Abstract

Die Erfindung betrifft einen Luftfilter für eine Brennkraftmaschine, mit einem Gehäuse (2), in dem ein Luftfilterelement (8) angeordnet ist, welches zwischen einem Rohlufteinlass (10) in einer Rohluftschale (4) und einem Reinluftauslass (12) in einer Reinluftschale (6) angeordnet ist, sowie mit einer im Luftfiltergehäuse (2) vorgesehenen Öffnung (13) , die durch ein luftdurchlässiges und feinmaschiges Gewebe oder durch ein dünnwandiges Schallelement abgedeckt ist.The invention relates to an air filter for an internal combustion engine, having a housing (2) in which an air filter element (8) is arranged between a unfiltered air inlet (10) in an empty air shell (4) and a clean air outlet (12) in a clean air shell (6 ) is arranged, and with an opening (13) provided in the air filter housing (2), which is covered by an air-permeable and fine mesh fabric or by a thin-walled sound element.

Es wird vorgeschlagen, dass zur Optimierung der Schallabstrahlung auf der Reinluftseite ein Resonator (18) vorgesehen ist, der in Abhängigkeit vorgebbarer Motorparameter zu- bzw. abschaltbar ist.
