Abstract:
A gas-dynamic pressure wave machine for a charge air supply of an internal combustion engine, the pressure wave machine comprising:a driven rotor; an air housing having an air inlet channel in communication with the rotor and a charge air channel leading from the rotor to an inlet of the internal combustion engine; a gas housing having a first exhaust channel leading from an exhaust of the internal combustion engine to the rotor and a second exhaust channel in communication with the rotor, each one of the channels communicating with the rotor through openings in their respective housings, the air housing being rotatable around an axis of each the rotor and the gas housing such that the openings of the charge air channel and the first exhaust air channel are selectively aligned so as to adjust the pressure wave over the entire performance field of the internal combustion engine.
