Abstract

Die Erfindung betrifft eine Brennkraftmaschine mit mechanischer Aufladung, wobei ein Kompressor (1) über Verbindungselemente am Zylinderblock (3) abgestützt ist und wobei einige der dem Kompressor (1) zugeordneten Bauteile (4,5,9,10,11,12) mit Formschaum oder einem ähnlichen geräuschabsorbierenden Material zur Reduzierung der Schallabstrahlung ausgestattet sind. Es wird die Aufgabe gelöst, die vom Kompressor (1) bewirkte Schallabstrahlung durch Zuordnung spezifisch ausgestalteter Bauteile (4,5,9,10,11,12) mit geräuschabsorbierenden Eigenschaften zu reduzieren. Diese Aufgabe wird gelöst, indem dem Kompressor (1) saugseitig und druckseitig ein Pulsationsdämpfer zugeordnet ist und wobei der Kompressor (1), der saugseitige Pulsationsdämpfer und der druckseitige Pulsationsdämpfer jeweils mit einer Geräuschisolierung umhüllt sind, die jeweils ein inneres Bauteil (5;9;11) aus Absorptiongschaum und ein äußeres Bauteil (4;10;12) aus Kunststoff aufweist.
