Abstract

A heat engine of the rotary vane type and thermodynamic cycle is disclosed. The engine converts thermal energy contained within relatively low temperature hot gasses into mechanical energy. The engine operates by expanding a hot gas to a lower pressure than its starting pressure, cooling the gas briefly at a approximately constant volume and then cooling the gas further while compressing it back to its original pressure. Possible sources of hot gasses for powering the engine include exhaust gasses from other engines and air heated by solar collectors.
