ABSTRACT:
In the case of a gas-dynamic pressure-wave supercharger for the supercharging of an internal combustion engine, an exhaust bypass in the gas housing (2), with a medium-controlled gate, connects the high-pressure gas inflow duct (4) to the low-pressure gas outflow duct (6). The exhaust gas blown off is introduced via a waste gate ejector (33), which is located in the region of the closing edge (30) in the low-pressure gas outflow duct (6), into the latter. Consequently, the energy level of the low-energy scavenging air can be increased, which improves the compression efficiency of the pressure-wave supercharger.
