Abstract (en)
[origin: WO2011100958A1] The present invention relates to a method for adjusting a charge pressure of an internal combustion engine (A), the charge pressure being built up by a pressure-wave supercharger (B), and a channel 1 (O) for drawing in fresh air, a channel 2 (P) for discharging the compressed fresh air, a channel 3 (Q) for supplying exhaust gas, and a channel 4 (R) for discharging exhaust gas being connected to the pressure-wave supercharger (B), and the pressure-wave supercharger (B) having a cold-gas housing, to which channel 1 (O) and channel 2 (P) are connected, a gas pocket valve (F), which is arranged in the area of channel 3 (Q), and a blowoff valve (H), which connects the channel 2 (P) to the channel 3 (Q), characterized in that a control disk (D) for adjusting the pressure-wave process by means of a geometric offset of channel 3 - 4 from channel 1 - 2 is arranged in the cold-gas housing and the charge pressure is adjusted or controlled according to a control disk position (a) and/or a gas pocket valve position (b) and/or a rotor speed (c) of the pressure-wave supercharger (B) and/or a blowoff valve position (d).
