Abstract: The gas-dynamic pressure wave machine, which is destined for the charge air supply of an internal combustion engine, comprises a rotor, a low pressure fresh air inlet channel, a high pressure charge air channel leading to the internal combustion engine, a high pressure exhaust channel coming from the internal combustion engine, and a low pressure exhaust channel the low pressure exhaust channel and the high pressure exhaust channel being enclosed in a gas housing and the low pressure fresh air inlet channel and the high pressure charge air channel being enclosed in an air housing, and each of all four channels communicating with the rotor through sector-shaped openings in their respective housings. The sector-shaped openings of the high pressure charge air channels are adjustably arranged in order to allow an adjustment of the process over the entire performance field of the internal combustion engine.

Abstract: The engine has an input system formed with a fluid displacement pump that enables substantially continuous pumping from a low-pressure side to a high-pressure side substantially without any backflow or backpressure pulsations. The output system, in one embodiment, is an output system having a turbine rotation about an axis that is substantially orthogonal to the pressure flow originating from the prime mover. The output system may include a first turbine which provides for the mechanical work output of the engine and a second turbine which feeds back to drive the input system. Any increase in the load to be driven by the first turbine translates into a proportional increase in the drive energy fed back to the input system. In an alternative embodiment, a differential may be used to distribute the output power to a load or back to the input compressor.

Abstract: A wave rotor apparatus and method of using the transient gas dynamic processes within the wave rotor to accomplish an engine topping cycle. In one form of the present invention the wave rotor is a five port device. Working fluid from the highest pressure outlet port is routed to a port adjacent to and preceding an inlet port admitting air from the compressor. In a preferred form of the present invention there are two port sequences disposed along the circumference of the wave rotor apparatus.
