ABSTRACT:
A gas-dynamic pressure wave supercharger includes a multi-cell rotor, a fresh air inlet channel, a high pressure air channel leading to the engine, and high and low pressure exhaust channels, with the high and low pressure exhaust channels enclosed in a gas enclosure, and the fresh air inlet channel and the high pressure charge air channel enclosed in an air enclosure. The high pressure exhaust channel includes an enlarged portion on the rotor side from which a duct extends to the low pressure channel. The duct is so regulated that a part of the exhaust gas is always first conducted from the high pressure exhaust channel into the enlarged portion before additional exhaust gas is conducted through the duct from the high pressure exhaust channel to the low pressure exhaust channel. Improved fuel consumption results over the entire performance range of the engine, particularly in the partial load range.
