Název v původním jazyce

Novel Positive-Displacement Engine for the Use of Low-Temperature Heat

Popis výsledku v původním jazyce

The development of a new engine concept is presented as an example of the use of simulation methods in an early stage of design. A novel positive displacement engine component with a cycling piston using conchoid mechanism (unlike a Wankel engine) is used. The five-period cycle realized inside and between four positive displacement components has been developed. The cycle appears to be competitive to current Stirling engine cycles. The heat supply period can be realized in a heat exchanger at controlable pressure/volume conditions combining changes of volume at the second stage of a compressor side and the first of an expander side. Expansion is performed to the atmospheric pressure. The need for low-temperature heat exchanger is avoided by the use ofan open cycle with air as working fluid. The cycle efficiency was estimated by idealized cycle to confirm the potential of the engine at limited heat supply temperatures.
