| 摘要 |
The gas-dynamic pressure wave machine is intended for supplying charge air to an internal combustion engine and comprises a rotor (40) with cells (41), a low pressure fresh air inlet channel, a high pressure charge air channel leading to the internal combustion engine, a high pressure exhaust gas channel (31) coming from the internal combustion engine, and a low pressure exhaust gas channel (35), the low pressure exhaust gas channel (35) and the high pressure exhaust gas channel (31) being enclosed in a gas enclosure (34), and the low pressure fresh air inlet channel and the high pressure charge air channel being enclosed in an air enclosure, and the high pressure exhaust gas channel being provided on the rotor side with a widened portion (53). A duct leading from the high pressure channel (31) to the low pressure channel (35) is provided which is regulated by suitable means (59) for maintaining the pressure wave process in such a manner that a part of the exhaust gas flow is always first conducted from the high pressure exhaust gas channel (31) into the widened portion (53) before additional exhaust gas is conducted from the high pressure exhaust gas channel to the low pressure exhaust gas channel in the duct (57). By these measures, improved consumption values are obtained over the entire performance range of the internal combustion engine, particularly in the partial load range.
