Abstract

Effective means of further improving the acoustic properties of internal combustion engines is the use of high damping materials such as cellular aluminium. Studies of acoustic material properties have been made at the Acoustic Competence Centre Graz (ACC) in cooperation with AVL List GmbH. A new method of power flow analysis was developed and both the usability and the acoustic potential have been verified by means of prototypes of an oil sump.
