Method for operating particle filter, particularly soot particle filter, involves applying filterelement or filter structure directly or indirectly with acoustic waves, so that filterlement or filter structure are kept particle-free

摘要

The method involves applying a filterelement or a filter structure (2) directly or indirectly with acoustic waves, so that the filterlement or the filter structure are kept particle-free. The acoustic waves lie within an ultrasonic range. A sound generation is acted or introduced directly on the filterlement or the filter structure.
