Abstract
(DE)
Eine Anordnung zur Rückgewinnung ungenutzter Energie von Abgas (10) einer Verbrennungskraftmaschine (1) weist eine vom Abgas (10) angetriebene Ladeeinrichtung (6) zur Erzeugung komprimierter Ansaugluft für die Verbrennungskraftmaschine (1) und einen Luftkompressor (14) mit zumindest einer Verdichtungsstufe auf, welcher mit der Ladeeinrichtung (6) zur Entnahme von zumindest einer Teilmenge der komprimierten Ansaugluft verbunden ist, wobei die von dem Luftkompressor (14) entnehmbare Teilmenge der komprimierten Ansaugluft der Ladeeinrichtung (6) einstellbar ist, eine Verbrennungskraftmaschine (1) mit einer solchen Anordnung, sowie ein entsprechendes Verfahren dazu.
(EN)
A system for recovering the unused energy of exhaust gas (10) of an internal combustion engine (1) comprises a charge device (6), driven by the exhaust gas (10), for generating compressed intake air for the internal combustion engine (1), and an air compressor (14) having at least one compression stage, said air compressor being connected to the charge device (6) to withdraw at least a partial quantity of the compressed intake air, the partial quantity of the compressed intake air of the charge device (6) that can be withdrawn by the air compressor (14) being adjustable. The invention also relates to an internal combustion engine (1) comprising said system and to a corresponding method.
(FR)
La présente invention concerne un dispositif de récupération d'énergie non utilisée des gaz d'échappement (10) d'un moteur à combustion interne (1), présentant un dispositif de chargement (6) entraîné par les gaz d'échappement (10) et destiné à produire de l'air d'aspiration comprimé destiné au moteur à combustion interne (1), et un compresseur d'air (14) comprenant au moins un étage de compression qui est relié au dispositif de chargement (6) pour prélever au moins une quantité partielle de l'air d'aspiration comprimé, la quantité partielle de l'air d'aspiration comprimé, qui peut être prélevée par le compresseur d'air (14), étant réglable. L'invention a également pour objet un moteur à combustion interne (1) comprenant un tel dispositif et un procédé correspondant.
