Abstract

Verfahren zur Einstellung eines Ladedruckes einer Verbrennungskraftmaschine (A), wobei der Ladedruck durch einen Druckwellenlader (B) aufgebaut wird, welcher einen Zellrotor und ein Zellrotorgehäuse aufweist und an den Druckwellenlader (B) ein Kanal 1 (1) zum Ansaugen von Frischluft, ein Kanal 2 (2) zum Abführen der komprimierten Frischluft, ein Kanal 3 (3) zum Zuführen von Abgas und ein Kanal 4 (4) zum Abführen von Abgas angeschlossen sind und der Druckwellenlader (B) ein Kaltgasgehäuse, an dem Kanal 1 (1) und Kanal 2 (2) angeschlossen sind, und ein Gastaschenventil (F), das im Bereich des Kanal 3 (3) angeordnet ist, aufweist, und im Kaltgasgehäuse ein Stellelement zur Einstellung von Querschnittsflächen der Kanalöffnungen angeordnet ist, dadurch gekennzeichnet, dass eine Position des Stellelements in Abhängigkeit einer Differenz der Gastaschenventilstellung eingestellt und/oder geregelt wird.

Figure imgaf001
A method for adjusting a boost pressure of an internal combustion engine (A), wherein the boost pressure is built up by a pressure wave supercharger (B) having a cell rotor and a cell rotor housing and to the pressure wave supercharger (B) a channel 1 (1) for sucking fresh air, a channel 2 (2) for discharging the compressed fresh air, a channel 3 (3) for supplying exhaust gas and a duct 4 (4) for discharging exhaust gas are connected and the pressure wave supercharger (B) a cold gas housing, on the channel 1 (1) and Channel 2 (2) are connected, and a gas pocket valve (F), which is arranged in the region of the channel 3 (3), and in the cold gas housing, an adjusting element for adjusting cross-sectional areas of the channel openings is arranged, characterized in that a position of Adjusting element is set and / or regulated as a function of a difference of the gas pocket valve position.
