Beschreibung
Zusammenfassung:	The method involves controlling an actuator element (D) arranged in a cold gas housing (11) in dependence on a pressure difference between an absolute pressure in a charge air duct (2) and an absolute pressure at a charge air side end cell, where the pressure difference is measured by a differential pressure sensor before entry of air into the charge air duct. The measurement of the pressure difference is carried out as high temporal resolution differential pressure measurement. An independent claim is also included for a pressure wave supercharger for an internal combustion engine. Die vorliegende Erfindung betrifft ein Verfahren zur Einstellung eines Ladedrucks einer Verbrennungskraftmaschine (A) sowie einen Druckwellenlader (B) für eine Verbrennungskraftmaschine (A), wobei ein Differenzdrucksensor (14) im Kaltgasgehäuse des Druckwellenladers (B) positioniert ist. Über den Differenzdrucksensor (14) lässt sich mit einem Stellelement der Druckwellenlader (B) erfindungsgemäß derart betreiben, dass die in der Zelle des Zellrotors des Druckwellenladers (B) befindliche Druckwelle bestmöglich in den Ladeluftkanal strömt und somit ein hoher Zylinderfüllgrad des Verbrennungsmotors erreicht wird.
