Patent ID: 8136512

Claim:
A method for operating a pressure-wave supercharger, the method comprising: compressing fresh air with the pressure-wave supercharger, the pressure-wave supercharger including at least two channels, an exhaust gas channel and a charge air channel, a misalignment of the exhaust gas channel and the charge air channel being adjustable; determining at least one thermodynamic state variable; determining the misalignment of the exhaust gas channel and the charge air channel based at least in part on the at least one thermodynamic state variable; and adjusting the misalignment of the exhaust gas channel and the charge air channel based at least in part on the determining of the misalignment, wherein the determining at least one thermodynamic state variable is based at least in part on a time between a pressure-wave moving from one side of the pressure-wave supercharger to an opposing side of the pressure-wave supercharger.
