Abstract
Eine Brennkraftmaschine, insbesondere für Kraftfahrzeuge, ist mit einer schalldämmenden Verschalung versehen, wobei die schalldämmende Verschalung eine den Zylinderblock im wesentlichen umgebende Ölwanne umfaßt, die durch Vibrationsdämpfungsglieder mit dem Zylinderblock verbunden ist. Zur Verringerung der Schallabstrahlung der Brennkraftmaschine umfassen die die Ölwanne mit dem Zylinderblock verbindenden Vibrationsdämpfungsglieder Befestigungs-Vibrationsdämpfungsglieder und Dichtungs-Vibrationsdämpfungsglieder.An internal combustion engine, in particular for motor vehicles, is provided with a sound-absorbing casing, the sound-absorbing casing comprising an oil pan which essentially surrounds the cylinder block and is connected to the cylinder block by vibration damping members. In order to reduce the sound radiation of the internal combustion engine, the vibration damping members connecting the oil pan to the cylinder block comprise fastening vibration damping members and sealing vibration damping members.
Description
Brennkraftmaschine 1 ausgehende Geräuschpegel erheblich reduziert wird.Internal combustion engine 1 outgoing noise level is significantly reduced.
In einer Weiterbildung der vorliegenden Erfindung ist es z. B. möglich, um eine Körperschallübertragung von der ölpumpe der Brennkraftmaschine an das öl in der ölwanne weitgehendst zu unterbinden, die ölpumpe und ihren Antrieb von der Brennkraftmaschine schallzuisolieren und das Pumpengehäuse ggf. aus Kunststoff herzustellen.In a further development of the present invention is it z. B. possible to a structure-borne sound transmission of the oil pump of the internal combustion engine to the oil in the Oil sump as much as possible to prevent the oil pump and soundproof their drive from the internal combustion engine and if necessary to manufacture the pump housing from plastic.
