz d'échappement et un compresseur de suralimentation mécanique (16), un compresseur (12) du turbocompresseur à gaz d'échappement étant disposé dans le canal à air de combustion, en amont du compresseur de suralimentation mécanique (16). Selon l'invention, le compresseur (12) du turbocompresseur à gaz d'échappement est disposé dans le canal à air de combustion de sorte que le compresseur (12) du turbocompresseur à gaz d'échappement aspire de l'air de combustion directement depuis un filtre à air (28). En aval du compresseur (12) du turbocompresseur à gaz d'échappement et en amont du compresseur de suralimentation mécanique (16) se trouve un premier dispositif de refroidissement d'air de suralimentation (14), et en aval du compresseur de suralimentation mécanique (16) se trouve un second dispositif de refroidissement d'air de suralimentation (22), le premier dispositif de refroidissement d'air de suralimentation (14), le second dispositif de refroidissement d'air de suralimentation (22), le compresseur de suralimentation mécanique (16) et un tube d'aspiration (34) se trouvant dans un module de refroidissement d'air de suralimentation unique. L'alimentation en carburant s'effectue au moyen d'une injection directe de carburant dans les chambres de combustion du moteur à combustion interne.
