Abstract
(DE)
Die Erfindung betrifft eine Verbrennungskraftmaschine (10), mit einem von Luft durchströmbaren Ansaugtrakt (16), mit einem mit der Luft versorgbaren Brennraum (14), mit einem von Abgas aus dem Brennraum (14) durchströmbaren Abgastrakt (18), mit einem in dem Ansaugtrakt (16) angeordneten Verdichter (24) zum Verdichten der Luft, und mit einer Führungseinrichtung (48), mittels welcher in einem ersten Betriebszustand der Führungseinrichtung (48) zumindest ein Teil der den Ansaugtrakt (16) durchströmenden Luft aus dem Ansaugtrakt (16) abzweigbar und unter Umgehung des Brennraums (14) in den Abgastrakt (18) einleitbar ist und in einem zweiten Betriebszustand der Führungseinrichtung (48) zumindest ein Teil des den Abgastrakt (18) durchströmenden Abgases aus dem Abgastrakt (18) abzweigbar und in den Ansaugtrakt (16) einleitbar ist, wobei die Führungseinrichtung (48) eine von dem Abgas als auch von der in den Abgastrakt (18) einzuleitenden Luft durchströmbare Leitung (50) und einen in der Leitung (50) angeordneten Kühler (52) aufweist.
(EN)
The invention relates to an internal combustion engine (10), comprising: an intake tract (16), through which air can flow; a combustion chamber (14), which can be supplied with the air; an exhaust gas tract (18), through which exhaust gas from the combustion chamber (14) can flow; a compressor (24) arranged in the intake tract (16), for compressing the air; and a guide device (48), by means of which, in a first operating state of the guide device (48), at least some of the air flowing through the intake tract (16) can be diverted from the intake tract (16) and, bypassing the combustion chamber (14), can be introduced into the exhaust gas tract (18) and, in a second operating state of the guide device (48), at least some of the exhaust gas flowing through the exhaust gas tract (18) can be diverted from the exhaust gas tract (18) and can be introduced into the intake tract (16), the guide device (48) comprising a line (50), through which the exhaust gas can flow and the air to be introduced into the exhaust gas tract (18) can flow, and comprising a cooler (52) arranged in the line (50).
